Flotation Plant Equipment

If you would like to speak with us about Flotation Plant Equipment please Call Us at our Mining and Operations office and we will do our best to offer good advice and practical solutions.

Because a flotation plant requires both heavy financial and time investment HOLDTRADE works with and recommends FLSmidth, who have years of experience and specialised flotation equipment to provide excellent performance in two financially critical areas: Metallurgical recovery and flotation cell availability. WEMCO, EIMCO, and Dorr-Oliver flotation machines have earned global recognition for design innovations that deliver greater efficiency with dramatic power savings. Proven superior performance means that FLSmidth now supply over two thirds of the world's flotation cell equipment and won the contract to the largest flotation cells in the world, installed in 2003.

HOLDTRADE can leverage their strong relationship with this leading flotation equipment supplier together with our years of project management experience to ensure you have the flotation equipment to suit your needs at the right budget.

What is Flotation?

Flotation in mining is a process for concentrating the metal-bearing mineral in an ore. Uses include the cleaning of fine coal and the removal of contaminants from flint glass sand. During the process valuable mineral particles are induced to become attached to bubbles so they float, whilst other undesirable particles sink.

Flotation requires specially designed equipment to create these conditions.

Until recently flotation was almost completely dominated by the simple and reliable agitation type unit (the stirred tank). However, recent years have seen the re-evaluation of earlier novel flotation machines and new innovative designs. Their introduction has led to improvements in process economics, through savings in both capital and operating costs, as well as improved performance, grade and/or recovery.

If you require information or advice on flotation processes, please contact us and we can discuss your requirements and how we can help.

How Flotation Works

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. The waste material (gangue) settles to the bottom. The froth is skimmed off, and the water and chemicals are distilled or otherwise removed, leaving a clean concentrate. The process, also called the froth-flotation process, is used for a number of minerals, especially silver.

Concentrators

A full range of concentrators and concentrating equipment can be supplied. Please contact us for more information.
