Dec 20, 2018 The flotation of gold and silver minerals is mostly carried out in alkaline pulp medium, but for some goldbearing pyrite and pyrrhotite, it is suitable for flotation in weak acid

The flotation of mineral ores is a process that has been refined for more than 120 years. Since the early 1990's BOC has investigated the use of gases such as oxygen, nitrogen and CO 2, in the mineral processing industry.The application of our gases changes the hydrophobicity and hydrophilicity of the surface characteristics of the ore particles.

Copper extraction. Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide usually chalcocite, which can then be activated by the froth flotation plant Sulfide smelting

1. Effective flotation of titanium and zirconium minerals is achieved with an oxygen content in pulp of 8–10 mgliter under normal conditions. 2. A higher than the normal oxygen concentration in pulp increases the rate of flotation for all titanium and zirconium minerals; a lower than the normal concentration slows it down.
