Bauxite is 'n sedimentêre rots wat ryk is aan alumina, die basis vir die maak van aluminium. It is generally easy to mine because it is found near the surface of the terrain. Maar, the process of separating the alumina from the other base elements in bauxite can be environmentally unfriendly.
Vir bauxite verfyning van die Bayer proses-wat skei die waardevolle alumina van die omliggende materiaal behels oorsaaklike materiaal, hoë temperature, en druk. Die gevolglike afvalstroom, veral van bauxite, is 'n flodder algemeen bekend as "rooi modder," wat gehou moet word in die hou van damme totdat die toksisiteit van die oplossing is neutraliseer. Rooi modder kan 'n ernstige omgewingsimpak hê as hou damme misluk en die oplossing is vrygestel in plaaslike waterweë.
Om die produksie van rooi modder te verminder en onttrek meer alumina aan die begin van die proses, ST Toerusting & Tegnologie se tribo-elektrostatiese gordel skeider can be used prior to the Bayer process. It removes silicates from bauxite and increases available alumina from finely ground bauxite. Die resultaat is die herstel van 'n groter bedrag van alumina, laer gebruik van duur oorsaaklike koeldrank, and a reduced need for red mud-holding ponds. A reduction in the amount of energy needed during the Bayer process to heat and pressurize the mined materials.
ST Toerusting & Tegnologie se gordel skeiding is ook uiters energie-doeltreffende. It can process a large amount of feed material per hour. It is small enough to be used on-site at refining operations, vermindering van gestuur koste.
Met ander woorde, jy sal geld spaar op verwerking, making more money on the additional alumina. You’ll be pulling from the feed material, and you can present your mining company as an eco-friendly operation. It goes a long way toward building a good reputation with the locals.
