वास्तव में क्या चल रहा है
Cobalt is a by-product: it comes up because somebody wanted the copper. It leaves the DRC as a hydroxide filter cake on a truck, crosses two borders, sails to China, and is refined into the sulfate that goes into a cathode. The route is long, and the due-diligence obligations attached to it are the strictest of any material in this atlas.

चरण दर चरण, और सीमा दर सीमा
Democratic Republic of the Congo · Kolwezi and the Lualaba belt द्वारा धारित Industrial operators and artisanal miners (खनिक)
Industrial mines, and a great deal of hand digging
Most cobalt comes from large mechanised copper mines. A material share is also dug by hand by artisanal miners and sold into the same processing plants, which is why chain-of-custody documentation matters here more than anywhere else in this atlas.
यहाँ क्यों: The Copperbelt. There is no comparable cobalt resource being mined at this scale anywhere else.
Democratic Republic of the Congo · Hydrometallurgical plant द्वारा धारित Operators (रासायनिक)
Leached out with the copper
Cobalt dissolves in the same acid leach as the copper, then is separated and precipitated as a hydroxide once the copper has been electrowon out.
शेष का क्या हुआ: If the copper price falls far enough to close the mine, the cobalt stops too. Its supply follows copper economics, not its own.
यहाँ क्यों: It shares a circuit with the copper because it shares an orebody with it.
Tanzania · To Dar es Salaam or Durban द्वारा धारित Hauliers (व्यापारी)
The long haul
Bagged hydroxide is trucked 2,000 km or more to a port, crossing at least one border. Queues at the crossings routinely add days.
यहाँ क्यों: There is no railway that does this job reliably. The road IS the supply chain.
China · Zhejiang and Jiangxi refineries द्वारा धारित Refiner (शोधनकर्ता)
Into a battery-grade salt
Redissolved, purified of nickel, copper, iron and manganese, and crystallised into cobalt sulfate heptahydrate — pink crystals to a very tight specification.
यहाँ क्यों: This is the real chokepoint. Mining is spread across one country; refining is concentrated in another.
South Korea · Precursor and cathode plants द्वारा धारित Cathode manufacturers (निर्माता)
Into the cathode
Co-precipitated with nickel and manganese sulfates into a precursor, then lithiated and calcined. Cobalt is what keeps the cathode's layered structure from collapsing as it charges and discharges.
यहाँ क्यों: Cathode makers cluster near cell makers, who cluster near carmakers.
Germany · Wherever they are sold द्वारा धारित Drivers (अंतिम उपयोगकर्ता)
About 350 cars
At roughly 13 kg per pack for a mid-nickel chemistry, 4.5 tonnes of cobalt is a few hundred vehicles — and every one of them can be traced back, on paper, to the pit it came from.
शेष का क्या हुआ: Cathode chemistry has been cutting cobalt for a decade — from a third of the cathode metal to under a tenth in high-nickel designs, and to zero in LFP.
यहाँ क्यों: Substitution is the quiet counter-pressure on this entire route.
यह एक कार्यसाधित उदाहरण है। यह एक घोषित आरंभिक मात्रा को प्रकाशित सामान्य उपज और पुनःप्राप्ति दरों के माध्यम से अनुसरण करता है, इसलिए अनुपात जाँचे जा सकते हैं; यह किसी विशिष्ट शिपमेंट का अभिलेख नहीं है। मार्ग संबंधी तथ्य — कौन-से देश, कौन-सी प्रक्रियाएँ, और क्यों सामग्री को कहीं और संभाला नहीं जा सकता — सार्वजनिक रिपोर्टिंग से संकलित हैं।
