On April 15, manganese ore quotations increased further today, and the quotation also rose further by 0.5-1 yuan / tonnage. Under the combined influence of the recent continuous upward increase in the national average price of threads and the sharp rise in bidding for steel mills in East China, some operators continue to be bullish on the prices of silicon, manganese and manganese ore in May. According to the current steel mill profits and terminal consumption, steel mills are still likely to suppress raw material prices, and transport restrictions in Port Elizabeth and Saldania Bay, the main ports for manganese ore transport in South Africa, may be slowly relaxed. It is not clear whether manganese prices can rise further.
