Study of galvanic interactions between pyrite and ...

Aug 15, 2006· When galvanic interactions between pyrite and chalcopyrite occur in solution, pyrite, with the higher rest potential, acts as a cathode and is protected whereas chalcopyrite, with the lower rest potential, acts as an anode and its oxidation is increased. In this work a three-electrode system was used to investigate the corrosion current density and mixed potential of a galvanic cell comprising ...

The Critical Role of Pulp Density on Flotation Separation ...

A nickel-copper sulfide system usually coexists with serpentine in deposits. Low nickel-copper recovery and high content of serpentine in concentration adversely affects subsequent metallurgical processes. In this study, test data showed different rheological results at various densities. When the solid ratio of sulfide to serpentine was 1:1, lower pulp density (20 wt %) contributed to better ...

Flotation features of fluorapatite with ricinoleic acid ...

Jan 04, 2021· Improving the collecting ability of a collector is a crucial issue in phosphate flotation. In this work, ricinoleic acid (RA) was used as a collector for fluorapatite (FA, Ca5(PO4)3F) flotation. There is an OH group in the middle of the RA molecule, and thus, hydrogen bonds (H-bonds) can be formed between RA species. The role of the H-bond between RA molecules in FA flotation was revealed by ...

Flotation is an important and vital method to separate valuable minerals from gangue effectively (Chandra et al., 2009). Many researchers have proved that flotation is an efficient technique to concentrate quartz (Wang et al., 2005; Mowla et al., 2008). It was studied by Larsen et al. (2015) that quartz could be floated in diluted solutions of
