Zambia’s average copper grade per tonne of ore mined dropped from 1.26% in 2014 to 0.80% in 2017 largely due to the ramping up of First Quantum’s large, low-grade Sentinel open-pit mine that at full capacity will produce 270ktpa of copper in concentrate from 55Mtpa of ore grading approximately 0.55% copper in its first ten years.

Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.

(green feed) ore concentrate produces matte, a molten mixture of copper sulfide (Cu2S), iron sulfide (FeS), and some heavy metals. Converting the matte yields a high-grade "blister" copper, with 98.5 to 99.5 percent copper. Typically, blister copper is then fire-refined in an anode furnace, cast into

Copper ore is extracted from the earth, then converted into copper concentrate, which is then roasted, smelted and converted into refined copper. The resultant metal is widely used for its high electrical and heat conductivity; its malleability; its ability to form alloys with other metals; and its resistance to corrosion.

The ore grade of a mine is an important state variable as well because it determines the amount of copper per volume of extracted ore. This is the most important determinant of a mine average cost because it can generate large di⁄erences in output for given amounts of (other) inputs.

Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps.

This means that 95.7% of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from 100%: % Cu Loss = 100 – 95.7 = 4.3% This means that 4.3% of the copper present in the ore was lost in the tailings.

According to the metallurgy process, the copper ore is divided into three natural types by the ratio of copper oxide and copper sulfide. That is, sulfide ore, containing less than 10% copper oxide; oxidized ore, containing more than 30% copper oxide; mixed ore, containing 10% to 30% of copper oxide.
