In the mining field, our products are used for solid-liquid separation: all stones are extracted in form of blocks, cut in pieces and often polished. Water is the standard fluid used for these processes; the water recovery requires filter presses, belt presses, vacuum drum filters... equipped with proper ready-made cloths.
Testori has a wide range of products (generally polyamide, polypropylene and polyester) particularly resistant to the abrasion of the treated sludge. The stones and powders treated in mining industry are: coal, granites/marble, clay, gravel, kaolin, feldspar etc. Also extraction, concentration and purification of metal ores such as aluminium, zinc, lead, nickel, gold, silver, platinum, lithium, niobium, etc. request solid-liquid separation processes. Our products are equally effective in the electrolytic production process of non-ferrous metals (Zn, Pb, Cr, Cu, Cd, In, Al, Ga, As) and precious metals recovery where solid-gas separation is also involved.
Also melting processes to produce ferro-alloys request dedusting plant and
our filter bags.
Testori filter media have excellent retention efficiency, high tensile strength, low permeability and good cake release withstand the different process parameters: Ph, temperature, particles morphology and nature of minerals (often hard and abrasive).
