Galvanic interaction of grinding media with

2018-1-15  The synthetic ores were prepared by mixing arsenopyrite or pyrite with clean gravity gold concentrate and quartz. In the presence of arsenopyrite, the results showed that when the grinding of the ore was performed using the 30% chromium or ceramic grinding media, the gold leaching was more efficient than that when the forged steel media was used.

[PDF] Grinding media quality assurance for the

Highly abrasive ores, such as those in the gold industry, can consume about 1 to 2 kg of grinding media per ton of ore milled3. As a result, grinding media replenishment is one of the highest above-the-ground consumable cost for mines – therefore an improvement in wear characteristics and life, or decrease in price of grinding media, can represent a significant saving.
