drive system to be overloaded when the mill filled with copper ore is started. For this reason, the mill is stopped only in the case of a failure or planned maintenance work. The aim is to minimize the potential number of start-ups, as the mill at a standstill must be later started under full load. In the case of a prolonged downtime, the ...

The ratio of overburden to ore is sometimes as high as 5 to 1. The ore itself averages less than 0.7% copper in US mines. Copper ore normally is crushed, ground, and concentrated, usually by flotation, to produce a beneficiated ore containing about 25% copper. The ore concentrates are reduced to the metallic state, most often by a ...

percent of the original copper ore) suspended in a water-based slurry that is emplaced in a tailings storage facility (TSF).
