Cobalt — material dossier

Structural facts + context. Verified components marked.

What it is

Transition metal, atomic number 27. Hard, grey, high melting point (1,493°C). Historically known for blue pigments ("cobalt blue" in ceramics); industrially most important now as a battery cathode material and superalloy additive.

Unusual structural feature: cobalt is almost never mined primarily — it's a byproduct of nickel or copper mining. This means cobalt supply is largely determined by the economics of nickel and copper production, not by cobalt demand/price. Which makes cobalt price swings more volatile than most industrial metals: supply is sticky downward even when price falls (the parent miners keep producing copper/nickel), and sticky upward even when price rises (no one builds a cobalt- primary mine).

Price state (verified 2026-04-23 via Trading Economics)

Cobalt rallied sharply YTD (+67%) after bottoming out. Current level ~60% of the March 2018 all-time high, above the long-run average of recent years. Notable that price is flat MoM and day-over-day — the YTD rally happened earlier in Q1 2026 and has consolidated.

Where it comes from (verified where noted)

Mine production (2025, verified via Statista summary + TE)

• Democratic Republic of Congo (DRC): >50% of global cobalt

mine production. Has held this position since the 1960s. Much of the output is small-scale / artisanal (a major ESG issue).

• Russia: ~4% (Norilsk nickel byproduct)
• Rest: Australia, Philippines, Cuba, Indonesia, Canada, Madagascar
• Indonesia is the fastest-growing source — nickel HPAL

(high-pressure acid leach) projects produce cobalt as byproduct, and Indonesia has been massively expanding nickel output for EV batteries. Over time this diversifies the DRC concentration.

DRC supply structure (critical detail)

• Largely Chinese-owned or Chinese-financed: CMOC (Tenke

Fungurume), Zijin (Kamoa-Kakula cobalt byproduct), Glencore (Katanga/KCC) — Glencore is Swiss but sells much of its offtake into Chinese refining

• Artisanal mining (ASM) accounts for ~15-25% of DRC output,

depending on price. ASM surges when cobalt is high because individual miners enter the market.

• ESG risk: child labour, unsafe conditions, environmental

damage. Apple, Tesla, and others have faced lawsuits and supply-chain due-diligence pressure.

Refining

• China ~70-75% of global cobalt refining (chemicals and

metal). Most DRC concentrate ships to China for processing into cobalt sulfate (battery-grade) or cobalt metal.

• Finland (Umicore), Belgium (Umicore), Japan (Sumitomo) next

tier

• Artisanal ore also routes through Chinese smelters

Demand structure (verified applications from TE)

• Chemicals (batteries, pigments, catalysts): 58%

- Batteries specifically: ~60-70% of total cobalt demand - LCO (laptops/phones), NCM (EVs), NCA (EVs, Tesla)

• Superalloys (jet engines, gas turbines): ~18%
• Specialised steels & tool steels: ~8%
• Magnets (samarium-cobalt, alnico): ~6%
• Other (catalysts, pigments, medical): ~10%

Key structural trend: battery chemistry is migrating AWAY from cobalt

• LFP (lithium iron phosphate) chemistries use zero cobalt
• LFP share of EV batteries grew from ~20% (2020) to ~55% (2024)
• Even NCM chemistries are moving to low-cobalt variants

(NCM-8-1-1, NCM-9-0.5-0.5)

• This is the biggest structural headwind for cobalt demand

Counter-force: ABS / UK / EU defence spending is supportive of superalloys (jet engines, missiles). This is a smaller slice but growing.

Policy / geopolitical context

• US IRA FEOC rules — DRC cobalt refined in China is treated

as "foreign entity of concern", disqualifying vehicles from the $7,500 EV tax credit. Creates premium for non-Chinese- refined cobalt (Umicore, Finnish/Korean refining).

• EU CRMA — cobalt on strategic list; 10% mining, 40%

processing, 25% recycling targets by 2030 (though "domestic cobalt mining" mostly means "recycling" for Europe).

• DRC domestic policy — the Tshisekedi government has

pushed for more value capture from Chinese-owned mines (renegotiated Sicomines 2024). Artisanal mining regulation tightening, slowly, but chronically under-enforced.

• US "Minerals for Security" agreements — DoD funding

going to non-Chinese-aligned projects (Jervois, Electra Battery Materials)

• China — no cobalt export controls; has toll-refining

capacity advantage and long-term offtakes

Concentration risks (ranked)

1. DRC political/security disruption — election cycles, Kasai/Kivu regional instability, recurring community conflicts. Could cut 10-20% of global supply quickly. 2. DRC policy tightening on Chinese operators — the Sicomines renegotiation template could extend to other Chinese-operated mines (CMOC Tenke Fungurume etc.), creating regulatory uncertainty 3. Chinese refining chokepoint — no current export controls but structurally available 4. Battery chemistry migration to LFP — NOT a disruption risk but a multi-year demand erosion

Interesting asymmetry: cobalt has declining structural demand (LFP share rising) but concentrated acute supply risk (DRC). So long-term bear case vs short-term volatility skewed to upside from supply shocks.

Players to know

Producers (primary + byproduct)

• Glencore — Katanga/KCC, Mutanda in DRC; world's #2

cobalt producer

• CMOC (China Molybdenum) — Tenke Fungurume (DRC),

world's #1 cobalt producer. Acquired 2016 from Freeport.

• Zijin Mining — Kamoa-Kakula (DRC, copper primary,

cobalt byproduct)

• Norilsk Nickel (Russia) — nickel primary, cobalt byproduct
• Sumitomo Metal Mining (Japan) — nickel + cobalt
• Vale Indonesia — nickel HPAL + cobalt byproduct
• Jervois Global — US/Finland cobalt refining

Non-Chinese refining / downstream

• Umicore (Belgium) — cobalt cathode material
• Freeport Cobalt (was Freeport, now merged) — Finland
• Sherritt (Canada/Cuba) — vertically integrated
• Electra Battery Materials (Canada) — cobalt refining
• LG Chem / Samsung SDI / POSCO — Korean cathode makers

What to watch monthly

• LME cobalt spot + 3m curve
• CMOC + Glencore quarterly cobalt production
• DRC political developments (especially around election or

mining-code revisions)

• Indonesia HPAL project commissioning (Morowali, Weda Bay)
• Tesla / CATL / BYD chemistry-mix disclosures (LFP vs NCM

share)

• Jet engine delivery data (Boeing, Airbus, Rolls-Royce) —

superalloy demand proxy
