what are the chemical can be used in flotation process

Safe Drinking Water is Essential: Coagulation

The process is often followed by gravity separation (sedimentation or flotation) and is always followed by filtration. A chemical coagulant, such as iron salts, aluminum salts, or polymers, is added to source water to facilitate bonding among particulates. Coagulants work by creating a chemical reaction and eliminating the negative charges that

Environmental Impact of Flotation Processing

Environmental Impact of Flotation Processing Valuable minerals in an ore can be separated from each other, and from worthless minerals, by the froth flotation process. The need for a process to extract ore arose from major sulfide mineralization after the oxide ores had been depleted.

Flotation Collector

Flotation fother, also called foaming agent, mainly acts on the water-air interface, which makes air diffuse into small bubbles in the slurry and can improve the bubble mineralization and the bubble stability during the floating process. While flotation frothers can adjust the chemical action between other agents (mainly collectors) and the

Copper

Copper and alloys with a high copper content are recycled to obtain pure copper. The metals are heated with oxygen-enriched air, which oxidizes most of the metals, but not the copper or any precious metals, forming a slag that can be removed. The Isasmelt process described above is often used for secondary copper production.

How zinc is made

2 Zinc can be produced by a process called froth flotation, which is also used for reduction of copper and lead ores. This process involves grinding the zinc ore to a fine powder, mixing it with water, pine oil, and flotation chemicals, and then agitating the mixture to float the zinc to the surface.
