MINING, TAILING & CONCENTRATE
In the Mining, Tailing & Concentrate sector, the filter press is used for both tailing and mineral concentrate recovery.
Coal mines, for example, need to dispose of coal mining by-products and thanks to Matec machines they can dewater the fine waste material suspended in water, recovering it, purifying the water and eliminating the need for sludge storage sites.
The Matec filter press is also used in concentrate recovery. For this application, the final cake must have a very low percentage of residual moisture, 6 or 7%. Matec filter presses are able to achieve this result through the installation of membrane plates that can further squeeze the already dry cake and the Cake Dryer accessory that, through the introduction of high-pressure hot air, allows residual moisture percentages close to zero to be reached.
