Copper Ore
13.5.7.3 Flotation of Copper Ore. Copper ore usually contains about 0.5 to 2% copper that occurs in the form of disseminated and stringers. The run of mine ore is reduced from 150 mm to 25 mm size in Jaw and Cone crushers. The crushed ore is grinded in ball mills to −74 μm size.

Copper Ore
In most cases, the thin-layer process was used where crushed ores (80% −0.5 in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 L·hour −1 ·m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.

Energy Efficiency & Copper Hydrometallurgy
Crushed ore heap leaching (of secondary sulfides) consumes approximately half the energy of milling-flotation-smelting process
copper produced in the United States originated from flotation (Daniel E. Edelstein, Copper Commodity Specialist, U.S. Geological Survey, written commun., March 20, 2012). Copper sulfide ores must be concentrated before they can be economically transported to a smelter.

Copper
The geological conditions create new challenges in your copper mine. Declining ore grades mean less metal production for each ton processed. And as you have to dig deeper and into harder rock you face longer haulage distances and increased wear of your equipment which translates into higher operational costs.

Copper Concentrates
The production of concentrates implies the crushing and later milling of the ore down to a particle size allows releasing copper by flotation. The concentrates from different regions have approximately between 24% up to 36% of copper. Copper concentrates are then submitted to a final filtration and drying process to decrease the humidity to 8-9%.
