In this study, the possibility of concentration of
calcined magnesite ore by multi gravity separator was investigated. The best
results were obtained in the concentration of magnesite which was calcined at
8000C, by multi gravity separator. The optimum operation parameters determined
for the concentration of calcined magnesite ore were as follows; a washwater
flow rate of 3 lt/min., shake amplitude of 15 mm, shake frequency of 4.8 cps,
tilt angle of 40 and drum speed of 200 rpm. The results of concentration
experiments showed that, the saleable concentration containing 78.14% MgO was
obtained with 66.58% recovery.
