Copper Concentrates

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 89%.

For example, the copper content of a good grade copper ore may be only one quarter of one percent. The gold content of a good grade gold ore may be only a few onehundredths of a percent. Therefore, the next step in mining is grinding (or milling) the ore and separating the relatively small quantities of metal from the non

Fine Grinding as Enabling Technology – The IsaMill

• Energy efficiency should be defined in terms of power per unit product recovered, not per tonne of ore. Well targeted grinding will improve recovery. • The energy usage of all production steps should be considered. This includes energy in the blasting, mining, milling and smelting. Eg, higher concentrate grade will reduce
