chalcopyrite flotation process

Chalcopyrite Flotation without Collector Surface Chemistry

It has been reported that chalcopyrite can be floated selectively from an ore containing pyrite, sphalerite, and silicious gangue minerals without using a collector. Sodium sulfide was used as a promoter, presumably to clean the chalcopyrite surface of its hydrophilic oxidation products. Later it was found that the potential of the pulp, measured with a platinum-calomel electrode pair, was

Flotation separation of chalcopyrite from talc using a new

Both chalcopyrite and talc used for all experiments were collected from Yip’s Mineral Specimen Company. After being hammered, hand-selected, dry-ground, and screened, a sample of 38−74 μm fractions was prepared for micro-flotation studies and −38 μm fractions were collected for adsorption tests, zeta potential measurements and FTIR studies.

Activating flotation of chalcopyrite using CuSO4 and H2O2

activation mechanism of the flotation of cyanide chalcopyrite remains unknown. The flotation process is accompanied by a number of physical or chemical changes, such as the interaction and dissolution of reagents and mineral particles (Gao et al., 2017). The use of conventional

Mining Industry Copper Sulfide Ore and Flotation Process

The chalcocite is more oxidized than the chalcopyrite, copper ions enter the slurry, complicating the flotation process and increasing the difficulty of separating. The collectors of chalcopyrite are mainly xanthate and Aeroflot. The effective inhibitors are sodium sulphate, sodium sulfite, potassium ferricyanide and potassium ferrocyanide.

Flotation behavior of enargite in the process of flotation

Oct 01, 2019· The objective of this work is to study the behavior of enargite in the process of flotation using seawater. A comparison of the flotation of enargite and chalcopyrite using seawater is also carried out as the separation of these two minerals by flotation is a true technological challenge facing industry. 2. Materials and methods 2.1.
