Bauxite waa dhagax dhoobo ah oo hodan ku ah alumina, salka loo sameeyo aluminium. It is generally easy to mine because it is found near the surface of the terrain. Si kastaba ha ahaatee, the process of separating the alumina from the other base elements in bauxite can be environmentally unfriendly.
U bauxite turxaan bixinta nidaamka Bayer - taas oo kala saareysa alumina qaali ah iyo waxyaabaha ku hareeraysan waxay ku lug leedahay maaddooyin caustic ah, heerkulka sare, iyo cadaadis. Qashinka ka yimaada qulqulka, gaar ahaan ka bauxite, waa slurry guud ahaan loo yaqaan "dhoobo cas,”Taasi waa in lagu hayaa balliyada haynta ilaa suntan xalka loo dhexdhexaadinayo. Dhoobada cas waxay yeelan kartaa saamayn daran oo deegaanka ah haddii balliyada hayaa ay fashilmaan oo xalka lagu sii daayo marin biyoodka maxalliga ah.
Si loo yareeyo soo saarka dhoobada cas loona soo saaro alumina badan bilowga hawsha, ST Qalabka & technology ee kalasooca suunka tribo-electrostatic can be used prior to the Bayer process. It removes silicates from bauxite and increases available alumina from finely ground bauxite. Natiijadu waa soo kabashada qadar badan oo alumina ah, isticmaalka hoose ee soodhada qaaliga ah ee qaaliga ah, 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 Qalabka & Kala sooca suunka Teknolojiyada sidoo kale waa mid si aad ah u tamar badan. It can process a large amount of feed material per hour. It is small enough to be used on-site at refining operations, dhimista kharashka maraakiibta.
In si kale loo dhigo, lacag baad ku keydin doontaa hawshaada, 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.
