Project: Mineral Comminution
Region: Greenland & Europe
Grinding Solutions was asked to optimise grinding conditions for increased mineral recovery from base metal and refractory gold ores. Both projects involved laboratory based ultrafine grinding trials using SMD milling equipment. The base metal project was based around increasing the recovery of galena in a lead rougher flotation system without generating excessive fines (slimes) during grinding and the refractory gold project was associated with maximising gold liberation in order to optimise the recovery of gold from subsequent cyanide leaching. Both projects required initial grind curve calibration tests used to determine the optimum grinding condition which were then used to produce samples for further metallurgical testing.
