Producer
Glencore plc (Cobalt Division)
Glencore plc (Baar, Switzerland; LSE: GLEN; ~$250B revenue) is the world's largest cobalt trading house and a major cobalt producer from its DRC operations — specifically the Katanga mining complex (Lualaba Province) which it operates as Kamoto Copper Company (KCC) and Mutanda Mining (MUMI). Glencore produces cobalt hydroxide in the DRC and sells the majority to Chinese cobalt refiners (particularly Huayou and GEM) under long-term offtake agreements, rather than refining to cobalt sulfate itself. Glencore's Murrin Murrin nickel-cobalt operation (Western Australia) also produces cobalt sulfate in Australia — one of the few non-Chinese cobalt sulfate sources. Glencore is primarily a cobalt miner/trader rather than a cobalt sulfate refiner; its direct cobalt sulfate refining represents ~3-5% of global output (Murrin Murrin), but its raw material (DRC cobalt hydroxide) feeds a much larger portion of total supply.

Did you know2024
Glencore's DRC cobalt operations produce cobalt as a co-product of copper mining — the cobalt comes from the same ore body and the same processing step as copper cathode destined for electrical wiring. The two metals are inseparable at the mine and initial refining stage: EV battery cobalt supply and global electrical infrastructure copper supply are co-produced in the same Lualaba Province operations. A shutdown of KCC or Mutanda for safety, political, or environmental reasons simultaneously disrupts battery supply chains for EV manufacturers AND copper supply chains for electrical grid builders — a single operational event with dual industry consequences that most procurement teams in either sector do not model as a shared risk.

Glencore's cobalt dominance was built through two phases: first, inheriting the DRC copper-cobalt assets from the former Zaire through Xstrata and the legacy of Union Miniere (the Belgian colonial mining monopoly that extracted the Congo Basin's copper-cobalt since the 1900s); and second, aggressively controlling cobalt marketing by taking up third-party offtake agreements from independent DRC miners in addition to its own production. Glencore's Katanga/KCC and Mutanda operations in Lualaba Province sit on the central African copper belt, the same geological formation that Belgian colonizers and subsequent Mobutu-era state enterprises exploited for decades before Glencore assembled its current position.
