The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of Ore The ore is crushed into a fine powder and a suspension is created in water. To this are added, Collectors and Froth Stabilizers.

An ore specimen of about half a tonne was obtained from a lowgrade copper deposit in South Australia. The specimen was cut and polished to expose a flat surface of ~300 mm in diameter. Drill core samples were cut vertically to the polished surface from various locations on the flat surface.

This is certainly the case for copper, where lowgrade ores now comprise the largest remaining deposits, particularly ores containing the mineral chalcopyrite (CuFeS 2). We know that the largest source of copper going forward is a mineral called lowgrade chalcopyrite ore and that [accounts for] something like 80% of all copper mineral value

The lowgrade sections of the ore body were blasted less intensely, so the waste was preferentially distributed to coarse fragments. The ore was then mined, crushed and screened so that the finer, highergrade particles reported to the processing plant; whilst the coarser, lower grade

About 80 % of primary copper production comes from lowgrade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below) 1. Beneficiation by froth flotation of ore to give copper concentrate

Bismuth adversely affects the drawability of copper wire, even at low levels, and its concentration in the refined copper must be kept to less than 0.5 ppm. Testwork was performed on two types of a concentrate having up to 25 times the penalty limit of 0.02% Bi in concentrate. The approximate
