Yesterday, quotations for cobalt chloride and cobalt sulfate generally extended their upward trend, but the market broadly exhibited a pronounced pattern of higher quotations with scarce transactions. Although quotations were raised across the board, the core issue in the spot cobalt salt market that day was not the direction of prices but the extremely thin trading activity. Spot electrolytic cobalt was quoted but not traded, with only a handful of sporadic deals and mostly exploratory offers. Large-lot transactions for cobalt sulfate and cobalt chloride were relatively scarce, with trading mainly confined to small and scattered orders.The underlying impetus for the rise in cobalt salts yesterday still came from expectations of supply contraction under the export quota constraints of the Democratic Republic of the Congo (DRC). However, this supply-side logic has not yet translated into actual purchasing volumes in the cobalt salt segment.
