A Preliminary Investigation of the Operating Variables in a Laboratory Knelson Concentrator for Enrichment of Chromite Ore
Abstract
The article describes the experimental studies on the recovery of chromite ore obtained from the Askale-Kop deposit (Erzurum/Turkey) using a laboratory-type KC-MD3 Knelson concentrator. For this purpose, the parameters of pulp feed rate, fluidization water flow rate, pulp solids ratio bowl speed and particle size were examined as variables in the experimental studies. As a result of the experiments, the maximum Cr2O3 grade was obtained at 54.68% in chromite concentrate at fluidization water flow rate of 12 l/min, pulp feed rate of 1.5 l/min, pulp solids ratio of 20% and bowl speed of 800 rpm. The highest concentrate recovery value (76.85%) was obtained at fluidization water flow rate of 6 l/min, pulp feed rate of 1.5 l/min, pulp solids ratio of 20% and bowl speed of 1080 rpm.
