Fluxing of South African chromite ore with colemanite
SYNOPSIS. South African chromite ores are smelted using SiO 2 - and CaO-containing fluxes, normally as quartz and limestone respectively. The purpose of SiO 2 is to lower the melting point of the ore, while CaO is added to ensure that the slag that forms on smelting is fluid enough to enable slag/alloy separation and tapping from the furnace.
