The production costs of ferro silicon and silicon manganese

The production costs of ferro silicon and silicon manganese are as follows:

The production cost of silicon manganese: Manganese ore: Each ton of silicon manganese requires 2 tons of manganese ore as the basic raw material, accounting for 55%-65% of the total cost, which is the key determinant of the cost of silicon manganese. Manganese-rich slag: Each ton of silicomanganese requires 0.75 tons of manganese-rich slag, accounting for 10%-15% of the total cost. Electricity: Each ton of silicomanganese consumes 4,000 kWh of electricity, accounting for 15%-20% of the total cost, and plays an important role in power-intensive industries. Silica: Each ton of silicomanganese requires 0.26 tons of silica, accounting for about 10% of the total cost. Other expenses: Depreciation and other miscellaneous expenses total 250 yuan. Comprehensive calculation, the cost of each ton of silicomanganese is about 8,000 yuan.

The production cost of ferro silicon: Silica: Each ton of ferrosilicon requires 1.8 tons of silica, accounting for 10%-15% of the cost share. Electricity: Each ton of ferro silicon consumes 8,000 kWh of electricity, accounting for 50%, showing the dominant position of electricity costs in ferrosilicon production. Semi-coke: 1 ton of semi-coke is needed for every ton of ferrosilicon, accounting for 25%-30% of the total cost. Pellets: 0.2 ton of pellets is needed for every ton of ferro silicon, accounting for 5%-10% of the total cost. Other expenses: Depreciation and other expenses total 250 yuan. In general, the cost of each ton of ferro silicon is about 7,000 yuan.
