Xanthates are used as a flotation agent and have a strong material collector effect. They are mainly used to enhance hydrophobicity of the mineral surface, leading to flotation.
Xanthates are commonly used in the flotation process of sulfide minerals, including copper, lead and zinc. Flotation involves separating the mineral particles as froth from the feed.
The molecular weights of Xanthates range from 140 to 200g and are supplied as water-soluble powders or pellets.
They are usually applied as 2% to 20% solutions and water solubility varies between 110 to 460 g/l, increasing at higher temperatures.
