-Experimental Study

Flotation experiments were carried out to study the separation of copper and lead. Through the condition test, it was determined that for the concentrate at a grinding fineness of -200 mesh and a content of 93.85%, the ideal dosage of CMC + sodium sulfite as the inhibitor and Z-200 as the collector was 1000 and 10 g/t, respectively.

Effects of particle size on flotation performance in the

Therefore, in all the experiments of copper-lead separation flotation and gold-lead separation flotation, the separation efficiency of the intermediate size fractions is the highest. A lower SE value of gold-lead for the coarse size fraction may be due to insufficient liberation of gold from galena or other gangue minerals.

Some reagents such as sodium cyanide for the depression of chalcopyrite and sodium dichromate for the depression of galena are employed [4]. Although only small amount of this kind

Introduction to Mineral Processing

2019-10-29 · Froth flotation is again employed to produce marketable concentrates of both. The process is identical in principle to the flotation of other minerals. The figure on the right is a simplified version of a Pb/Zn flotation circuit. The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated.

Copper extraction

2019-10-27 · Copper extraction refers to the methods used to obtain 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. As in all mining operations, the ore must usually be
