The prices of cobalt sulfate increased Yuan 500/t yesterday. Currently, the prices of cobalt intermediates remained stable, and the cost support of cobalt salts was relatively firm. The spot and futures prices of electrolytic cobalt experienced a slight rebound due to market news, fluctuating around Yuan 255,000/t. Smelters still can't lock in prices, and with rising cost expectations for future raw materials, most manufacturers have suspended public quotations. Given the sluggish transmission of upstream raw material prices and weak downstream demand recovery, market transactions are expected to remain limited until the end of the month, with ongoing supply-demand negotiations.
