Grinding media quality assurance for the comminution of gold ores
Annually, large tonnages of ferrous grinding media are consumed around the globe, costing several million dollars2. 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 –
Grinding Media Balls for Mines and Minerals Processing Industry
GRINDING MEDIA FOR THE MINING INDUSTRY There is no standard solution for mineral industry and wear rate of grinding media varies from mine to mine, ore to ore and even for the same ore time to time. Different alloys are recommended depending on ore type and mill particulars in order to arrive at the most cost economic solution.
