The most reported polymeric depressant is carboxymethyl cellulose (CMC), which has been widely used for depressing MgO-type gangue minerals in nickel sulfide

Novel depressants for depressing sulfide minerals during froth floatation of ores to recover value minerals are disclosed, as well as a method for their use in the froth flotation. The novel depressants are terpolymers of a (meth)acrylamide, an allyl thiourea and a hydroxyalkyl (meth)acrylate

The purpose of this research is to investigate the depression effect of two polymeric depressants (S-7260 and S-7261) developed by Cytec Industries by conventional flotation technique, and the possibility of replacing DETA with cheaper polymer depressants in pentlandite pyrrhotite flotation separation. 3.3 EXPERIMENTAL 3.3.1 Mineral Samples

Problem: A copper ore initially contains 2.09% Cu. After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate: (a) Ratio of concentration (b) % Metal Recovery (c) % Metal Loss (d) % Weight Recovery, or % Yield (e) Enrichment Ratio

Nov 20, 2018 The bench-scale flotation results show that using acidified water glass in conjunction with locust bean gum is suitable in the flotation of a refractory copper sulfide ore that contains multiple MgO gangue minerals, and a copper concentrate with grade of 20.25% and recovery of 75.8% is achieved when the feed ore copper grade is 0.16%

Flotation of cobalt sulfide ores can be best achieved at acidic pH (~. 4) with xanthate collectors and at pH of about 7.5 for oxide ores with nitrosonaphthol chelating reagents, while their

Sulphide ores are the major sources of base metals like Copper, Lead, Zinc, Nickel and Cobalt. Beneficiation of. these base metal sulphide minerals is predominantl y through the froth flotation

Reagent 425 A yellow to greenish yellow hydroscopic powder. 5% solution .2 to .5 Developed primarily for flotation of oxidized copper ores. Promoterfor malachite and azurite without sulphidization. Reagent 444: A yellow water soluble powder

Talcum is a common gangue with which sulphide ores are associated, it has an adverse impact on sulphide ores flotation and product index due to its high natural floatability. In this paper it takes talcum-bearing copper sulphide ores from DongChuan in Yunnan province as experimental samples, and a series of tests on depressing talcum in the copper suphide ore flotation were carried out

Jan 26, 2021 Pyrite depression in the flotation of copper ores is difficult due to the activation of Cu2+ ions on pyrite surface. In this study, the radical chain reaction involving the redox cycling of Cu(I/II) induced by sodium metabisulphite (MBS) was exploited to selectively depress the flotation of copper-activated pyrite at pH 8.0. Electrochemical measurements revealed that the presence of Cu2+ and
