A Review Of Froth Flotation Control

A Review Of Froth Flotation Control

Sep 14, 2011· 1. Introduction. Froth flotation is one of the most broadly used separation methods in the mineral processing industry. However, despite being introduced in the early 1900s and numerous years of research and development, flotation is still not fully understood and remains relatively inefficient.

Flotation Process | Infoplease

flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore. Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.

8.6.1 Froth Flotation. There are various methods available for cleaning fine coal, of which froth flotation has become the most common practice. Froth flotation depends on differences in surface properties between coal and shale. Air bubbles are generated within an aqueous suspension of fine raw coal with a solids concentration of less than 10%.

Froth flotation is one of the processes used to recover recycled paper.In the paper industry this step is called deinking or just flotation. The target is to release and remove the hydrophobic contaminants from the recycled paper. The contaminants are mostly printing ink and stickies.Normally the setup is a two stage system with 3,4 or 5 flotation cells in series.
