Bauxite bu nkume sedimentary nke juputara na alumina, isi ihe maka ime aluminom. It is generally easy to mine because it is found near the surface of the terrain. Otú ọ dị, the process of separating the alumina from the other base elements in bauxite can be environmentally unfriendly.
Maka bauxite nụchaa usoro Bayer — nke na-ekewa alumina bara uru na ihe ndị gbara ya gburugburu gụnyere ihe ndị caustic, okpomọkụ dị elu, na nrụgide. Ihe mkpofu na-akpata, karịsịa site na bauxite, bụ slurry a na-akpọkarị “uhie apịtị,”Nke a ghaghi idebe ya na ọdọ mmiri ruo mgbe a ga-eme ka nsị nke ngwọta ya kwụsị. Apịtị uhie nwere ike inwe mmetụta dị egwu gburugburu ebe obibi ma ọ bụrụ na ọdọ mmiri ndị ahụ ejide ya wee hapụ azịza ya n'ime ụzọ mmiri mpaghara.
Iji wedata mmepụta nke apịtị uhie ma wepụkwuo alumina na mbido usoro ahụ, ST Equipment & Technology nke tribo-electrostatic belt separator can be used prior to the Bayer process. It removes silicates from bauxite and increases available alumina from finely ground bauxite. Ihe si na ya pụta bụ mgbake nke ọnụ ọgụgụ dị ukwuu nke alumina, ala ojiji nke oké ọnụ caustic soda, 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 Equipment & Teknụzụ belt separator dịkwa oke ike ịrụ ọrụ nke ọma. It can process a large amount of feed material per hour. It is small enough to be used on-site at refining operations, mbenata ugwo ugwo.
Yabụ, ị ga-echekwa ego na nhazi, 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.
