Recovery Cu from a Copper Oxide Ore by Flotation and ...
The copper oxide ore is high oxidation ratio and the high combination ratio with a low grade of Cu 0.71%. Copper concentrate of Cu 15.02% with a recovery of 38.55% was obtained by flotation. The optimum acid leaching conditions were investigated. Effects of lixiviant concentration, solid-to-liquid ratio, leaching time were investigated. The acid leaching efficiency was 78.75% relative to ...

2021-5-1 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 Copper oxide ore - Fodamon Machinery
For example, when copper is in the form of carbonate (malachite, blue copper ore), the flotability is relatively good, while the flotability of silicate (silica malachite) is poor, free copper oxide is easy to float, and copper oxide can not be recovered by a single flotation method. Copper oxide minerals in a separate state are called free copper oxide.

The recovery of oxide copper minerals from a complex ...
2017-3-1 The oxide ore has a much higher grade than the mixed and sulphide ores but contributes less to the resource (Broughton et al., 2002). The preferred method for the flotation of oxide and mixed copper ores is sulphidisation. The reagents are typically sodium sulphide (Na 2 S) and sodium hydrosulphide (NaHS). Slug sulphidisation, which uses a single slug dose, is generally not preferred because the difficulty in controlling the pulp potential leads to poor mineral recoveries

In this study, the effects of important factors on malachite exploited from Tibet are investigated. Dosages of activating agents, depressants and collectors are essential to the effective recovery of copper in the flotation. The mixed collector ratio of SIBX: Armac C was varied as 0:1, 1:1, 1:2, 1:3, and 1:4. This investigation showed that using Armac C in conjunction with traditional SIBX ...

Copper oxide ore has a complex composition, and a low recovery rate is often achieved via the traditional sorting method. A new combined process of flotation–high-gradient magnetic separation–leaching is proposed here to recover copper minerals. The test results showed that the flotation process was successful when using sodium sulfide as a vulcanizing agent and butyl xanthate as a collector.
