· Porphyry copper ores, usually medium to medium hard, require grinding to about 65mesh to economically liberate the copper minerals from the gangue. Although a clean rougher tailing can often be achieved at 65mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate, thus some form of regrinding is necessary on the rougher flotation copper concentrate. It ...
· Thickener Overflow Problems. ... With the increasing use of engineered stockpiles for bio leaching of lowgrade ore or waste rock in copper (and/or lowergrade heap leaching), biometallurgy with high(er) extractions will outperform the expectations only if a thorough feed mineralogy is performed in concert with "downhole" chemical–analytical work. Important recommendations include ...
Copper extraction refers to the methods used to obtain copper from its conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
· Common copper ore concentrate equipment of copper processing plant is a traditional thickener, efficient deep cone thickener, inclined plate thickener; common filter used in a copper mining process plant are disc vacuum filter and a ceramic filter. Xinhai company has a variety of thickeners and filters for customers.

In some sulphide ores of copper, zinc and lead, the concentration is brought by froth flotation this method, the advantage is taken of the preferential wetting of the ore by an oil. The finely ground ore is taken in a tank containing water and 1% of pine oil or turpentine oil. Collectors e. g., pine oils, fatty acids, xanthates, etc. enhance nonwettability of the mineral
