Flotation - an overview | ScienceDirect Topics

Flotation is widely used to separate valuable minerals from the rock and fine coal particles from clay, silt, shale, and other ash-producing matter. It is usually preceded by crushing and finely grinding the ore to liberate valuable particles in a host rock, and may be followed by metallurgical processes.

Deinking - Wikipedia

Deinking is the industrial process of removing printing ink from paperfibers of recycled paper to make deinked pulp. The key in the deinking process is the ability to detach ink from the fibers. This is achieved by a combination of mechanical action and chemical means. In Europe the most common process is froth flotation deinking.
