I-Bauxite yidwala le-sedimentary elicebile nge-alumina, isisekelo sokwenza i-aluminium. It is generally easy to mine because it is found near the surface of the terrain. Nokho, the process of separating the alumina from the other base elements in bauxite can be environmentally unfriendly.
Okwe-bauxite ukucwenga inqubo yeBayer-ehlukanisa i-alumina eyigugu ezintweni ezizungezile kubandakanya izinto eziyimbangela, amazinga okushisa aphezulu, nengcindezi. Ukusakazeka kwemfucuza okuvelayo, ikakhulukazi kusuka ku-bauxite, udaka olwaziwa ngokuthi “udaka olubomvu,”Okumele kugcinwe kubanjwe amachibi kuze kube yilapho ubuthi besisombululo bungasasebenzi. Udaka olubomvu lungaba nomthelela omkhulu kwezemvelo uma ukubamba amachibi kungaphumeleli futhi isixazululo sikhishwe emifuleni yamanzi yasendaweni.
Ukunciphisa ukukhiqizwa kodaka olubomvu futhi kukhishwe i-alumina eyengeziwe ekuqaleni kwenqubo, ST Izinsiza kusebenza & technology isihlukanisi sebhande le-tribo-electrostatic can be used prior to the Bayer process. It removes silicates from bauxite and increases available alumina from finely ground bauxite. Umphumela ukutholakala kwesamba esikhulu se-alumina, ukusetshenziswa okuphansi kwesoda ebizayo ye-caustic, 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 Izinsiza kusebenza & Isihlukanisi sebhande lobuchwepheshe futhi songa amandla ngokweqile. It can process a large amount of feed material per hour. It is small enough to be used on-site at refining operations, ukunciphisa izindleko zokuthumela.
Ngamanye amazwi, uzobe wonga imali ngokucubungula, 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.
