Flotation of sphalerite and pyrite in the presence of sodium sulfite

Pyrite is one of the major diluents of copper, lead and zinc concentrates. One explanation for the high flotation of pyrite in alkaline pH conditions is its inadvertent activation by copper either dissolved from copper minerals present in the ore or added in the zinc

Reverse Flotation | IntechOpen

11/10/2017· Reverse flotation of coal can be explained as a process where valuable minerals are depressed, while undesired and unhealthy minerals are floated with the help of some reagents. Nowadays, conventional enrichment method of coal could not achieve removing unhealthy minerals partially from internal structure of coal such as sulfur, Hg, Au, which propagate in air after burning

THE ROLE OF COPPER IONS IN SPHALERITE-PYRITE

An important practical example is the misplacement of pyrite to zinc concentrates. Flotation of sphalerite generally requires activation by copper ions, added as copper sulphate. Copper ions are also used to activate pyrite [Voight et al., 1994] hence there is the
