In the mining dewatering treatment sector, the filter press is used for the tailing and the concentrate. Coal mines have to deal with the problem of disposing of the uneconomic material, by-product of the coal production. Especially, Matec machines can dewater the waste fines suspended in water, recovering them, cleaning water and eliminating tailing ponds.
In the mining industry, wastewater treatment is essential to managing tailings and concentrating valuable materials. Matec’s filter presses are key in this process, particularly for coal mining where uneconomic by-products and waste fines are prevalent. Using advanced dewatering technology, Matec systems separate waste solids from water, effectively reducing tailing ponds and recovering usable water, supporting environmental compliance and operational efficiency.
Matec filter presses are specifically designed to achieve low residual moisture levels in concentrate recovery, with cakes as low as 6-7% moisture. For this, membrane plates and the core blow accessory are used, enhancing water extraction and ensuring a drier cake output. This is especially useful for high-value concentrates where residual moisture reduction is critical to maximizing the resource value.
Mining wastewater can contain heavy metals and other contaminants such as arsenic, lead, cadmium, chromium, iron, manganese, aluminum, and nickel. Proper filtration of wastewater not only clarifies it but also allows for the recovery of valuable materials that would otherwise be lost, turning waste into potential revenue streams.
The coal industry, a significant contributor to global energy, heavily relies on Matec’s filtration systems. The U.S., one of the top coal producers, has over 50 Matec filtration plants installed across major mining sites. The iron-ore industry also benefits, focusing on the extraction of metals like iron, nickel, and noble metals (gold, silver, platinum). With rising market values, recovering mineral concentrates efficiently is crucial for profitability.
Wastewater treatment is essential in mining to manage tailings, recover valuable materials, and ensure compliance with environmental regulations. It helps reduce the use of tailing ponds and recycles water for reuse.
Matec filter presses dewater mining waste by separating solids from water, producing a dry, compact cake. With advanced technology, they reduce residual moisture in the concentrate, enhancing resource recovery.
Mining wastewater often contains heavy metals and contaminants such as arsenic, lead, cadmium, chromium, iron, manganese, aluminum, and nickel, which need to be filtered out to protect the environment.
Industries such as coal and iron-ore mining greatly benefit. Matec’s filter presses improve water management, reduce waste, and recover valuable minerals, making operations more sustainable and profitable.
