5. Abstract The Ball mill is one of the most important equipment in the world of chemical engineering. It is used in grinding materials like ores, chemicals, etc. The types of ball mills: batch ball mill and continuous ball mill with different grinding media and different design depend on the nature of the input material and the nature of the ...

Bauxite. Lead – Zinc. Rock phosphate. Metal slag. Coal. 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.

Developments in process engineering are unveiling novel approaches to milling in raffinate circuits. Commodities like copper, phosphate, uranium and even gold have the potential to be processed in a way that introduces acid (or highly acidic process water) immediately into the mill feed as …
