These proven technologies are designed to achieve your objectives quickly and efficiently and provide you with flotation options to increase your profitability.
Flotation columns work on the same basic principle as mechanical flotation cells – mineral separation takes place in an agitated and/or aerated water mineral slurry where the surfaces of selected minerals are made hydrophobic (water-repellent) by conditioning with selective flotation reagents. However, in column flotation, there is no mechanical mechanism causing agitation. As well, separation takes place in a vessel (known as a column) that is much taller than the width (or cross-section) of the cell. Air is introduced into the slurry in the column through spargers, which create a countercurrent flow of air bubbles.
Compared to traditional mechanical cells, column flotation is slower, but it allows for improved kinetics.
Column flotation offers many advantages including:
The flotation contact cell is a slurry aeration device with no moving parts. The contact cell consists of two main components:
The contact cell is mainly used in rougher flotation circuits. It is compact, highly efficient, simple to operate, and has low energy and maintenance costs. There are a number of other benefits and capital savings that can be obtained when installing contact cells including:
SGS is the most experienced and trusted organization in the mineral processing industry. We have conducted flowsheet design and pilot plant testing on thousands of flotation projects. Let our experts improve your flotation performance with our proven column and contact cell technologies.
