    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.

  • Science Desk: How Sulfide-Ore Copper Mines Pollute Save

    Sulfide-ore copper mining is a risky type of mining that has never been done before in Minnesota. No matter the method, sulfide-ore copper mines proposed near the Boundary Waters would extract trace amounts of metals from large volumes of rock. Rock is blasted from pit walls and sorted into metal-bearing ore and waste rock. In the mine's first years, 4.1 million tons of waste rock will be stockpiled on the surface while the mine is hollowed out. The sulfide-bearing ore

  • Copper Sulfide Ore- Metalcess

    About 80% of the world’s copper-from-ore originates in Cu-Fe-S ores, such as chalcopyrite (CuFeS2) and chalcocite (Cu2S). The concentration of these minerals in an ore body is low. Typical copper ores contain from 0.5% Cu (open pit mines) to 1 or 2% Cu (underground mines). Cu-Fe-S minerals are not easily dissolved by aqueous solutions, so the

  • Copper Sulfide an overview ScienceDirect Topics

    The leaching of copper sulfide and copper oxide ores entails partial dissolution to cupric sulfate with sulfuric acid and iron sulfate. The presence of pyrites in many ore deposits, and its reaction with water and oxygen to form iron sulfate and sulfuric acid, creates an important source of acid. In dump leaching, the pH of the solution is maintained between 1.5 and 3.0, partly to preserve bacteria that promote and accelerate the oxidation of purity and copper

  • Copper Ore Types: Sulfides versus Oxides Nasdaq

    23.04.2011· Both ore types can be economically mined, however, the most common source of copper ore is the sulfide ore mineral chalcopyrite, which accounts for about 50 percent of copper production. Sulfide

  • Copper Mining and Extraction: Oxide Ores

    The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. The smelting stage gives the name pyroprocessing: processing by fire. (Courtesy of Xstrata.) The smelter for sulfide ores
