Il-Bauxite huwa blat sedimentarju li huwa għani fl-alumina, il-bażi biex isir l-aluminju. It is generally easy to mine because it is found near the surface of the terrain. Madankollu, the process of separating the alumina from the other base elements in bauxite can be environmentally unfriendly.
Għar-raffinar tal-bauxite tal-proċess ta' Bayer—li jissepara l-alumina siewja mill-materjali tal-madwar tinvolvi materjali kawstiċi, temperaturi għoljin, u l-pressjoni. Il-fluss tal-iskart li jirriżulta, speċjalment mill-bauxite, huwa demel likwidu ġeneralment magħruf bħala "tajn aħmar," li għandhom jinżammu fl-azjenda għadajjar sakemm it-tossiċità tas-soluzzjoni tiġi newtralizzata. It-tajn aħmar jista' jkollu impatt ambjentali sever jekk l-għadajjar li jżommu ma jirnexxix u s-soluzzjoni tiġi rilaxxata fil-passaġġi fuq l-ilma lokali.
Biex tiġi minimizzata l-produzzjoni tat-tajn aħmar u tiġi estratta aktar alumina fil-bidu tal-proċess, ST Tagħmir & teknoloġija tal 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. Ir-riżultat huwa l-irkupru ta' ammont akbar ta' alumina, użu aktar baxx ta' soda kawstika għalja, 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 Tagħmir & Is-separatur taċ-ċinturin tat-teknoloġija huwa wkoll estremament effiċjenti fl-użu tal-enerġija. It can process a large amount of feed material per hour. It is small enough to be used on-site at refining operations, it-tnaqqis tal-ispejjeż tat-tbaħħir.
Fi kliem ieħor, int ser tkun qed tiffranka l-flus fuq l-ipproċessar, 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.
