Generally, three basic methods of flotation of oxidized Cu ores are used: 1. Flotation after previous sulphidisation of the surface of Cu oxide minerals. 2. Direct flotation of …
The traditional method applied for the flotation of copper oxide or mixed ores is sulphidisation, which was first developed with industrial success on Pb–Zn oxide ores in Australia (Crozier, …
oxide copper in a ore can be taken as a important criterion of floatability of the ore. To determine combined oxide copper in ores, a chemical analytical procedure termed phase analysis has …
In this paper, we have reviewed the surface properties of common copper oxide minerals and summarized application of direct flotation, sulfidization flotation, and activation …
Oxide copper mineral deposits contain varying amounts of chrysoeolla, and poor copper recoveries are generally associated with the lack of flotation response from this mineral. Of the …
Copper oxide minerals are important copper resources, which include malachite, azurite, chrysocolla, cuprite, etc. Flotation is the most widely used method for the enrichment …
Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water …
The process involves two basic flotation methods: (a) fatty acid flotation of oxide copper minerals from siliceous ore, and (b) sulphidization of oxide copper minerals followed by flotation using …
Abstract—An analysis of flowsheets for processing sulfide and oxide copper ores, reagent modes, processing equipment, and flotation indicators in some domestic and foreign …
Flotation of sulphidic and oxidic copper minerals is reviewed, with particular reference to previous studies of refractory copper ore flotation.
