Gold with transition elements, such as silver (goldsilver alloy), copper (copper aurides) and iron are common in most of the hypogene and altered coppergold ores (i.e. supergene). The distribution of gold in an ore plays an important role in the selection of the type of flotation process that can be applied to recover the gold [34].

Flotation Froth an overview ScienceDirect Topics

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.

Introduction to Mineral Processing  Chevron Phillips Chemical

Introduction to Mineral Processing Chevron Phillips Chemical

In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer. Sulfide and nonsulfide minerals as well as native metals are recovered by froth flotation.

Froth flotation

Froth flotation

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

Dissolved Air Flotation Process in Wastewater Treatment

Dissolved air flotation (DAF) is a water treatment process for removing oils, solids, and greases from a water supply. The process helps clarify wastewaters by eliminating different types of suspended matter. DAF dissolves air in pressurized water then releases it at atmospheric pressure.

In flotation, the technician places dried soil on a screen of mesh wire cloth, and water is gently bubbled up through the soil. Less dense materials such as seeds, charcoal, and other light material (called the light fraction) float up, and tiny pieces of stone called microliths or microdebitage, bone fragments, and other relatively heavy materials (called the heavy fraction) are left behind
