Abstract Copper oxide minerals are important copper resources, which include malachite, azurite, chrysocolla, cuprite, etc Flotation is the most widely used method for the enrichment of copper oxide minerals in the mineral processing industry In this paper, the surface properties of copper oxide minerals and their effects on the mineralFatty acids have also commercially been used in the flotation of oxide copper minerals from siliceous ores, where “copper oxide” is a generic term for nonsulfide copper minerals In contrast to iron oxides, the adsorption of fatty acids on Cu oxides is typically explained in terms of chemisorption [ 21,22 ], though, to the best of our EcoFriendly Collectors for Flotation of Fine Hematite and
Copper extraction
Generally, direct froth flotation is not used to concentrate copper oxide ores, as a result of the largely ionic and hydrophilic structure of the copper oxide mineral surface Copper oxide ores are typically treated via chelatingreagent flotation and fattyacid flotation, which use organic reagents to ensure adsorption onto the mineral surface through the Copper hydrometallurgy the leaching of siliceous lowgrade copperbearing ores and waste rock that cannot be processed economically by milling and concentrating is an important lowcost process for recovering copper In the free world, the United States is the principal user of this process, and in 1965 nearly 10 percent of the US production of Copper Hydrometallurgy
