Dithiophosphates are available as water-soluble salts that exhibit a wide range of properties with respect to selectivity and froth character. Dithiophosphates are effective in alkaline flotation circuits and are more selective than xanthates. Monothiophosphates (MTPs) are effective copper collectors in acid circuits and help improve gold recovery.

Sep 13, 2017· It's a very cost-effective method for concentrating gold, and is a desirable process used for the upgrading of low-sulphide and refractory ore for further gold recovery treatment. Froth flotation is a process used to selectively separate hydrophobic materials from hydrophilic materials.

A conceptual model for gold flotation - ScienceDirect

The flotation recovery of free gold is largely affected by physical constraints like the shape and size of the particles, the degree of water and gangue transport to the froth, the stability of the froth, and the extent of bubble loading of sulphide particles which can provide a barrier towards the hydrophobic bubble attachment of free gold.
