Chilean copper oxide ore flotation case
Copper oxide ore flotation technology can be divided into direct flotation and sulfide flotation. Direct flotation is the direct flotation of minerals with fatty acids and their soaps, advanced xanthate and other collectors without pre-vulcanization, including flotation of fatty acids, amines, emulsions and chelating agents.

Froth flotation is a method of separating ores using the difference in physical and chemical properties of mineral surfaces. It is currently the main method for the flotation of copper oxide. Relatively speaking, froth flotation can be used to separate malachite and azurite. However, chrysocolla and copper phosphate are difficult to float.

Direct Flotation Of Copper Oxide Ore
Direct Flotation Of Copper Oxide Ore Copper oxide ore is used to refine copper oxide. Copper oxide ore is produced in the Philippines, Pakistan and other regions. The monthly supply is about 1,000 tons to 2,000 tons. Copper oxide (CuO) is a black oxide of copper. The most common on the market today is 98% copper oxide and 99.95% copper oxide.

Abstract: Complex and refractory copper oxide ore is characterized by high oxidation rate, high binding rate, and complex mineral composition, making it extremely difficult to beneficiate. Malachite is a typical copper oxide ore. It will attract the dipoles of water in the slurry to form a oriented hydrophilic hydration film, which is not conducive to flotation.

Development and optimization of mixed sulphide/oxide copper ore
This conventional flow sheet incorporated the use of xanthate flotation of the sulphide minerals, followed by acid leaching of the oxides. The traditional method applied for the flotation of copper oxide or mixed ores is sulphidization, which was first developed with industrial success on Pb-Zn oxide ores in Australia (Crozier, 1991).
