Magnetic
separation has been used widely since 1955 for processing a variety of minerals
from iron ore in steel production to desulphurization of coal.
The
accumulation of fines and tailing during mineral processing operations and the
increasing global demand for quality products motivated the use of the
semi-continuous pilot wet high gradient magnetic separator. In this study the
possibility of recover the chromites from the tailings of the chromite
enrichment plant, by vertical ring and pulsating high gradient wet magnetic
separator (VPHGMS) was investigated. Magnetic separation and concentration
experiments were studied on pilot scale laboratory with 1-5 tons tailing
materials. Tailings were fed first to hydrocyclone then the bottom fluid of the
cyclone was fed to magnetic separator. Pre concentrate, obtained by magnetic
separator, was beneficiated by shaking tables as a final enrichment step. On
the experimental studies different currents (100-400 amperages) were studied to
find out the effect of these parameters on the Cr2O3
grades and on the recovery yield. Therefore the parameters were evaluated in
collaboration with particle size distributions, grades and the quantity of
feeding and concentrate. According to experiments 300 amperage was determined
as an optimific value. With reference to results 47% Cr2O3
concentrates were produced from approximately 3.40 % Cr2O3
tailings. Also the efficiency of chromite beneficiation for magnetic and
shaking table tests was changed between 40-70 %.
