Copper Mining and Extraction Sulfide Ores

Some impurities form a slag (such as FeO.SiO 2 ), which floats on the surface of the liquid (like oil on water) and is easily removed. (Courtesy of Xstrata.) The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores.

Mining Industry Copper Sulfide Ore and Flotation Process

2019-7-9  1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.

What is Sulfide Mining? Mining Action Group

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water
