In slag analysis the total Cr in slag is expressed as Cr203 which varies from 12 to 16% and the slag volume varies from 1 to 1.2 times the weight of metal produced, depending on the gangue constituents in chrome ores and ash content in the reductants used in the process. For each tonne of HC FeCr about 2.35 tonnes of Chromite ores are required.
