Best Chemicals for Froth Flotation
Frothers are good chemicals used in the floatation process of both metallic and non-metallic minerals. They effectively extract iron sulfide, non-sulfide minerals, copper, lead, and zinc. They are mostly made up of terpene derivatives and monohydric alcohols. The most common Frothers are Pine oil, CC903, and CC321. Chemical application of Frothers

Froth Flotation and Gold Extraction
Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water). Since its discovery, froth flotation has been a major component for the processing of sulfide-rich ores, including copper, coal, and refractory gold.

Explain froth flotation process of copper pyrites.
Solution. Copper is extracted from copper pyrites by froth flotation process. Froth flotation method is used to separate particles based on the differences in the ability of air bubbles to selectively attach to specific mineral surfaces in a mineral-water slurry. A finely crushed ore is suspended in water and a blast of air is passed through ...

Extraction of Copper from Sulfide Copper | MiningPedia
The mixed-priority flotation process is suitable for the extraction of copper from dense massive sulfide ore and disseminated sulfide ore with a non-sulfide content of more than 10-15%. The process flow is shown in the figure below. Most of the gangue is discarded in the mixed flotation circuit, so the copper concentrate grade can be improved.

Copper extraction
The modern froth flotation process was independently invented in the early 1900s in Australia by C.V Potter and around the same time by G. D. Delprat.
