How filter presses are used in the mining and mineral processing industries

A filter press is a versatile and efficient piece of equipment designed for separating solids from liquids. By applying pressure, it compacts slurry between filter plates, leaving behind dewatered solids and purified liquid.
One of the largest users of filter presses is the mining and minerals processing industry. The extraction of valuable minerals and metals from ore generates substantial quantities of slurry. Filter presses are used here to separate water from solid mineral residues, facilitating easier disposal or further processing. For example:
Tailings Management: Post-mining operations often leave behind slurry called tailings. Filter presses help reduce the moisture content of tailings, allowing mining companies to minimize environmental impact and comply with strict waste disposal regulations.
Concentrate Dewatering: Valuable concentrates like gold, copper, or zinc are processed using filter presses to extract water, ensuring transportable and saleable material.
