Question

why collector molecules are added in froth Flotation process
​

Answer 1

Explanation:

• Collectors are reagents that are used to selectively adsorb onto the surfaces of particles. They form a monolayer on the particle surface that essentially makes a thin film of non-polar hydrophobic hydrocarbons. The collectors greatly increase the contact angle so that bubbles will adhere to the surface.

Answer 2

The surface properties of a mineral determine its ability to float. Collectors, some of the most important flotation reagents used in the flotation process, are used to modify the surface properties of minerals. ... Collector selection is critical for effective mineral separation via froth flotation.
