chromite processing and recovery ferrochrome
The production of high carbon ferrochrome is a reductive process, and as such changes the oxidation state of the chromium in natural chromite from the plus 3 (Cr3+) oxidation state to zero. Unreduced chromium in the slag is in the 3+ state, which is chemically very stable. With the older semiclosed processes, some hot dust can be subjected to ...
