Jul 01, 2004· However, if theflotationrecoveries of gold andsulfideare unsatisfactory, reverseflotationof the carbonate minerals is a possible alternative. In this study, calcite and dolomite were used as representative carbonate minerals, and pyrite and chalcopyrite as representativesulfideminerals to study the feasibility of the reverseflotation.

Apr 01, 2019· Abstract. Theflotation separation of molybdenite from copper sulfide minerals (mostly chalcopyrite) typically relies on the use of toxic inorganic depressants such as cyanides and sodium sulfide/hydrosulfide. In this work, a nontoxic, biodegradable and cost-effective derivative of the natural polysaccharide chitosan, O-Carboxymethyl chitosan (O-CMC), is investigated as an alternative …

Jan 01, 2018· Flotation results indicated thatcopper ions dramatically reduced the recoveries of copper and molybdenum, and increased the inhibition effect of sodium sulfide; that is, the flotation separation of chalcopyrite and molybdenite was seriously hindered by copper ions.

Sep 01, 2020· On the other hand,sodium sulfide and sodium hydrosulfideare common inorganic inhibitors of Cu-Mo flotation separation, which are cheap and widely used in practical production. However, there are still some challenges, such as large dosage and poor stability.

Flotation separation of Feinstein based on thedifference in physico-chemical properties of sulfides of copper and Nickel - chalcocite (Cu 2 S) and heazlewoodite (Ni 3 S 2). Source Feinstein is ground in ball mills, then served in the hydrocyclone classifier and classifier defined …

Oct 27, 2020· A singlesulfideore is mostly processed by forthflotation, and the whole process includes crushing, grinding, classification, and forthflotation. Under the appropriate grinding fineness and agent system, from the raw ore with a Cu content of 0.77%, a concentrate with a Cu grade of 23.86% can be obtained, and the recovery rate is 95.24%.

The invention discloses aflotation separationmethod of antimonysulfideand gold-bearing pyrite. Sodium hexametaphosphate is adopted as a dispersing agent, sodium silicate is used as a silicon and calcium gangue inhibitor, copper sulfate is used as an antimony and gold mineral activating agent, butyl xanthate is used as a collecting agent, and No. 2 oil is used as a foaming agent, so that ...

This invention provides a process for improvedseparationof mono/multi-metallicsulphideminerals from significant amounts of iron sulphides, mainly pyrrhotite and/or their finely divided process middlings. The process comprises subjecting such material to a conditioning stage with at least one water-soluble sulphur-containing inorganic compound as a prerequisite step for further conditioning ...

Simplified flow sheets of representativeflotationplant operations are given to illustrate how these principles are applied for the commercialseparationofsulphideminerals from their ores. Various novel techniques that take advantage of controlling the electrochemical and physical behavior of theflotationsystem are also presented.

For coppersulfideore, when it uses xanthate as a collector, it has the best floatability, but usually a lot of inhibitors are needed to suppress it. 2.Copper-molybdenum mixed concentrateseparationprocess . For theflotation separationof copper-molybdenum mixed …
