How does cobalt carbonate pricing track broader cobalt salt and metal markets?
Cobalt carbonate is a key intermediate in the cobalt value chain, and its pricing moves in tandem with upstream metal and downstream oxide markets. Recent spot checks show cobalt carbonate at 222 yuan per kg, while cobalt sulfate trades at 96 yuan per kg and cobalt tetroxide at 404 yuan per kg. The spread reflects processing costs and end-market demand: carbonate feeds into ceramics, catalysts, and battery precursor production. Metal cobalt prices have shown more volatility — electrolytic cobalt rebounded 2,000 yuan to 430,500 yuan per tonne on one trading day, while nickel dropped 1,850 yuan. Cobalt salts have remained stable, suggesting downstream buyers are comfortable with current inventory levels. The market is watching DRC supply disruptions closely, as any prolonged outage would cascade through carbonate prices given its role as a feedstock for cobalt oxide and other derivatives.
