Types and Price of Flotation Machine
The Introduction of Flotation Machine. Flotation machine, also called flotation cell, is the equipment to complete the flotation process. It is widely used for the rough, fine and reverse flotation operations of copper ore, lead ore, zinc ore, nickel, molybdenum and other non-ferrous metal, ferrous metal and nonmetal minerals.
The future of flotation
Unfortunately, the conventional flotation cell achieves high recovery only in limited size ranges. For example, a sulfide ore might float very well at 90 to 120 microns, but not at 50 or 150 microns.
Recovering Gold through the Froth Flotation Process
However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold's hydrophobicity.
