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.

from sulde copper concentrate, which mainly contains chalcopyrite mineral (CuFeS 2) and the minor percentage is the secondary copper minerals, such as chalcocite (Cu 2 S), bornite (Cu 5 FeS 4), and covellite (CuS) [7 –9]. The copper concentrate contains copper, iron, sulfur, and also some other harmful elements such as uorine ions [10].
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 : % Cu Loss = 100 – 95.7 = 4.3% This means that 4.3% of the copper present in the ore was lost in the tailings.
