Main Copper Sulphide Extraction Process Mining Pedia

2019-12-21  Copper sulfide ore has better floatability than sphalerite, pyrite and another sulphide, so it is more likely to float from the pulp by adsorpting collector. Therefore, froth flotation process is the main mineral process method used for the extraction of copper from copper sulphide.

Sulfide Ore - an overview ScienceDirect Topics

A basic principle of many processes for extracting copper and nickel from sulfide ores is to overlay the molten ore or matte with a lime–silica–iron oxide slag and blow with air or oxygen. Some of the iron present in the ore oxidizes and as a result, partitions to the slag phase, while some of the sulfur is carried off as sulfur dioxide.

Initially, the plant treated about 20,000 tonnes of ore per month using a single flotation circuit with conventional reagents such as xanthates and pine oil. Over the period 1937 to 1940, the concentrator was extended to allow the differential flotation of Cu–Zn.
