Froth flotation Wikipedia

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.

Zinc Alloys: Properties, Processing and Applications

This process involves the ‘roasting’ of concentrated forms of zinc ore, the concentration of which is achieved via the froth floatation process. This concentrated ore is finely ground and suspended in a stream of air which serves the dual purposes of converting the ore into the highly reactive zinc oxide ZnO and also to reduce the sulphur

Flotation Process an overview ScienceDirect Topics

Iron oxide particles stick to the air bubbles and float. Floated and concentrated iron ore slurry is then skimmed from the surface of the bath, and water is removed using a filter press. If the desired iron content is not achieved, the process is repeated. A modifier is added in some cases to enhance the performance of the collector.

Crusher Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
