Laboratory studies on ball wear in the grinding of

01/05/1996  For example, the percent increase in ball wear on changing from nitrogen to oxygen flushing during wet grinding was about 97% for the lead-zinc sulphide ore and 84% for the chalcopyrite ore, while only about 34% and 25% for the iron and phosphate ores, respectively. It becomes thus clear that presence of sulphide minerals in any ore would result in enhanced ball wear due to corrosion. It
