Kolwezi cobalt — the artisanal supply chain that doesn't begin at the smelter

<p>The Democratic Republic of Congo produces roughly 70% of the world&#x27;s cobalt. About 20% of that comes from artisanal and small-scale mining — *creuseurs* working with hand tools and basic safety equipment in pits adjacent to industrial concessions, mostly in Lualaba and Haut-Katanga provinces. The remaining 80% is industrial production from companies like CMOC, Glencore, and Ivanhoe.</p> <p>Battery manufacturers and Western governments have been promising &#x27;clean&#x27; supply chains for the better part of a decade. The Responsible Cobalt Initiative, the Cobalt Action Partnership, the OECD Due Diligence Guidance — there is no shortage of frameworks. The operational reality I see weekly at the Kolwezi *négociant* depots and at the SAEMAPE (state regulator) offices is that the frameworks address the *industrial* supply chain. The artisanal supply chain is structurally outside their scope, by the choice of every actor who matters.</p> <p>A typical artisanal sequence: *creuseurs* dig hand-shaft pits 10 to 40 metres deep, extract heterogenite ore by headlamp, surface it, wash and hand-sort it at a *bourse* yard. Buyers — *négociants*, sometimes Chinese, sometimes Lebanese, sometimes Congolese — purchase by the kilogram at a grade-dependent price. The ore moves to a depot, gets blended with industrial low-grade material, and enters the export stream at a smelter or concentrate plant. By the time it leaves Lubumbashi, the artisanal origin is invisible.</p> <p>This is not an accident of due diligence. It is the design. Industrial-scale customers buying cobalt hydroxide cannot, with the current analytical methods, distinguish artisanal from industrial inputs once blended. Their suppliers know that. The &#x27;chain of custody&#x27; documentation generated by RCI-style frameworks documents the industrial portion of the chain credibly. It documents the artisanal portion through self-declaration that everyone involved knows to be partial.</p> <p>The credible reform — the one Pact, IPIS, and the Congolese state mining company EGC have been working towards — is *zoned artisanal mining*. State-recognised artisanal zones (ZEAs) with cooperative governance, mandatory safety equipment, audited child-labour exclusion, and direct sale to a state buying entity that aggregates and certifies. There are now eight such ZEAs operational. The model works where it has been implemented. The bottleneck is the political economy of the *négociant* layer, which would be cut out by a functioning ZEA system and is therefore organising to slow it.</p> <p>What battery manufacturers and policymakers in Brussels and Washington have to understand is that &#x27;no Congolese artisanal cobalt&#x27; is not a credible commitment — the volumes are needed and the market mechanisms blend the inputs. &#x27;Audited Congolese artisanal cobalt via certified zones&#x27; is the only honest option. Pretending otherwise is the form of compliance theatre that keeps the *creuseur* working in conditions everyone has agreed to deplore and nothing has agreed to fix.</p>
