The Role of Rotary Scrubbers in Ore Scrubbing (Washing)

Once ore has been extracted from the ground, scrubbing is one of the first and most important steps in the beneficiation process, indiscriminate of what's being mined. It is typically carried out after primary crushing and involves the combination of the ore with water and agitation in order to break down and separate gangue materials.

Environmental Strategies in the Mining Industry: One ...

During mining, metal-bearing rock called ore is extracted from underground or surface mines. Metal concentrations in ore vary greatly, from less than 1 percent by weight for most gold deposits to over 60 percent for some iron ore deposits; most metallic mineral deposits have ore grades in the range of 1–5 percent by weight.

Crushing and Grinding Wet & Sticky Ore

In the handling of wet, sticky ores such as encountered in tropical areas having distinct dry and rainy seasons, the crushing plant is a section of the mill which must be planned very carefully. Unless this is done, crushing becomes a constant source of trouble resulting in lost production and high milling cost. In some areas rainfall is high for prolonged periods.
