Amatshe amaningi aqukethe uhlobo oluthile lwezinsimbi noma amaminerali. Akubona bonke abanokugxila okubalulekile ngokwanele ukuze bathethelele ukumba izimayini. Lezo eziqukethe izinto ezibalulekile kwezentengiso yilezo ezikhethelwa ukucutshungulwa kwezimbiwa.
Ukucutshungulwa kwamaminerali kuhamba ngamagama amaningi. Kwesinye isikhathi kubizwa ngokuthi yi-beneficiation, ukugqoka amaminerali, ukugqoka insimbi, ukukhishwa kwamaminerali, ukuzuzisa amaminerali, noma ubunjiniyela bamaminerali. Wonke la magama angasetshenziswa ngokushintshana kodwa abhekisela ohlelweni lokuhlukanisa amaminerali asebenzisekayo namaminerali anenani eliphansi ensimbi eyaziwa ngokuthi i-ganggue..
samaminerali iwela ezigabeni ezimbili, imanzi futhi yomile. Ukuhlomula okumanzi, noma ukugaya okumanzi, ngokusekelwe ku-mineral density, ihlanganisa ne-froth flotation ukunciphisa usayizi wezinhlayiyana futhi ihlukanise amaminerali. Ngamanye amazwi, amaminerali afakwe kwisisombululo esiwahlukanisa ngokusekelwe ekuncibilikeni kwawo kwamanzi. Inzuzo eyomile isekelwe kusethi ehlukile yezakhiwo ezibonakalayo ezihlanganisa ubukhulu bamaminerali, isimo, ukuminyana, noma ukuthambekela kazibuthe. Ubuchwepheshe bokuhlukanisa okomile busebenzisa amanzi amancane uma kukhona amanzi ngesikhathi sokucubungula futhi kuyinkambu ekhulayo ngenxa yayo izinzuzo ekwehliseni i-carbon footprint yethu.
Njengoba kungekho usayizi owodwa olingana nayo yonke indlela yokuhlukanisa amaminerali, kunezinhlobonhlobo eziningi zobuchwepheshe bokuhlukanisa amaminerali. Imboni yemishini yobuchwepheshe bokuhlukanisa iyaqhubeka nokuthuthukisa amasu okuhlukanisa amaminerali. I-Steqtech, inkampani yokuhlukanisa amaminerali e-Needham, MA, ungumholi kulo mkhakha. Sakhe a triboelectrostatic ibhande isihlukanisi usebenzisa indlela eyomile yokuzuza esebenza kahle futhi eco-friendly.
Isinyathelo sokuqala siwukubona umehluko phakathi kwensimbi ukuze lezo zimfanelo zisetshenziswe ukuhlukanisa amaminerali emadwaleni aqukethe.. Lokhu kufezwa ngokuchotshozwa kanye/noma ukugaya (ukuqaliswa) kuze kube yilapho amaminerali evezwa ngokugcwele, noma “khululiwe.”
Ekucutshungulweni kwamaminerali, commition isebenzisa amandla amaningi, nakuba ekuqaleni bekuwumsebenzi onzima kakhulu. Emakhulwini eminyaka adlule, ama-pestles amancane asebenza ngesandla kanye nodaka asetshenziselwa ukuchotshozwa, namatshe okugaya, eziqhutshwa amadoda, amahhashi, noma amandla amanzi asetshenziselwa ukugaya. Namuhla ama-crushers nemishini yokugaya ayisheshise kakhulu le nqubo.
Ngenxa yomehluko omningi phakathi kwamaminerali, bangaphendula ngendlela ehlukile ku-commition. Ngokwesibonelo, imineral eyodwa ingase ibe thambile noma ibe nezinhlamvu ezinkulu noma ezincane kunenye, okubangela ukuthi ihlukane kalula.
Ukuchoboza nokugaya kuvame ukusebenza ngokuhambisana nokulinganisa, okuhlanganisa amaminerali ngokosayizi. Indlela elula yokulinganisa iwukuhlola, edlula izinhlayiya esikrinini.
Ukukhipha amanzi ngesinye isigaba esibalulekile sokucubungula amaminerali esisusa noma yimaphi amanzi amuncwa izinhlayiya zamaminerali. Izinqubo zokukhipha amanzi zihlanganisa izikrini, ukuhlunga, nokomisa okushisayo. Ngemva kokukhipha, amanzi ayahlanzwa, bese ijikeleziswa kabusha ukuze isetshenziswe emisebenzini yezitshalo.
Izakhiwo ezahlukene zamaminerali ziyisisekelo sokuhlukaniswa okuphumelelayo, okugxilisa izinhlayiya ezibalulekile. Ukucubungula futhi kuyawahlukanisa ne-ganggue, ebese ilahlwa. Izakhiwo zokuhlukanisa zihlanganisa i-physicochemical (ukuhlukaniswa kwe-flotation), ukuminyana (ukuhlukaniswa kwamandla adonsela phansi), kanye kazibuthe noma ugesi (ukuhlukana kazibuthe kanye electrostatic).
Ubuchwepheshe bokuhlukanisa i-Electrostatic (esetshenziswa kwa-ST Equipment & ubuchwepheshe) kuhlanganisa triboelectric ngokwahlukana, okuthi ngaphezu kokuba ngcono kwezemvelo, ingakwazi futhi ukubona izihlabathi zamaminerali ezicolekile kunezinye izindlela. ST Izinsiza kusebenza & Ibhande lokuhlukanisa i-triboelectric lobuchwepheshe lihlukanisa amaminerali ngokuya ngokuthi izinhlayiya zisabela kanjani lapho zibekwe endaweni ye-electromagnetic..
Ivunywe ngowe 1989, ST Izinsiza kusebenza & ubuchwepheshe LLC (STET) ibamba iqhaza elikhulu embonini yokuhlukanisa izimbiwa e-Needham, MA. Sithuthukisa futhi sithengise amaminerali omile ukucubungula imishini esetshenziselwa ukuzuzisa izinto eziyizinhlayiyana ezinhle. Lokhu kubandakanya ubunikazi, icwecwe triboelectrostatic ibhande isihlukanisi lokho kulula ukukuvumela futhi kungazuzisa izinto ngaphakathi kwezimboni ezimbalwa.
Izinhlayiya ezinosayizi omncane zizuzwa ngenqubo eyomile ngokuphelele, ngaphandle kwempahla eyengeziwe noma isikhathi sokumisa. Singathanda ukwabelana okwengeziwe ngalokho esikunikezayo, ngakho ngiyacela ukuthintana thina!
