Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.
DEC High Efficiency Flotation. The DEC Flotation column is a high efficiency flotation device which handles slurry feeds spanning a wide range of particles sizes and will float up to 1.5mm particles with ease, at high efficiency.
PrepQuip's in house designed Column Flotation are manufactured in South Africa and is supplied both locally and internationally. As a result of our extensive research and development as well as test work capabilities, PrepQuip is in a position to tailor-make both Conventional and Turbo-type Flotation Columns to suit individual applications for a variety of ores.

· The flotation column unit operation has fundamentally different hydrodynamic and contacting characteristics (ie counter current contacting of the ore particles with the bubbles and the wash water with the froth) than the conventional stirred tank flotation cell.
This book presents the analysis of a wide range of problems in the process theory of flotation columns, including the first published analysis of models of flotation froths.
COLUMN FLOTATION MODELLING AND TECHNOLOGY J.B. YIANATOS Chemical Engineering Department University of Santa Maria Valparaiso, 110-V, Chile ABSTRACT A brief review of the art of column flotation technology is presented. The flotation column characteristics are described, followed by an analysis of the principal variables
