On 30 April, since 00:00 on 6 May, toll road tolls (including toll bridges and tunnels), the cost of transporting raw materials in ferrochromium plants and the cost of transporting ferrochromium increased at a later stage, and most small and medium-sized ferrochromium plants reported increased losses at high mine prices. Castle Peak and Baosteel Desheng respectively announced that the purchase price of high-carbon ferrochromium in May was 5897 yuan and 5900 yuan / 50 tons, which was significantly higher than that of the previous month, but it was still far behind the current retail market quotation. The main reason is that the cost of domestic chromium ore Chaigou is still high in many manufacturers. However, according to the current epidemic situation and policy requirements in Africa, the arrival of domestic chromium mines will improve after May, and the space for speculation at the mine end is limited.
