Chromite Beneficiation Process

Apr 12, 2016 Chromite Process Summary. This flowsheet is very effective due to the ability to remove the high grade chrome with very little grinding on each pass through the mill. In this way, grinding takes place with a large number of small reductions followed by immediate removal of the liberated chrome into a high grade concentrate.

Binder Behavior on Chromite Carbon Composite Pellets

different binders to agglomerate carbon composite chromite ore, with emphasis on the temperature range of 1173-1573 K. The alternative binders tested were bentonite, with or without the addition of CMC (Carboxymethylcellulose), and sodium silicate. Bentonite is the most commonly used binder for the traditional pelletizing process of iron ore.

Unique challenges of clay binders in a pelletised chromite

Jul 01, 2012 In this process fine chromite ore, a clay binder and a carbon reductant are dry milled, pelletised and pre-heated before being fed into a rotary kiln where the chromite is partially pre-reduced. The pre-reduced pellets are then charged hot, immediately after exiting the kiln, into closed SAFs (Beukes et al., 2010, Naiker, 2007).
