limestone strata from southern Sweden (Schmitz et al. 2003 Schmitz and Hggstrm 2006). The search for fossil meteorites is time-consuming and requires screening of thousands of cubic meters of limestone, whereas sediment-dispersed EC grains can be searched in samples of 1050 kg. Chromite is highly resistant to weathering and it is one of the
In this description the term chromite, following the recent usage recommended by Thayer (1956, p. 14), refers to the mineral chromite. To distinguish between the mineral and the commercial ore, which is also commonly referred to as chromite, the ore is
Extraction of Ferrochrome. Ferro chrome is the ferro alloy of iron and chromium. It is extracted from chromite. The chromite ore is crushed and cleaned properly. It is beneficiated and gangue minerals are separated. The ore concentrate is put in a submerged electric arc furnace. Coke and limestone is added to the ore.
The process followed by another magnetic separation, thus the Cr/Fe ratio was increased from 0.9 to 1.6. The reduction process used coconut shell charcoal as reductant and limestone as an additive. The beneficiated sand chromite was briquette using bentonite as a binder in 2 wt.% before it was smelted in a submerged electric arc furnace to ...
