Surface chemistry investigation of froth flotation

1. Introduction. In the mineral processing industry, lead-zinc sulfide ores are usually processed by froth flotation to enrich the purpose minerals .Flotation is a complex process, and the selective separation of minerals depends on the balance between the hydrophilic species and hydrophobic species on the mineral surface,.Mineral surface species are influenced by many factors, such as

Starch chemical modification for selective flotation of

Sep 01, 2020· Other parameters worth mentioning are pH, dissolved oxygen (DO) and redox potential (Eh) which control chalcopyrite flotation behaviour through affecting mineral surface reactions in many different ways (Güler et al., 2009). An example is shown in Fig. 2 on how potential (Eh) influences the flotation of sulphide minerals.

Flotation separation of carbonate from sulfide minerals, I

Jul 01, 2004· In these tests, a carbonate mineral was blended with a sulfide mineral at 1:1 weight ratio and floated using similar procedures as in single mineral flotation tests. At the end of the flotation, the grades of the concentrates and tails were determined by measuring the Ca, Mg, Fe or Cu contents using atomic absorption spectroscopy.

Slurry Treatment and Flotation Reagent Selection of Non

Flotation of non-sulfide minerals is more difficult than that of sulfide minerals. The main reason is that non-sulphide ores usually have high water solubility, and the useful minerals and gangue minerals are usually of similar types, with a small difference in surface properties.

Mining Industry Copper Sulfide Ore and Flotation Process

Other copper sulfide minerals, such as covellite (CuS), are similar in floatability to chalcopyrite. The buoyancy of tetrahedrite (4Cu2S·Sb2S3) and tennantite (4Cu2S·As2S3) is similar to that of chalcopyrite. 3 Summary of the copper mineral flotation process (1) Copper minerals (such as chalcopyrite and covellite) that do not contain iron are

Effect of pH on Pulp Potential and Sulphide Mineral Flotation

Control of pH is one of the most widely applied methods for the modulation of mineral flotation. In this study the effect of pH on potential in solution and sulphur minerals flotation is discussed with various electrodes. The electrodes were platinum, gold, chalcopyrite, pyrite and galena. In solution, potentials were linearly dependent on pH with a different slope for each electrode.
