Effects of Pyrite Texture on Flotation Performance of ...

Oct 18, 2021  Pyrite particles, having framboidal/altered texture, are known to significantly affect pulp chemistry and adversely affect flotation performance. Therefore, the main objectives of this study were to demonstrate influence of pyrite mineralogy on the flotation of copper (sulphidic) ores and develop alternative conditions to improve the performance.

The Flotation of Pyrite using Xanthate Collectors

Oxidation of pyrite in air showed a marked effect on the flotation properties of pyrite. In alkaline surroundings the recoveries were reduced by 30%. This effect was not observed during flotation in acidic solutions, since in situ leaching was taking place thus removing

Can you list the factors affects the floatability of pyrite from refractory low grade ore. I used a Wemco lab flotation cell and aimed on analysing factors like collector dosages (PAX), Activator (Copper sulphate),MIBC , pH and others like pulp density and particle size (70 and 150 microns) .However how these factors affect the floatability of the pyrites from low grade refractory ore.

Jan 01, 1991  Abstract. The objective of this project is to conduct extensive studies on the surface reactivity of pyrite by using electrochemical, surface analysis, potentiometric and calorimetric titration, and surface hydrophobicity characterization techniques and to correlate the alteration of the coal-pyrite surface with the efficiency of pyrite rejection in coal flotation.

Flotation separation of chalcopyrite from galena using ...

Nov 22, 2021  Recently, Shen et al. studied the role of LBG in the flotation separation of chalcopyrite and pyrite. Experimental analysis revealed that the acid/base interactions, hydrogen bonding, and the attraction between the hydrophobic parts of both LBG and pyrite surfaces were the potential forces that drove the adsorption of LBG on pyrite.

Feb 01, 2021  The variation in pH and ORP during the bioleaching process is shown in Fig. 1a. The pH of the bioleaching solution decreased dramatically (from pH 2.00 to 1.33) during the first 20 days of the experimental period, likely due to the release of large quantities of H + by bioleaching reactions, resulting in the sulfur moieties of pyrite and sphalerite being oxidized to sulfuric acid.
