Chrome Smelting Production Costs :

Chrome Ores on Ferrochrome Smelting

2015-3-12  3,300-3,800 kWh per ton of metal produced. The cost of electricity counts for about 35-40% of total production cost. Due to the shortage of power supply in South Africa, the cost of electricity has more than doubled since 2008, and a plan has been tabled to increase the electricity price by 16% every year from 2013 to 2018.

2021-9-12  lifted a ban on chrome exports that had been in place since 2011 and eliminated a 20 percent export tax to help the sector. The original intent of the prior ban was to increase the smelting of chrome ore into ferrochrome in Zimbabwe. Instead chrome stockpiles grew because of the lack of smelting capacity, high production costs and power shortages.

EFFECT OF CHROME ORE QUALITY ON FERROCHROME

Cost analysis of chrome ore reduction is one of the important issues facing ferrochrome producers in today’s competitive environment. Much of this depends on quality and various ratios in the actual ore. The latter can have a direct bearing on electricity consumption and optimum efficiency of the furnaces. While the industry has been successful in reducing costs by designing larger and more ...
