WEBOct 1, 2015 · The present study clarifies the possibility of using a mixture of chromite ore, mill scale and coke as the precursor for direct chromium alloying. This method offers an alternative process route with cheaper raw materials and fewer process steps (by avoiding the step of ferrochrome production) for producing high chromium iron or steel alloys.
