METALLURGICAL USES FLUXES FOR METALLURGY HAROLD R. KOKAL AND MADHU G. RANADE A metallurgicalf2ux is a substance that is added to coine with gangue (unwanted minerals) during ore smelting, with impurities in a molten metal, or with
The removal of metal impurities from metallurgical grade silicon (MG-Si) by acid leaching has been investigated with the addition of CaO. Prior to adding CaO, Fe is the main impurity in the MG-Si sample, and the 2nd-phase precipitates in silicon are Si-Fe-based alloys, such as Si-Fe, Si-Fe-Ti, Si-Fe-Al, Si-Fe-Mn, and Si-Fe-Ni. The phases of Si-Fe and Si-Fe-Ti are not appreciably soluble in HCl
