miners dispose of wastewaters directly into the rivers and creeks with a simple sedimentation tank in the ball mill facility as their treatment process. This practice contribute to the pollution of the environment and pose health risks to miners and other people living in the mining area (Velasquez-Lopez et al. 2010).

collaboration that compares seven mine mill/concentrator operations: four gold and three iron ore mines. The average energy needed for seven mines is summarized in figure 2, where the energy requirement is broken down into six components:,

Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art - it’s just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results.

The mill heights can be varied to optimize the media load and power input for specific applications. Chamber volumes range up to 50,000 liters with corresponding drives ranging up to 6,500 kW. The HIGmill is the only ultrafine grinding technology in commercial use that can use small-size high-density grinding media in mill sizes above 3000 kW.
