ISAMILL FINE GRINDING TECHNOLOGY AND ITS
The IsaMill is a horizontal high speed stirred mill that operates with very high power intensities (up to 350 kW/m3). In comparison, the power intensity of a ball mill is about 20 kW/m3. The high power intensity enables the IsaMill to process fine particles at a high throughput that is essential for the economics of the minerals industry.

Water Consumption at Copper Mines in Arizona
Fresh water consumption at the concentrator plant is around 200 gallons/ton of ore. If recirculation is maximized, leaks are avoided, and evaporation is reduced, the water use may be optimized to about 90 gallons/ton of material, as has been shown to be possible in some plants in Chile. Causes of water losses include:

Factors having an Effect on the Power Consumption & Capacity of a Mill
The third area in a concentrator where significant power savings are possible is in the flotation section. The larger cells, 300 cubic feet or more, can save up to 1 KWHr/ton. Based on reports from 17 operations, a power consumption varying from 1.0 to 2.0 KWHr/ton is normal. More than half fell in this range.
