Bauxite ke lefika la sedimentary le ruileng ka alumina, motheo oa ho etsa aluminium. It is generally easy to mine because it is found near the surface of the terrain. Leha ho le joalo, the process of separating the alumina from the other base elements in bauxite can be environmentally unfriendly.
Bakeng sa ho hloekisa bauxite ts'ebetso ea Bayer-e arolang alumina ea bohlokoa ho thepa e e potileng e kenyelletsa lisebelisoa tsa caustic, mocheso o phahameng, le khatello. Molapo o hlahisoang ke litšila, haholo-holo ho tsoa ho bauxite, ke seretse se tsejoang ka hore ke “seretse se sefubelu,”E tlamehang ho bolokoa ka matamong ho fihlela chefo ea tharollo e fokotsoa. Seretse se sefubelu se ka ba le tšusumetso e matla tikolohong haeba ho tšoara matangoana ho hloleha 'me tharollo e ntšetsoa metsing a lehae.
Ho fokotsa tlhahiso ea seretse se sefubelu le ho ntša alumina e ngata qalong ea ts'ebetso, ST Helmets & Technology ea tribo-electrostatic lebanta kgaoganyo can be used prior to the Bayer process. It removes silicates from bauxite and increases available alumina from finely ground bauxite. Phello ke ho hlaphoheloa ha palo e kholo ea alumina, tšebeliso e tlase ea soda e theko e phahameng, 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 Helmets & Sekhaohanyi sa lebanta sa Technology le sona se boloka matla a maholo. It can process a large amount of feed material per hour. It is small enough to be used on-site at refining operations, fokotsa litšenyehelo tsa thomello.
Ka mantsoe a mang, o tla be o boloka chelete ha o sebetsoa, 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.
