Even when recovery of gold and silver from such ores by flotation is low, it may be advantageous still to float off the minerals that interfere with cyanidation, roasting, and leaching or possibly to smelt the concentrate for extraction of its precious metals.
Flotation Plant. A complex sulphide ore of this type requires a high degree of selectivity in the flotation process. The lead and copper must be removed in bulk as a mixed concentrate and then the zinc floated as a separate concentrate because of marketing requirements.

Copper extraction refers to the methods used to obtaining copper from its ores. The 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.
Flotation process was first commercialized in 1896 in copper mining in Llanelltyd Glasdir near Dolgellau in North Wales with sulphide mineral flotation processes conducted by Frank Elmore and his brother Stanley, and he is the developer of the copper mines.

Copper sulfide ore has good inherent floatability, so flotation process is a mature method used for copper sulfide ore separation. In recent years, with the continuous development of copper sulphide flotation technology, many scholars also proposed a series of new principles of mineral processing, such as “collect early, loss early” and “more crushing and less grinding”. At present,

Froth flotation process is considered the most widely used method for ore beneficiation. In copper ore flotation is a precious mineral separation process from of ingredients worthless or other valuable minerals by a induce process the mineral ore, so that ore minerals can accumulate and be …
