Corrosion During Ore Grinding

The total grinding ball wear rate is 1.13 lb/st of dry ore, and mill throughput is 85 st/h. This is equivalent to a linear penetration rate of about 2,600 mpy; therefore, corrosion is directly responsible for about 1 pct of the total grinding media wear at Magma Copper Co.
