Korea’s Real Battleground in Critical Materials Isn’t Mining—It’s Smelting and Recycling
If you look at raw materials purely as a game of owning mines, South Korea always seems weak. But once you break down where the money actually gets made, the picture changes. The core of Korea’s raw materials industry is not digging resources out of the ground, but refining what others have mined and recovering it again to add value.
Korea Zinc, Young Poong, LS MnM, SungEel HiTech, POSCO HY Clean Metal. The names alone tell the story. Korea has limited presence in energy commodities or large-scale mining rights, but its companies are deeply embedded in zinc and lead smelting, copper electrorefining, black mass, urban mining, and nickel and cobalt recycling. On the other hand, they are weak in rare earth separation and refining, permanent magnets, overseas resource development, and trading and hedging. The divide between what Korea does well and what it does poorly is strikingly clear. If you lump all of that together as one industry, you will keep missing the point.
The Money Was Made More in Smelting and Refining Than in Digging It Out
If you divide the raw materials value chain very roughly, it spreads across energy commodities, industrial metals, precious metals, rare metals & rare earths, domestic mining & extraction, and agriculture & others. But the segments where Korea is strongest are upstream’s opposite end—not securing mining rights or exploration, but the middle and downstream. Korean companies are closer to players that generate margins in smelting, refining, recovery, and recycling than to players that own the ore itself.
For zinc and lead, there is Korea Zinc and Young Poong’s TSL/QSL. For copper, there is LS MnM’s electrolytic copper. With the battery era, SungEel HiTech, Korea Zinc (Kemco), and POSCO HY Clean Metal have expanded the black mass and recycling axis. In urban mining, LS MnM, Korea Zinc, and Toricom are positioned in precious-metal and rare-metal recovery. In the end, the cash-generation point in Korea’s raw materials space is tied less to “resource ownership” and more to how reliably it can refine and recover difficult-to-process materials.
| Stage | Description | Subsegments |
|---|---|---|
| Energy commodities | Crude oil, LNG, coal, uranium — Korea imports most of its primary energy needs (refining, power generation, and steelmaking demand) | Crude oil & petroleum products, natural gas & LNG, coal, uranium |
| Industrial metals | Iron, copper, aluminum, zinc, nickel — smelting/refining (Korea Zinc, LS MnM, POSCO) and demand (construction, autos, electronics) | Iron ore & steel, copper, aluminum, zinc & lead, nickel |
| Precious metals | Gold, silver, platinum, palladium — safe-haven assets, semiconductors, catalysts, hydrogen (mostly imported, also smelting by-products) | Gold & silver, platinum & palladium |
| Rare metals & rare earths | Lithium, cobalt, rare earths, tungsten — critical for secondary batteries, permanent magnets, and defense; China dependence and stockpiling are key issues | Lithium, cobalt & nickel (battery-grade), rare earths & permanent magnets, tungsten & other rare metals |
| Domestic mining & extraction | Resources mined directly in Korea — limestone (globally significant reserves) and non-metallic minerals are the mainstay, while metallic ores barely survive (cement, steel, electronics, construction) | Limestone & cement raw materials, tungsten (Sangdong Mine), non-metallic minerals (silica, kaolin, pyrophyllite), domestic metallic ores (gold, silver, ilmenite), anthracite |
| Agriculture & others | Grains, soybeans, palm oil, natural rubber — low food self-sufficiency, with grain terminals run by trading houses and food-sector demand | Grains (wheat, corn), soybeans & edible oils, palm oil & bio, natural rubber & others |
What Korea does well, it does exceptionally well. What it doesn’t have, it still doesn’t have.
If you use the word “localization” too broadly in raw materials, you end up with a distorted picture. Korea is not a country that excels at everything. But it is exceptionally sharp in a few specific processes. The real coordinates of Korea’s raw materials industry are here: the technologies where the gap is within 1 are concentrated in smelting and resource recycling.
The strengths are clear. In zinc and lead smelting (TSL/QSL), Korea Zinc and Young Poong hold the line, while LS MnM stands out in copper electrolytic refining. In black mass from waste battery recycling, there are SungEel HiTech, Korea Zinc (KEMCO), and POSCO HY Clean Metal. In urban mining for precious and rare metals, LS MnM, Korea Zinc, and Toricom are active. Nickel and cobalt recycling is also anchored by Korea Zinc (KEMCO), Ecopro, and POSCO. This is not just a case of “being good at recycling.” These are businesses where impurity control, recovery rates, process stability, and feedstock sourcing all have to work together.
The problem is that the weaknesses are just as obvious. Rare earth separation and refining show a gap of 6, overseas resource development a gap of 4, and permanent magnets (NdFeB) also a gap of 4. Deep-sea and future mineral exploration, as well as resource trading and price hedging, come in at a gap of 3. What this combination means is simple. Korea is not a country that controls raw materials and pricing power; it is a country that is very good at processing the materials it is given. Put positively, it is a powerhouse in high-difficulty processing. Put less kindly, it is structurally vulnerable when supply chain shocks hit. If you can’t separate rare earths and you’re weak in magnets too, then what exactly is left if all you do is talk about de-risking?
Table below: domestic and global TRL (technology readiness level 1–9) by technology, and key companies
| Technology | Domestic | Global | Assessment | Key companies |
|---|---|---|---|---|
| Smelting & Refining | ||||
| Zinc & lead smelting (TSL/QSL) | 9 | 9 | Strong · Gap 0 | Korea Zinc, Young Poong |
| Smelting is the process of extracting pure metal from ore using heat and chemical reactions. In zinc and lead smelting, impurities are removed either by melting the ore (pyrometallurgy) or dissolving it in acid (hydrometallurgy). Korea Zinc has secured cost competitiveness through “integrated smelting” technology that recovers around 20 valuable metals in the process, including gold, silver, and indium. On a single-smelter basis, it is the largest in the world. | ||||
| Copper electrolytic refining (electrolytic copper) | 8 | 9 | Strong · Gap 1 | LS MnM (formerly LS-Nikko Copper) |
| This is the technology for smelting copper ore into 99.99% pure electrolytic copper. Ultra-high purity is achieved through electrolytic refining, where an electric current removes impurities onto the cathode plate. That level of purity is essential for use in wire and semiconductors. LS MnM is the only company in Korea operating a large-scale copper smelter. | ||||
| Rare earth separation & refining | 3 | 9 | Weak · Gap 6 | (Effectively no domestic refining companies — imports refined products from China) |
| Rare earths consist of 17 elements mixed together in ore, and the hardest part is “separation and refining” — splitting out elements with very similar properties one by one. It takes hundreds of rounds of solvent extraction to obtain pure neodymium and dysprosium, and China dominates most of this process. Korea has virtually no capability from raw ore to refined metal, so it imports refined products from China. | ||||
| Lithium refining (lithium hydroxide) | 6 | 8 | Catching up · Gap 2 | POSCO Pilbara Lithium Solution, Ecopro Innovation |
| This is the technology for refining lithium extracted from lithium ore (spodumene) or brine into high-purity lithium hydroxide or lithium carbonate suitable for rechargeable batteries. Impurities must be removed down to the ppm level to ensure battery performance and lifespan. POSCO is building out a value chain linking Argentine brine assets with domestic refining plants. | ||||
| Recycling & Urban Mining | ||||
| Waste battery recycling (black mass) | 7 | 8 | Strong · Gap 1 | SungEel HiTech, Korea Zinc (KEMCO), POSCO HY Clean Metal |
| This is a hydrometallurgical process that recovers lithium, nickel, and cobalt by dissolving them in acid from black mass — the fine black powder produced by shredding waste batteries. Because metal content is often higher than in mined ore, it is called “urban mining,” and the recovered metals are fed back into cathode material production. SungEel HiTech is Korea’s leading player. | ||||
| Urban mining recovery of precious and rare metals | 7 | 8 | Strong · Gap 1 | LS MnM, Korea Zinc, Toricom |
| This is the technology for extracting gold, silver, palladium, and copper from electronic waste such as discarded phones and circuit boards. Waste is fed into smelter melting and electrolysis processes to recover valuable metals, and in some cases the gold content is dozens of times higher than in ore. Korea’s advantage lies in leveraging its existing non-ferrous smelting infrastructure. | ||||
| Nickel & cobalt recycling | 7 | 8 | Strong · Gap 1 | Korea Zinc (KEMCO), Ecopro, POSCO |
| This is the technology for converting nickel and cobalt secured through recycling and smelting into high-purity nickel sulfate and cobalt sulfate that can be used directly in rechargeable battery cathodes. It is the final link in the “vertical integration” chain connecting minerals to battery materials within one country, and the key lies in raw material purity and impurity control. | ||||
| Resource Development, Exploration & Trading | ||||
| Overseas resource development (mining rights & equity investment) | 5 | 9 | Weak · Gap 4 | POSCO International, LX International, KOMIR |
| This business secures stable raw material supply by acquiring stakes in overseas mines, oil fields, and gas fields, or by obtaining development rights. General trading companies typically handle it in combination with trading operations, while the government supports it through KOMIR. The sector shrank after large losses in the 2010s, but supply chain disruptions have revived calls for a comeback. | ||||
| Deep-sea and future mineral exploration | 4 | 7 | Caution · Gap 3 | KIOST, Ministry of Oceans and Fisheries, Korea Institute of Geoscience and Mineral Resources |
| This is a future resource technology focused on finding and mining manganese nodules — lumps containing manganese, nickel, and cobalt — or hydrothermal deposits lying thousands of meters below the ocean surface. Korea has already secured exclusive exploration blocks in the Pacific high seas, but commercial mining remains at an early stage due to environmental regulation and technical difficulty. | ||||
| Domestic mining & beneficiation (limestone, tungsten) | 6 | 7 | Strong · Gap 1 | Ssangyong C&E, Hanil Cement, Sungshin Cement, Almonty Korea Tungsten |
| Beneficiation is the process of separating useful minerals from domestically mined ore. Grade is improved through methods such as flotation, where finely crushed ore is separated by differences in properties using water and foam. Korea is self-sufficient in non-metallic minerals such as limestone and silica, but most metal mines were shut down long ago. That said, there are signs of a revival in metallic mining, as the Sangdong tungsten mine in Yeongwol — one of the largest in the world — is set to resume production in 2025. | ||||
| Resource trading & price hedging | 6 | 9 | Caution · Gap 3 | POSCO International, LX International, Hyundai Corporation, Samsung C&T Trading & Investment Group |
| This business combines brokerage and logistics — buying raw materials cheaply and selling them where needed — with hedging through futures and options to offset the risk of sharp price swings. It requires both physical infrastructure such as grain terminals and storage tanks, and financial capability. Korea’s general trading companies handle this business, but they remain smaller in scale than the global trading giants. | ||||
| Materials Processing & Strategic Stockpiling | ||||
| Permanent magnets (NdFeB) | 5 | 9 | Weak · Gap 4 | Sunglim Advanced Industry, Novatech |
| These are the world’s most powerful permanent magnets, made from neodymium, iron, and boron, and they provide the force behind motors in EVs, wind turbines, and robots. The core technology lies in precisely blending rare earths and sintering them under high temperature and pressure, but China dominates the entire chain from raw material refining to finished magnets. Sunglim Advanced Industry is Korea’s only mass producer. | ||||
| Cemented carbide & tungsten materials | 7 | 8 | Strong · Gap 1 | Korea Tungsten, TaeguTec (IMC), Korea Tungsten |
| Cemented carbide, made by hardening tungsten carbide with cobalt, is far harder than steel and is used in cutting tools for machining metal and in defense components. The key lies in precise powder blending and sintering. Most tungsten feedstock is imported, but expectations for raw material self-sufficiency are rising with the restart of the Sangdong mine in Yeongwol, which has world-class reserves. | ||||
| Strategic mineral stockpiling & supply chain management | 6 | 8 | Catching up · Gap 2 | Public Procurement Service, KOMIR |
| This is a system under which the state pre-purchases and stores strategic minerals such as lithium, rare earths, and tungsten for use in times of crisis. The key policy priorities are increasing stockpile days and expanding the list of covered items, but critics say Korea still lags advanced countries such as the U.S. and Japan in both stockpile volume and item coverage. | ||||
| High-purity metals (for semiconductors & electronics) | 6 | 8 | Catching up · Gap 2 | LS MnM, Korea Zinc, Toricom |
| This is the technology for producing 6N-grade (99.9999%) ultra-high-purity copper, nickel, tin, and other metals used in semiconductors and electronics. Metals obtained through smelting are further refined to remove impurities to the extreme, and the finer the circuitry, the higher the purity requirement. It is a high-value-added area that extends Korea’s smelting strengths into advanced materials and components. | ||||

From Korea Tungsten to black mass: why the face of No. 1 changed
If you track how the top companies changed by era, you can see exactly where the center of gravity in the industry moved. From the 1970s to the 1990s, the global leaders were BHP and Rio Tinto, while in Korea the baton passed from Korea Tungsten to Korea Zinc. In the 2000s, the global names were BHP, Vale, and Glencore; in Korea, it was Korea Zinc, POSCO, and the general trading houses. In the 2010s, the global No. 1 narrative shifted to China’s rare earths and refining, while Korea saw the rise of Korea Zinc, Ecopro, and SungEel HiTech. From the 2020s to today, the picture is a head-on clash between China’s export controls and the West’s de-risking push.
| Era | Global No. 1 | Korea No. 1 | Core essence |
|---|---|---|---|
| 1970s–1990s | BHP · Rio Tinto | Korea Tungsten → Korea Zinc | Tungsten exports and the birth of non-ferrous smelting — the start of processing trade in a resource-poor country |
| 2000s | BHP · Vale · Glencore | Korea Zinc · POSCO · general trading houses | The China-driven commodity supercycle — scaled-up smelting and resource development by trading houses |
| 2010s | China (rare earths · refining) | Korea Zinc · Ecopro · SungEel HiTech | Lessons from failed resource development and the rise of battery minerals |
| 2020s–present | China (export controls) vs. the West (de-risking) | Korea Zinc · LS MnM · SungEel HiTech · POSCO | The age of supply chain security — from extraction to protection and circularity |
Leadership was never determined solely by who owned the most mines. At different moments, the winners were separated by smelting and refining, and now by recycling and control over supply chains.
Korea’s position has to be read through that lens. The era of Korea Tungsten is over, and the reason Korea Zinc has endured for so long is its smelting competitiveness. Later, Ecopro and SungEel HiTech came into focus because waste batteries and raw-material circularity in the battery era emerged as a new battleground. The fact that Korea’s representative players today are Korea Zinc, LS MnM, SungEel HiTech, and POSCO is highly symbolic. None of them are mining majors. They are companies strong in processing, recovery, and materials conversion. That said, while China is pressuring the global market through rare earths, refining, and export controls, Korea remains weak in rare earth separation, refining, and magnets. So the country’s current position should not be overstated. Korea is an important workshop in the supply chain, but it is not yet the side designing the board.
The next battleground isn’t rare earths themselves, but who controls the feedstock
What matters going forward is simple: whether strengths in smelting and recycling actually translate into control over feedstock. Korea Zinc, LS MnM, SungEel HiTech, POSCO HY Clean Metal, and Ecopro are names worth continuing to watch. The upside for Korea’s raw materials industry depends less on expanding recycling itself, and more on how firmly that recycling network solidifies into a stable feedstock procurement system.
The risks are just as clear. A gap of 6 in rare earth separation and refining, 4 in permanent magnets, and 4 in overseas resource development are not just blanks on a chart. At a time when China holds the lever on export controls and the West is calling for de-risking, those gaps feed directly into costs and utilization rates. The gap of 3 in resource trading and price hedging is no small issue either. Even if feedstock is secured, earnings will still swing if price volatility cannot be managed. Black mass and urban mining sound like impressive buzzwords, don’t they? They are. But if feedstock, refining, hedging, and end-market access are not tied together as one integrated package, that appeal will not last long.
