Ukucutshungulwa Kwezimbiwa wukuhlukaniswa kwamaminerali ahlosiwe kwamanye amaminerali azungezile. Le nqubo ihlukaniswe izingxenye ezimbili. Kuye nge-mineral, ukucubungula kungenziwa ngezindlela ezihlukahlukene. Ngezinye ST Izinsiza kusebenza & ubuchwepheshe (STET), sizinikele ekutholeni imvelo enobungani, eshibhile, kanye nesixazululo esisheshayo sokucutshungulwa kwezimbiwa okujwayelekile. Yingakho sidale STET yethu isihlukanisi se-triboelectric. Ngalesi sixhobo sokuhlukanisa amaminerali, thola umkhiqizo wekhwalithi ephezulu ngesikhathi esincane, ngenani eliphansi.
Ukucubungula amaminerali kuyinqubo yokukhipha amaminerali emhlabathini. Ukuzihlukanisa zibe izingxenye eziwusizo nezingezona usizo. Ngokwesibonelo, uma uzama ukukhipha insimbi emhlabathini, uzokhipha inamba yamanye amaminerali ngayo. Ukuze uhlukanise lawa amanye amaminerali ensimbi ozama ukuyikhipha, idiphozi izodinga ukuthi idlule ekucutshungulweni kwezimbiwa. Le nqubo ihlukaniswe ngezinyathelo ezimbili eziyinhloko—ukulungiselela nokuhlukanisa.
Kunezinyathelo ezimbili ezibalulekile ekusetshenzisweni kwezimbiwa. Isinyathelo ngasinye singenziwa ngezindlela eziningi. Imishini ethile yokuhlukanisa amaminerali kanye namasu akhethiwe ngokusekelwe kumaminerali ofuna ukuwakhipha kanye nokwakheka kwawo kwamakhemikhali.
Ukuze uhlukanise kahle amaminerali akhethiwe ku-ore, kumele ilungiswe. Inhloso yokulungisa itshe lensimbi ukwenza ukuhlukana kube lula kumaminerali ahlukene. Iminerali ngayinye kufanele ivezwe kancane noma ngokugcwele ukuze inqubo yokuhlukanisa isebenze. Ukuveza amaminerali, the ore deposits must be crushed or ground into small pieces.
Izingcezu ezinkulu ze-ore zifakwa ku-crusher noma i-grinder bese ziguqulwa zibe izingcezu ezincane. Lezi zingcezu zibe sezibuyiselwa ku-crusher noma i-grinder kuze kube yilapho usayizi othize oyidingayo ukuze uhlukanise ufinyelelwe. Ama-crusher amaningi nama-grinders angasetshenziswa ukufeza lo sayizi ofanele. Imishini yokucubungula amaminerali ngoba lokhu kuhlanganisa imihlathi kanye gyratory crushers, ama-cone crushers, ama-crushers anomthelela, ama-crushers, and grinding mills.
Ukuhlukaniswa kwamaminerali yilapho amaminerali awusizo ehlukaniswa namaminerali angenamsebenzi (eyaziwa nangokuthi i-ganggue material). Kuye ngohlobo lweminerali ofuna ukuyikhipha, ungasebenzisa amasu okuhlukanisa ahlukene, noma inhlanganisela yamasu, including wet separation or dry separation.
Ukuhlukaniswa okumanzi kufaka phakathi ukusetshenziswa kwamanzi ukuze kuhlukaniswe amaminerali. Izinhlobo eziyinhloko zokuhlukaniswa okumanzi ukuhlukaniswa kwe-flotation kanye nokuhlukaniswa okumanzi kazibuthe. Ukuhlukaniswa kwe-flotation kusebenzisa ukwakheka kwamakhemikhali eminerali oyifunayo. Ngokukhetha i-reagent yamakhemikhali ethize esabelana namaminerali, i-mineral ibambelela ekuphenduleni-ukuyihlukanisa nezinye izinto. Ngokuhlukana kukazibuthe okumanzi, i-mineral iqondiswe ngokusekelwe kubuningi bayo kazibuthe. Esigubhini esinamanzi, amandla kazibuthe aphansi noma aphezulu asetshenziswa ukuhlukanisa amaminerali. Ngokuhlukana okumanzi, umkhiqizo wokugcina kumele womiswe ngokukhipha amanzi.
Ukwehlukanisa okomile akusebenzisi amanzi futhi kuhambisana nemvelo. Izinhlobo eziyinhloko zokuhlukanisa okomile ukuhlukaniswa kwamandla adonsela phansi, ukuhlukana kwamagnetic okomile, kanye nokuhlukaniswa kwe-electrostatic. Ukwehlukaniswa kwamandla adonsela phansi kusebenzisa amandla adonsela phansi ahlukahlukene kumaminerali ukuze kuqondiswe kumaminerali akhethwayo. Ukwehlukanisa kazibuthe okomile kusebenzisa inqubo efanayo nokuhlukanisa kazibuthe okumanzi kodwa ngaphandle kokusebenzisa amanzi. Ukuhlukaniswa kwe-electrostatic kusebenzisa inkokhiso yamaminerali ukuze kuyihlukanise kwamanye.
Ukuhlukaniswa kwe-Triboelectric kungenye yezindlela ezingcono kakhulu zokuhlukanisa amaminerali komunye nomunye. Ngaphakathi kwesihlukanisi se-triboelectric, izinhlayiya zikhokhiswa, ihlukaniswe ngokukhokhiswa, futhi ihlukaniswe amandla adonsela phansi. Konke lokhu kwenziwa ngomshini owodwa. Amaminerali ahlukaniswa ngokushesha futhi kulula. Umphumela uba umkhiqizo owomile ngokuphelele olungele i-pelletization. Ngaphezu kwalokho, ukuhlukaniswa kwe-triboelectric kuvumela izindleko eziphansi zokutshalwa kwezimali / zokusebenza futhi kubangela umthelela omncane emvelweni.
Ifuna okusheshayo, indlela elula yokucubungula amaminerali? Sebenzisa imishini yokuhlukanisa i-electrostatic ye-STET. Sihlinzeka ngemishini yesimanje yokuhlukanisa amaminerali kumakhasimende ethu futhi siwasize. Ufuna ukufunda okwengeziwe? Xhumana nathi namuhla!
