Ferroalloy Production Cost

- Jun 22, 2019-

Ferroalloys are mainly produced in electric furnaces, which consume high power and require abundant and inexpensive power resources.


The production of ferroalloys is a highly energy-intensive process, and energy accounts for a large proportion of the cost structure of ferroalloys. In terms of manganese, chromium and silicon, the main varieties of ferroalloys, in addition to the abundant domestic resources and low prices of silica, manganese ore requires about one-third of manganese ore to be imported due to low domestic grade, high mining cost and reserves. The proportion of manganese alloy production costs is relatively large; China's chrome ore resources are extremely scarce, basically relying on imports, and chromium ore accounts for a large proportion of the cost structure of ferrochrome.


The production cost of ferromanganese is mainly composed of the purchase cost of manganese ore, electricity and coke. The cost of manganese ore is about 60%, the electricity cost is about 20%-25%, and the coke cost is about 10%-15%. In addition, many companies in the production of ferromanganese alloy, in addition to the use of domestic low-phosphorus, low-iron, low-sulfur, low-silicon manganese ore, in order to improve the quality of raw materials into the furnace, increase manganese recovery, reduce power consumption and production The cost needs to be smelted after the purchase of some imported ore and domestic mines. Therefore, the fluctuation of manganese ore price, electricity cost and coke price has a great impact on the production of ferromanganese.


Due to the low price of silica, energy consumption accounts for the largest proportion of ferrosilicon production. The production of one ton of ferrosilicon raw materials and electrical energy consumption is: silica 1780-1850 kg, coke 890-930 kg, steel scrap 220-230 kg, electrode paste 45-55 kg, power consumption 8400-9000 kWh / t. In the cost of ferrosilicon, electricity accounts for about 70%.
