The development of froth flotation has improved the recovery of valuable minerals such as copper- and le. The copper flotation tailings are the feed to the sphalerite flotation circuit where the zinc minerals are floated as explained in the lead-zinc flotation section. Sphalerite is first activated with CuSO4 and floated typically at

Sequential Copper–Lead–Zinc Flotation

Jan 08, 2015  With this process, copper was recovered first with MBS depression of lead, zinc and pyrite. Lead was recovered after conditioning, utilizing cyanide as the base depression scheme to control sphalerite and pyrite. In these tests, a zinc flotation was also performed to measure the metallurgical performance of that metal.

Copper extraction - Wikipedia

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 beneficiated (concentrated).

pH Control in Copper Flotation for Maximized Product Yield

Copper ore may be separated from crude ore using a flotation pro­cess that takes advantage of the physical (as opposed to chemical) properties of small copper ore particles. To maximize the copper yield, pH control is necessary in the flotation tanks. A typical copper operation contains many flotation cells, often with a pH sensor in each cell.
