SHANGHAI, May 9 (SMM) - China’s high-purity manganese sulphate output stood at 7,200 mt, down 75.74% on the month. Owing to the serious increase in high-purity manganese sulphate stocks in March and the poor improvement in demand from the new energy sector, high-purity manganese sulphate enterprises either stopped or reduced the production. Therefore, domestic high-purity manganese sulphate output fell sharply in April. In terms of demand, given the high inventory, ternary precursor companies were less willing to purchase in the form of long-term orders. Therefore, even with the output cuts, the supply was still in surplus.
