Depression of lead-activated sphalerite by pyrite via galvanic
In practice, chalcopyrite and galena are floated first followed by sphalerite, so activation of sphalerite by Pb 2+ is an unwelcomed side reaction because it dramatically limits the separation of these three sulfide minerals by selective flotation. Co-existing gangue sulfide minerals like pyrite are also known to strongly affect the floatability of …
1 Froth Flotation – Fundamental Principles
1 Froth Flotation – Fundamental Principles. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while ...

Solution Chemistry of Flotation | SpringerLink
Flotation occurs at the solid-liquid-gas three phase boundary, first of which is the interaction between the flotation agent and minerals in the pulp. Therefore, the flotation system is based on inorganic chemistry, organic chemistry, analytical chemistry, and surface chemistry. Early flotation researchers used this basic chemical knowledge …
Understanding the effect of sulphate in mining-process …
Formation of calcium sulphate (gypsum) by the interaction of calcium ions with sulphate ions in the pulp produces fines slime coatings on the sulphide minerals and hinders the flotation of the desired minerals ( Raghavan and Hsu, 1984, Grano et al., 1995, Zanin et al., 2019 ). Sulphate may also increase capital expenditure because of its …
