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 produce ferrochrome. Basicity was controlled by the addition of limestone and it was varied from …
In steel production, Chromite Sand is used as well filler for protection of the sliding gate in large steel holding ladles. When ground to a fine flour, Chromite Sand is used for the production of green glass beverage containers.

Russia (0.5%), Brazil (0.2%), and others (6.9%)South Africa South Africa South Africa is the world's largest source of chromite. Historically it has accounted for approximately 72 percent of global reserves, as shown in Figure 2. As a result of South Africa's abundant chromite reserves, it has well developed
Unlike conventional sand moulds, chromite moulds can be hard to recover and reuse should there be moderate-to-high amounts of silica present. This is due to a greater likelihood of the chrome becoming contaminated by the silica, and thus its refractoriness is reduced(4). ... High purity chromite occurs naturally in South Africa(18), the same ...
