Science Desk: How SulfideOre Copper Mines Pollute | Save ...
May 08, 2015· No matter the method, sulfideore 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 metalbearing ore and waste rock. In the mine's first years, million tons of waste rock will be stockpiled on the surface while the mine is hollowed out.

Copper Environmental Profile
Primary copper production starts with the extraction of copperbearing ores. There are two basic ways of copper mining: surface and underground mining. Due to copper being spread in relatively low concentrations over large areas, surface, or openpit mining, is the predominant mining method for copper in the world.

How Are Metals Extracted From Their Ores? |
Full Answer. Copper ores generally contain sulfides or oxides and copper in the to percent range. Because of the greater value of copper metal, refining ores at these levels is profitable. Refiners crush copper sulfide ores mechanically and use froth floatation to bring coppercontaining particles to the surface of a water solution.

Dec 17, 2016· The ore is then crushed into finely ground tailings for processing with various chemicals and separating processes to extract the final product. In Canada on average for every tonne of copper extracted 99 tonnes of waste material (made up of soil, waste rock and the finely ground "tailings") must also be removed.

Copper Production: How Is Copper Made? The Balance
Sep 26, 2019· Virtually all sulfidetype copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting. After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic.

About 450 million metric tons (500 million tons) per year (1) of mill tailings are generated from copper, iron, taconite, lead, and zinc ore concentration processes and uranium refining, as well as other ores, such as barite, feldspar, gold, molybdenum, nickel, and silver. Mill tailings are typically slurried into large impoundments, where they gradually become partially dewatered.
