Frothers | Quadra

Frothing, also known as froth flotation, is the process of selectively separating hydrophobic valuable minerals from hydrophilic waste gangue. In its simplest form, froth flotation is a method whereby minerals can be "skimmed" from the surface of "slurry" that is "ed" with the assistance of specific chemicals, water and air bubbles.

Separating Minerals by Floatation

Air injected into the floatation cells, along with ing agents, creates a bubbly froth. An added chemical called a collector acts on the lighter mineral, causing it to attach to bubbles and rise to or near the surface. The float material then overflows or is skimmed off, while the bottom material goes on to another separation process or to ...
