Radio Hill in Australia successfully used the Ausmelt reagent AM28 (an alkyl hydroxamate) to float mixed sulphide/oxide copper ore, increasing recovery from a low of 40 to 50% up to 70%. They used AM28 to replace sulphidisation of oxide minerals, in conjunction with standard sulphide collectors to recover sulphide minerals.

Flotation of mixed copper oxide and sulphide …

The ore mined is from a primary copper sulphide deposit with separate additional deposits of copper oxides. In conjunction with Ausmelt Chemicals, Minto is currently investigating options to recover copper oxide and sulphide minerals using flotation by blending their primary sulphide ore with oxide ores.

Copper Ore - an overview | ScienceDirect Topics

From plant practice, treating oxide copper and copper cobalt ores, two basic flotation methods are practiced: (a) sulphidization flotation method, and (b) anionic flotation method. 19.5.1 Sulphidization flotation method. This method is the most commonly used in beneficiation if oxide copper-bearing ore.

Flotation of oxide copper ore with sodium oleate from the ...

Oxide copper ore flotation with 800 g/ton sodium oleate at pH 9 yielded 14.4% Cu with 83.3% recovery in a rougher circuit. To enhance the flotation performance, in terms of %Cu, optimum dosages of sodium silicate, quebracho, and pine oil were examined.

A New Application For Flotation Of Oxidized Copper Ore

In this study, the flotation of oxidized copper ore obtained from Ergani Copper Mining Company in Turkey was performed. This ore contains 2.03% copper, 0.15% cobalt and 3.73% sulfur. An effective processing method has not been found to recover copper and cobalt from this ore, which has been stockpiled for 40-45 years in the idled plant.

Types of copper ore: Oxides. As mentioned, copper oxide ores are not as attractive an exploration target as copper sulfide ores due to their lower grade. However, in some cases low-grade copper ...

Copper extraction - Wikipedia

Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. In some cases, tailings have been retreated to recover lost value as the technology for recovering copper has improved.

Abstract: The copper oxide ore in Dali, which contains 0.69% of copper and 11.24g/t of silver, was beneficiated by sulphidizing - xanthate flotation method. The flotation tests were carried out systematically with sodium sulfide as sulphidizing agent and butyl xanthate + ammonium dibutyl dithiophosphate as the combined collectors.
