Morenci Copper Mine, Arizona
While high-graded ore is conveyed to leach pads within the pit, the bulk of the primary crusher output (63,500t/d of ore) is secondary crushed and conveyed to the Stargo dump-leaching site. This ore is agglomerated for spreading by two Rahco mobile stacking units. Leaching is bacterially assisted, with air blown into alternate lifts.

BACKGROUND REPORT PRIMARY COPPER SMELTING Prepared for
Copper is mined from a variety of ores, often containing less than one percent copper. This copper is typically in the form of mineral compounds with sulfur, iron, arsenic, and tin. To facilitate transportation to smelters, concentration to about 30 percent copper content is accomplished at the mine sites via crushing, grinding, and flotation.

Ore Crushing
Ore Crushing Operations. Outside of the Mission South Mill, trucks dump the ore into the primary crusher which reduces the rocks to 8 inches or smaller. Inside the mill, the ore is mixed with water in two rotating SAG mills which use the larger rocks and 8-inch steel balls to reduce the ore to about 10 mm or smaller.

copper mining and processing
The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached. First the copper ore from a open pit mine is blasted, loaded and transported to the primary crushers. Then the ore is crushed and screened, with the fine sulfide ore (~-0.5 mm) going to froth flotation cells for recovery of copper.

A crusher’s wear parts need to last as long as operationally-economically possible. Typical numbers are for liner and mantles to have a useful wear-life of almost 2,000,000 tonne on abrasive taconite and 9,000,000 tonnes on porphyry copper ores. Dependability and long service life are landmarks of good primary crusher design of up to 30 yrs.

Primary Crusher
Crushing is typically a dry operation that is performed in two- or three-stages (i.e., primary, secondary, tertiary crushing). Lumps of run-of-mine ore as large as 1.5 m across are reduced in the primary crushing stage to 10–20 cm in heavy-duty machines. In most operations, the primary crushing schedule is the same as the mining schedule.
