N2  - Magneticseparation has been used widely since 1955 for processing a variety of mineralsfrom iron ore in steel production to desulphurization of coal. Theaccumulation of fines and tailing during mineral processing operations and theincreasing global demand for quality products motivated the use of thesemi-continuous pilot wet high gradient magnetic separator. In this study thepossibility of recover the chromites from the tailings of the chromiteenrichment plant, by vertical ring and pulsating high gradient wet magneticseparator (VPHGMS) was investigated. Magnetic separation and concentrationexperiments were studied on pilot scale laboratory with 1-5 tons tailingmaterials. Tailings were fed first to hydrocyclone then the bottom fluid of thecyclone was fed to magnetic separator. Pre concentrate, obtained by magneticseparator, was beneficiated by shaking tables as a final enrichment step. Onthe experimental studies different currents (100-400 amperages) were studied tofind out the effect of these parameters on the Cr2O3grades and on the recovery yield. Therefore the parameters were evaluated incollaboration with particle size distributions, grades and the quantity offeeding and concentrate. According to experiments 300 amperage was determinedas an optimific value. With reference to results 47% Cr2O3concentrates were produced from approximately 3.40 % Cr2O3tailings. Also the efficiency of chromite beneficiation for magnetic andshaking table tests was changed between 40-70 %.
