Copper extraction - Wikipedia

Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide (usually chalcocite), which can then be activated by the froth flotation plant. Sulfide smelting

Hydrogen sulfide - Wikipedia

Hydrogen sulfide is a chemical compound with the formula H 2 S.It is a colorless chalcogen hydride gas with the characteristic foul odor of rotten eggs. It is poisonous, corrosive, and flammable. Hydrogen sulfide is often produced from the microbial breakdown of organic matter in the absence of oxygen, such as in swamps and sewers; this process is commonly known as anaerobic digestion which is ...

Froth Flotation Process - Mineral Processing & Metallurgy

Jan 20, 2021· “The single most important method used for the recovery and upgrading of sulfide ores”, that’s how G. J. Jameson described the froth flotation process in 1992. And it’s true: this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different categories of hydrophobicity that are increased by ...

How copper is made - material, used, processing, steps ...

Most of the copper ores mined in the United States contain only about 1.2-1.6% copper by weight. The most common sulfide ore is chalcopyrite, CuFeS 2 , also known as copper pyrite or yellow copper ore. Chalcocite, Cu 2 S, is another sulfide ore. Cuprite, or red copper ore, Cu 2 O, is an

Copper production & environmental impact - Greenspec

Sulfide ores and froth flotation. Sulfide ores are mixed with water and a surfacant creating a slurry. The slurry, when agitated causes the copper sulfide minerals to float at which point they are skimmed off the surface dried. The dried material is then sent to the smelter. Oxide ores and leaching
