Copper Oxide Flotation Mineral Processing & Metallurgy

Continuing with the evaluation of copper oxide flotation using hydroxamate we now evaluate a rock that’s 41% copper oxide with some lead oxide included. Sample B: 1.8% Copper about 41% Oxide Cu Rougher Tests: Unseen in these charts is the order in which the results were obtained. The last/best “Blue” dot (the best data point) was the last test of the series. Oxflo’ selectivity

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. It was established that recovery of copper and cobalt from

Oxide Flotation Collector Collector for Copper Oxide Ore

In this flotation tests and evaluation for the best collector for copper oxide “ore” 911Metallurgy continues with material that’s 60% Oxide copper. Sample C: 1.7% Copper about 60% Oxide Cu Rougher Tests: Both reagents appear to behave similarly as the “blue dots” are seemingly a continuation of the trend started by “red dots”. Oxflo and Axis show that the more %Mass you recover

RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION

At those years in the past, at one of the Soviet plants, 1% copper containing oxide copper ore was floated with a recovery of 80% and a copper grade of 19%. Wills (2006) mentioned that oxide cap of primary copper deposits can be mined selectively and successfully processed by froth flotation.

Studying on Oxide Copper Ore Flotation with Different

01/08/2014· Various collectors and combinations of them were used for experimental study on flotation of oxide copper ore in Huidong and the results showed that isoamyl xanthate would be a proper collector agent. When using it at 550g/t, the rough concentrate grade was 3.97%, and the recovery rate reached its highest value of 83.05%.

The recovery of oxide copper minerals from a complex

01/03/2017· 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

Copper Oxide an overview ScienceDirect Topics

17.8 Flotation of Oxide Copper–Gold Ores. Oxide copper–gold ores are usually accompanied by iron hydroxide slimes and various clay minerals. There are several deposits of this ore type around the world, some of which are located in Australia (Red Dome), Brazil (Igarape Bahia) and the Soviet Union (Kalima). Treatment of these ores is difficult, and even more complicated in the presence of clay minerals.

Selective Flotation of Copper Oxide Minerals with A Novel

20/03/2019· The bench-scale flotation outcomes showed that TMATT achieved the high-efficient flotation separation and enrichment of copper oxide minerals from the mixed sulfide-oxide copper ore. XPS, FTIR, AFM, and zeta potential deduced that the adsorption of malachite toward TMATT was related to the reduction of surface Cu(Ⅱ) to Cu(Ⅰ) and the formation of TMATT-Cu(Ⅰ) surface complexes in

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. At the optimum dosages, the grade increased to 20.1% Cu with 76.4% recovery. To upgrade the rougher concentrate, sodium oleate was added in the

Copper Mining and Extraction: Oxide Ores

The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. The smelting stage gives the name pyroprocessing: processing by fire.
