Ziningi izindlela amaminerali angacutshungulwa ngazo. Enye yalezi zindlela ngenqubo yokuhlukaniswa kwe-electrostatic. Le nqubo ivumela ama-mineral processors ukuthi ahlukanise amaminerali asezingeni eliphezulu futhi awahlukanise kwamanye amaminerali e-ganggue. Ngakho-ke kuyini ukuhlukaniswa kwe-electrostatic futhi kusebenza kanjani? Kulesi sihloko, ST Izinsiza kusebenza & ubuchwepheshe LLC (STET), explains the key features of electrostatic separation and how we incorporate it into our imishini yobuchwepheshe bokuhlukanisa.
Ukuhlukaniswa kwe-electrostatic kuhlukanisa amaminerali ngokusekelwe ezintweni zawo ezinegethivu noma ezinhle. Ukuhlukaniswa kwe-electrostatic kusetshenziswa ngezindlela eziningi, kodwa isetshenziswa kakhulu embonini yokucubungula izimbiwa. Isinyathelo esibalulekile ekucutshungulweni kwezimbiwa sihlukanisa amaminerali abalulekile ezingxenyeni ezingabalulekile (igenge). This step allows for the production of the high-quality minerals needed in the creation of different products.
Kunezindlela ezimbalwa ezahlukene lokho imishini yokuhlukanisa amaminerali isebenzisa ukuhlukaniswa kwe-electrostatic. Esimeni ngasinye, inhloso yomshini ukuhlukanisa izinhlayiya ezishajwa ngokuhlukile kwenye. Lokhu kuqedwa ngepuleti elihambisanayo, ipuleti angular, noma isihlukanisi sezigubhu. Kulelo nalelo, kunezici ezintathu eziyinhloko—ukushajwa kwezinhlayiya, ukudluliswa kwalezi zinhlayiya, kanye nokuhlukaniswa kwezinhlayiya. Each of these steps is necessary to produce a high-quality product.
Phakathi nesigaba sokushaja izinhlayiyana, amaminerali athola amashaji kagesi aphambene. Esigabeni sokudlulisa, lezi zinhlayiya ezishajiwe zikhangwa ipuleti elinenani eliphikisayo (amapuleti amahle aheha izinhlayiya ezingezinhle futhi ngokuphambene nalokho) futhi idluliselwe ezindaweni ezahlukene. Futhi ekugcineni, esigabeni sokuhlukana, they are separated into two distinct compartments based on the electric charges.
Ngoba kunezinhlobo ezahlukene zemishini yokuhlukanisa amaminerali e-electrostatic, ngamunye usebenzisa izindlela eziyingqayizivele zokuhlukanisa indaba. Ukuze lesi sihloko, sizodlula ngasinye salezi zigaba sisebenzisa isibonelo se-triboelectric Isihlukanisi se-STET.
Esinye sezici ezibalulekile zokuhlukaniswa kwe-electrostatic ukushajwa kwezinhlayiya. Ukuze kuhlukaniswe izinhlayiya, kumele baqale bashajwe ngogesi. Izinhlayiya zokushaja zingenzeka ngezindlela eziningi, kodwa isihlukanisi STET isebenzisa ukushaja i-triboelectric. Ukuze wenze lokhu, amaminerali afakwa kusihlukanisi futhi awele esikhaleni se-electrode (isikhala phakathi kwepuleti eline-positively charged kanye ne-negative charge). Lesi sikhala yilapho izinhlayiya zishayisana futhi zishajwe. Some particles will become negatively charged and others will become positively charged.
Ngemva kokuba izinhlayiya zikhokhisiwe, bese behlukana. Ngoba lezi zinhlayiya zinegethivu noma kahle, zidonselwa emapuletini ashaywe ngokuphambene. Izinhlayiya ezinhle zikhangwa ipuleti elibi. Ngokufanayo, izinhlayiya ezimbi zikhangwa ipuleti elihle. Between the plates and the particles is an open-mesh belt that conveys the particles in opposite directions. Izinhlayiya ezifakwe kahle zikhangwa phezulu futhi zihanjiswa yibhande kwesokudla. Ngokungqubuzanayo, the negatively charged particles are attracted to the bottom and moved by the belt to the left.
Ngokusebenzisa izinqubo ezintathu ezibalulekile zokuhlukaniswa kwe-triboelectric, ama-mineral processors angakhiqiza amaminerali asezingeni eliphezulu angasetshenziswa ekwakhiweni kwemikhiqizo ehlukahlukene. ST Izinsiza kusebenza & ubuchwepheshe LLC (STET) Manje njengoba usubonile ukuthi isihlukanisi se-triboelectric singanciphisa kanjani ukungcola okubangelwa umlotha wamalahle, MA.
