Sulphidisation followed by flotation is the preferred beneficiation technique for oxidised copper-cobalt ores. • The integration of CPS systems into the flotation circuits can help minimise reagent overconsumption. • Application of selective flotation can help a concentrator to produce separate oxide and sulphide concentrates.
This article gives the overall review of zinc oxide (especially smithsonite) beneficiation by different flotation reagents. The objectives of this investigation are to review zinc oxide flotation and to present a quantitative analysis of published data in this area. ... Role of sodium sulfide in the flotation of oxidized copper, lead and zinc ...
Beneficiation of Copper Sulfide by Flotation. Copper, due to the present world demand and price, is of foremost interest to the mining industry. Many new properties are either in the process of being brought …
The easy-to-select copper oxide ore mainly uses flotation, and the difficult-to-select copper oxide ore mostly uses a combined process. The flotation technology of …
A combined method of cleaning of copper–molybdenum ore beneficiation middlings which includes ore grinding to 72–75% of −74 μm size, flotation of sulfide minerals at рН of 10.3–10.5 and bacterial leaching of sulfide flotation tailings at рН from 2.1 to 2.3 at a temperature of 32–35 °C during 3 days and guarantees the total ...
From this review, it is clearly understood that copper flotation is the most extensively practiced beneficiation process. Primarily, the flotation of copper sulphide minerals was rigorously practiced using …
The beneficiation process of copper ore beneficiation plant is basically based on flotation. The flotation process of copper monosulfide ore is generally relatively simple. It is only different from complex copper sulfide ore in the grinding-flotation structure, which affects the beneficiation of copper ore.
The beneficiation of high talc-containing copper–cobalt flotation tailings was studied by centrifugal gravity concentration. It was found that copper and cobalt minerals were finely disseminated in the gangue matrix so that conventional gravity concentration using spirals and shaking tables would be ineffective.

The role of gold beneficiation reagents cannot be underestimated. More than 85% of the world's gold ore is mainly extracted by cyanidation. However, the use of a variety of reagents mixed and added into gold beneficiation is mainly to improve the effect of flotation gold selection. Gold beneficiation reagents are important auxiliary materials …
