Abstract:

The Co Dinh chromite ore contains nearly 70% of -0.02 mm size fraction causing it, especially the finest fraction, to be hardly washable by gravity separation. The mine gravity concentrator and most of domestic researches, thus, pay great efforts mostly on the processing of the coarser size fraction (+0.05 mm) using spirals, shaking tables, multigravity separators etc. The fine fraction of -0.05 mm is almost ignored so this leads to a low overal recovery. This paper is to presents resuls of the study on the chromite recovery from 0.02÷0.074 mm size fraction of Co Dinh chromite ore by a combination of Knelson separators and slime shaking tables. The obtained results showed that a gravity concentrate of 40.18% Cr2O3 with the recovery of 26.20% could be produced.
