Chachikulu poyambira mfundo zotayidwa kuyenga ndi bauxite. Popeza aluminiyamu ndichinthu chogwira ntchito ndipo sizichitika mwachilengedwe, zotayidwa kulemera zofuna miyala kuyengedwa kuti zokolola aluminiyamu ndi zotayidwa, zomwe zimapangitsa kuti m'badwo wotsalira wazopangidwa ndi zinthu.
Kugwa kwakukulu kwambiri pakuwongolera kwa bauxite, njira ya Bayer, ndiye kulenga kwa zotsalira za alumina (ARR)- yodziwika ngati "matope ofiira" - chivundikiro chowopsa chomwe chimafunikira kukhalabe m'madziwe ndikuwunika kwa nthawi yayitali, pa mtengo wokwera. Izi zimayambitsa gawo la ngozi zowononga zachilengedwe komanso zaumoyo wa anthu ngati maiwewewa akulephera pazifukwa zilizonse ndipo matope ofiira akalowa m'madzi kapena m'malo okhala ndi anthu ambiri. Ngakhale atafufuza mosalekeza, palibe mulingo wofunika kwambiri wamadothi ofiira ogwiritsanso ntchito bwino.
cha ku Switzerland Zida & Technology LLC (STET) wapanga tribo-electrostatic lamba olekanitsa omwe ali oyenera kuti apindule ndi zabwino kwambiri (ochepera micron imodzi) kuti amtengo coarse (500 microns) tinthu tating'onoting'ono. Njira yayikulu yotsika mtengo ndiyothandiza ndipo imatha kuwonjezera alumina omwe amapezeka ku bauxite uku akumachepetsa mphamvu.
Njira ya STET ndi yamadzi komanso yopanda mankhwala yokha, zomwe zimapanga co-bauxite co-product chomwe chitha kugwiritsidwanso ntchito mopindulitsa pakupanga simenti, mosiyana matope ofiira. Njira ya STET imachotsa zinthu zina zoyipa zomwe zingakanidwe ndi njira ya Bayer ngati matope ofiira. Komabe, Njira ya STET imagwira ntchito pang'ono. Kuphatikiza apo, kutsitsimuka kwa bauxite kumapangitsa kuti ndalama zisungidwe mu Bayer, kuphatikizapo kuchepa kwa mankhwala a caustic koloko, kusowa kwa madzi abwino, kusunga mphamvu chifukwa cha kuchepa kwamphamvu kwa inert oxides, komanso kuchepetsa matope ofiira. Nthawi zina, masanjidwe a STET olekanitsa; wopanda madzi komanso wopanda mankhwala, otsika kalasi bauxite, ikhoza kugulitsidwanso kwa opanga simenti kuti igulitse ndalama zake.
Kuphatikiza apo, Tekinoloje ya STET ikhoza kupatsa opanga bauxite ndi oyenga alumina maubwino ena kuphatikiza kuphatikizapo kuchepetsedwa kwa mtengo wauuxite, Kukula kwa malo okhala otetemera ofiira, ndikukhala ndi moyo wopambanitsa wa migodi ya bauxite yomwe ilipo pakukonzanso magwiridwe antchito ndikukulitsa kuchira. Madzi- zopangidwa ndi zinthu zopanda mankhwala zopangidwa ndi STET zimathandizanso kupanga simenti yambiri popanda kulandira chithandizo chisanachitike.
Ngati muwonjezera zonse, Ndizochita “zambiri” zomwe mutha kugwiritsa ntchito zolimbitsa thupi zanu. Contact cha ku Switzerland Zida & Technology and let us help you gain more from your current operations while lowering your operating costs and increasing your environmental friendliness.
