Role of Sodium Hydrosulfide in Flotation
Sodium hydrosulfide can sulfurize the surface of partially oxidized sulfide minerals, restoring their floatability. It reacts with the oxidized mineral surface to form a sulfide film, enhancing the hydrophobicity of the mineral surface.
It serves as a modifier in the separation of sulfide and oxide minerals by suppressing the flotation of oxide minerals. This occurs through the formation of a hydrophilic film on the oxide mineral surface, preventing collector adsorption.
