Froth Flotation Method JXSC Machine. The froth flotation method is widely used to treat various veins of gold and silver ores for the following reasons 1 In most cases, the froth flotation process can enrich gold and silver in sulfide concentrate to the greatest extent and discard a large number of tailings, thus reducing the smelting cost.

Froth flotation is a process that selectively separates materials based upon whether they are water repelling hydrophobic or have an affinity for water hydrophilic. Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.

1 Froth Flotation Fundamental Principles. A typical flotation column is shown in Figure 13. The basic principle of column flotation is the use of countercurrent flow of air bubbles and solid particles. This is achieved by injecting air at the base of the column and feed near the midpoint. The particles then sink through a rising swarm of air.

The role of collector chemistry as the primary initiation step of the highly complex froth flotation process is widely acknowledged. While there have been advances in both the fundamental understanding of how purified collector reagents work in idealized tests, and in the improved plant scale use of commercial reagents by better dosage control, improved circuit configuration and control, etc.
