Froth flotation explained.Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries.Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

In this work, a fundamental study was carried out on the role of surfactants in bubble-algae interaction to improve the understanding of how surfactants influence the flotation performance.
Get PriceLime use and functionality in sulphide mineral flotation.Sulphide ores are the major source of valuable metals such as copper, lead, zinc, and nickel, as well as gold, silver, and platinum group metals pgms, and flotation is the dominant industrial process to recover these metals via the production of a sulphide concentrate.Cited by 1.
Get PriceFroth 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.
