Kunezinhlobo eziningi ezahlukene i-iron ore beneficiation technology etholakalayo. Ngayinye inobuhle bayo kanye nebubi bayo futhi ngayinye isebenzisa indlela ehlukile ukuze kuzuzwe umphumela ofanayo. Lesi sihloko, ST Izinsiza kusebenza & ubuchwepheshe (STET), izokuhambisa ngezici zobuchwepheshe obuhlukene bokuzuza kwensimbi.
Kunezinyathelo ezintathu eziyinhloko zokukhiqizwa kwensimbi yensimbi—ukumba, ukucutshungulwa, kanye ne-pelletizing. Mining is the process of taking nsimbi emhlabeni; ukucubungula kususa zonke izinto ezingenamsebenzi (igenge). Ukuzuza ibanga elithile lokwakheka kwamakhemikhali kanye ne-pelletizing ukuguqula izinto ezicutshunguliwe zibe zincane, iyunithi esebenzisekayo. Ukucubungula i-iron ore kuyisinyathelo esibaluleke kakhulu ekukhiqizeni ama-pellets kanye namasu amaningi ahlukene asetshenzisiwe futhi athuthukiswa.
Uma amadiphozithi ensimbi ekhishwa emhlabathini, kumele zicutshungulwe ukuze kwandiswe insimbi futhi kwehle ukugcwala kwamaminerali e-ganggue. Idiphozi ngayinye inezindawo zayo zamakhemikhali eziyingqayizivele. Ukuze udale inani elisebenzisekayo lensimbi (Fe), amanye amaminerali kufanele akhishwe ensimbi. Amanye amaminerali angangcolisa insimbi i-silica- kanye namaminerali athwala i-alumina njenge-quartz, kaolinite, gibbsite, i-diaspore, kanye ne-corundum.
Imishini yobuchwepheshe bokuhlukanisa ivumela insimbi yensimbi esezingeni eliphansi ukuthi icutshungulwe ibe insimbi yezinga eliphezulu kakhulu. Izinhlobo ezahlukene zemishini yobuchwepheshe bokuhlukanisa zingena ezigabeni ezimbili eziyinhloko—ukuhlukaniswa kwensimbi emanzi neyomile.
Ngaphakathi emanzi ukuzuza kwe-iron ore ubuchwepheshe, kukhona amasu ambalwa ahlukene. Lokhu kuhlanganisa ukuntanta kanye nokuqina okuhlukile kokuhlukaniswa kazibuthe okumanzi.
flotation ivame ukusetshenziswa kanye nokuhlukaniswa kazibuthe. Le nqubo isebenzisa i-reagent yamakhemikhali eyenza insimbi ibambelele ekuphenduleni futhi iyihlukanise nezinye izinto. Ngaphezu kokusetshenziswa kwamakhemikhali, amanzi ayadingeka ukuze kuqinisekiswe ukuthi ukusabela kusebenza kahle. Ngenxa yalokho, amanzi angcolile amaningi adalwa futhi ukwelashwa kwamanzi kuyadingeka. Ngokufanayo, ukuze kuqinisekiswe ukuthi ezinye zezinhlayiya ezinhle zihlukene nensimbi, desliming kuyadingeka. Nokho, i-desliming ingaholela ekulahlekelweni kwezinhlayiya zensimbi.
Ukuhlukana Kwezibuthe Ezimanzi (Amandla Aphansi kanye Nokuqina Okuphezulu) Ngesu lokuhlukanisa kazibuthe elimanzi amadiphozi ensimbi afakwa esigubhuni esishajwa ngozibuthe bese amanzi aphontshelwa kuso ukusiza ukuhlukanisa izinto.. Kuye ngokwakhiwa kwezinto esigubhu amandla kazibuthe aphansi noma aphezulu angasetshenziswa ukuhlukanisa izinhlayiya.. Nalapha, amanzi angcolile ayadalwa futhi ukwelashwa kwamanzi kuyadingeka.
Ngaphakathi ukuhlukaniswa kwensimbi eyomile, kukhona a amasu ambalwa engasetshenziswa. Zihlanganisa ukuhlukaniswa kwamandla adonsela phansi, ukuhlukana kwamagnetic okomile, kanye STET dry electrostatic ngokwahlukana.
Ukuhlukaniswa kwamandla adonsela phansi kuncike kakhulu ekutheni ingxenye yenqubo ihambe kahle kangakanani. Ngale nqubo, amandla adonsela phansi asetshenziswa njengamandla amakhulu okuhlukanisa insimbi kumaminerali e-ganggue. I-ayoni inokudonsa okuphezulu kwamandla adonsela phansi kunamanye amaminerali etholakala nawo, kanjalo namandla adonsela phansi, izodonswa phansi ngokushesha kunamanye amaminerali. Kunemishini eminingi ehlukene esebenzisa amandla adonsela phansi njengendlela eyinhloko yokuhlukanisa.
Ukwehlukana Okumile Magnetic empeleni iyafana nokuhlukaniswa kazibuthe okumanzi ngaphandle kokuthi ayisebenzisi amanzi ukusiza ukwenza lula inqubo yokuhlukanisa.. Kunalokho, incike kuphela ezintweni kazibuthe zamaminerali ukuze ziwahlukanise komunye nomunye. Ukwehlukanisa kazibuthe okomile akusebenzi kahle ezinhlayiyeni ezinhle.
STET Dry Electrostatic Separation iyimishini yobuchwepheshe yokuhlukanisa insimbi eyomile engcono kakhulu etholakala kalula, uma kungenjalo amatshe ensimbi angatholakali. Le nqubo isebenzisa ukushaja okungekuhle kanye nokuhle kwensimbi ukuyihlukanisa kwamanye amaminerali.
Kuningi izinzuzo ukusebenzisa STET dry electrostatic ngokwehlukana. Ngokungafani nezinye izindlela zokuhlukanisa insimbi eyomile, ukuhlukaniswa kwe-electrostatic kuvumela ukutholwa kwezinhlawulo zensimbi ebingalahleka ngenye indlela kumasekethe okucubungula ajwayelekile. Ngaphezu kwalokho, ivumela izindleko eziphansi zokutshala imali/zokusebenza futhi ibangele umthelela omncane endaweni ezungezile (okuvumela ukuvunyelwa kalula). Ngokufanayo, ukuhlukaniswa kwe-electrostatic kuvimbela isidingo sokusetshenziswa kwamanzi, ukusetshenziswa kwamakhemikhali, futhi iqeda ukugcinwa/ukulahlwa kwemisila emanzi.
Ingabe ufuna enye indlela yokuzuza ngensimbi engenawo amanzi? STET dry electrostatic separation yisixazululo sakho. ST Izinsiza kusebenza & ubuchwepheshe (STET) ihlinzeka ngokuhlukaniswa kwensimbi enhle kumakhasimende kuwo wonke umhlaba. Ithimba lethu lochwepheshe lizinikele ekusizeni wena. Xhumana nathi namuhla ukuze ubone ukuthi ibhizinisi lakho lingazuza kanjani kulwazi lwethu nobungcweti.
