Ukucubungula amaminerali kuhlukanisa amaminerali abalulekile kwi-ore ngokusebenzisa ukuzuza, okungukuphathwa kwempahla eluhlaza (njenge-iron ore) ukuthuthukisa izakhiwo zayo zomzimba noma zamakhemikhali. Kunezindlela eziningi ezahlukahlukene zale nqubo. Izindlela ezivame kakhulu ezimanzi nezomile, konke ukusetshenziswa imishini yobuchwepheshe bokuhlukanisa.
Enye yentuthuko ethembisayo ekucutshungweni okwomile ukwahlukaniswa kwe-triboelectric. Lobu buchwepheshe bunobubanzi obubanzi besayizi wezinhlayiyana obujwayelekile kunobuchwepheshe obujwayelekile bokuhlukaniswa kwe-electrostatic, okwenza ukuthi inzuzo ikwazi ukwenzeka ezimeni lapho i-flotation (indlela emanzi) yayiphumelele esikhathini esedlule.
ST Izinsiza kusebenza & ubuchwepheshe, LLC (STET) isungule i- Tribo electrostatic ibhande isihlukanisi lokho kunikeze imboni yokucubungula izimbiwa indlela yokuhlomula ngezinto ezinhle ngobuchwepheshe obomile ngokuphelele. Kunezinzuzo eziningi kule nqubo, kodwa ake siqale ngamagama athile.
Uyini Umehluko Phakathi Kokuhlomula Okumanzi nokomile?
Ukugaya okumanzi, ngokuhlangana ne-froth flotation, iyindlela esetshenziswa kakhulu ukunciphisa usayizi wezinhlayiyana nokukhulula amaminerali ore. Amaminerali afakwe kwisisombululo, okwenza ukuthi okokusebenza kwehlukane ngokuya ngokuthi ayaphindisela amanzi yini (i-hydrophobic) noma ukuheha amanzi (i-hydrophilic).
Ngenxa yenani lamanzi adingekayo, kanye nokufakwa kwamakhemikhali, i-froth flotation ayihambisani nemvelo. Ngaphezu kwalokho, akunakwenzeka ukuphinda usebenzise wonke amanzi asetshenzisiwe, ngoba izingxenye zenqubo amanzi kungenzeka ukuthi aqukethe amanani wokulandelela wama-reagents amakhemikhali.
Ukuzuza okomile kwehlukanisa udaba lwamaminerali ngokuya ngomehluko kuzakhiwo zalo ezifana nosayizi, isimo, ukuminyana, ukubenyezela, nokuthambekela kukazibuthe. Njengoba igama lisho, isebenzisa okuncane, uma kukhona amanzi lapho eqhutshwa, ukuqeda izingqinamba eziningi zokugaya okumanzi.
Yini isihlukanisi se-Electrostatic?
Ukuhlukaniswa kwe-electrostatic inqubo eyomile yokucubungula ehlukanisa amaminerali ngokuya ngokusebenza kwawo kagesi noma izakhiwo zokushaja kagesi. Isebenzisa amandla amancane kunokuhlukaniswa okuvamile okumanzi, futhi kuqeda kokubili isidingo sokomisa izindaba ezihlomulile kanye nokulahlwa.
Kuyini iTriboelectricity?
I-Triboelectricity yisayensi eneminyaka engamakhulu eminyaka ihlehlela emuva ekuhlolweni okwenziwe yisazi sefilosofi sasendulo esingumGreki uThales waseMileto. Uthole ukuthi ukugcoba inhlaka ngoboya kuholele ekushajweni kwe-electrostatic. Ngenxa yalokho, i-triboelectric ngesiGreki isho ukuthi “ugesi obangelwa ukugcotshwa.”
Asebenza kanjani ama-Triboelectric Charges?
Njalo inani likagesi lihle noma limbi. Into enenkokhiso evumayo isunduzela kude ezinye izinto ezikhokhiswe kahle, ebahlukanisa ngamaqembu ahlukene. Ngakolunye uhlangothi, inkokhelo evumayo ihlale iheha inkokhiso engeyona, okwenza ukuthi bobabili bahlangane. Iningi lansuku zonke static ugesi kuyinto triboelectric.
Umthelela triboelectric (noma ukushaja kathathu kagesi) uhlobo lokufakwa kukagesi kokuxhumana lapho izinto ezithile zikhokhiswa ngemuva kokuhlukaniswa nento ehlukile abaxhumane nazo. Kalula nje, ukuxubha izinto ezimbili ndawonye kudala ukungqubuzana phakathi kwendawo yazo futhi kudala ugesi.
Ngokwesibonelo, uma uhlikihla ipulaki lepeni lepulasitiki emikhonweni yakho, izofakwa ugesi futhi ikwazi ukuheha iphinde icoshe izingcezu zamaphepha ngenkathi iphikisa noma yiziphi ezinye izibaya okungenzeka ukuthi nazo zifakwe ugesi. Ubumbano namandla kuxhomeke ezintweni zokwenziwa, ebusweni maholoholo, lokushisa, ubunzima, kanye nezinye izakhiwo zamaminerali.
Njengoba uhlobo ngokuhlukana electrostatic, Ukwahlukaniswa kwe-triboelectric kuyasiza ekucutshungweni kwe-ore ngoba kungathola izihlabathi ezinhle kakhulu zamaminerali kunezinye izindlela. I isihlukanisi STET tribo-electrostatic ibhande isihlukanisi sekufakazelwe ukuthi kuzuzise ngempumelelo izinto zombili zokuvikela nokuvikela. Ngoba ikwazi ukucubungula izinto ezinobukhulu bezinhlayiyana ezisuka cishe 300 μm ukuba ngaphansi kuka 1 μm, lobu buchwepheshe budlulisela kakhulu uhla lwezinto ezisebenzayo ezedlula lezo zabahlukanisi abavamile be-electrostatic.
Kungani Khetha ST Izinsiza kusebenza & Ubuchwepheshe For Amaminerali Akho Ngokwahlukana Izinsiza kusebenza?
Uma ufuna okokusebenza okuhle kakhulu okwehlukanisa amaminerali embonini, ST Izinsiza kusebenza & ubuchwepheshe LLC (STET) ungumholi ku umkhakha wokwehlukanisa amaminerali elise Needham, Massachusetts. I-tribo-electrostatic belt separator yethu ihlinzeka ngenqwaba yezinzuzo ngaphezulu kwezinqubo zendabuko ezimanzi.
Ama-Separator ethu e-Triboelectrostatic azuza izinhlayiya ze-micron-size ngendlela eyomile ngokuphelele. Akudingi izinto ezengeziwe, iqeda isidingo sokomiswa, futhi ngoba isebenza ngaphandle kwamanzi noma amakhemikhali, akakhi amanzi angcolile noma ukungcola komoya Xhumana nathi namuhla ukuthola eminye imininingwane.
