NEW AND USED FLOTATION FOR SALE. In gold mining, froth flotation is used to separate gold from gangue by utilizing gold’s hydrophobicity. Flotation uses bubbles that are introduced into a pulp and rise through the pulp. In the process, hydrophobic particles (gold and other minerals) become bound to the surface of the bubbles.
For sulfide ores, both secondary and primary,froth flotation is used to physically separate ore from gangue. For special native copper bearing ore bodies or sections of ore bodies rich in supergene native copper, this mineral can be recovered by a simple gravity circuit. Froth flotation
Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.
