The chromite deposit of Sukinda belt is mainly stratiform type and can be classified into the categories like lumpy ore, granular ore, friable ore, ferruginous ore, disseminated ore and banded ore.
Iron is replaced by magnesium and similarly chromium by ferric iron and aluminium. It is this replacement that improves Cr:Fe ratio in chromite. Chromium ore occurs exclusively in ultramafic igneous rocks. Commercial chromite deposits are found in two forms stratiform seams and irregular podiform/lenticular deposits.

LG6 has a Cr2O3 content of 43-47% and a Cr:Fe ratio of 1.6:1, while MG1 averages 42% Cr2O3 …
The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the …

While the industry has been successful in reducing …
A good example is found in the field of ferrochrome where a 3:1 ratio of chromium to iron was considered essential in the manufacture of the alloy. South African producers have demonstrated that an ore with a chrome:iron ratio of 1-6:1 is very suitable and that a resultant product containing 55/60 per cent chromium has
About 40% of the Indian chromite ore reserves are suitable for metallurgical purpose due to higher Cr:Fe ratio.

produced from an ore with a chromium-to-iron ratio of 1,35, even if the chromium recovery is only 93 per cent of the iron recovery. This can be achieved with a slag having 5,7 per cent Cr2O3 and a slag-to-metal ratio of 1,33. A further interesting feature of UG-2 chromites is the fineness of the concentrate (99 per cent of the particles
