Ngokwemvelo, ngaphandle kwezinhlayiya zamaminerali ezifana namalahle, i-graphite, i-talc kanye ne-molybdente, ezinama-hydrophobic futhi ngokwemvelo amadiphozithi ama-hydrophilic, futhi okufanayo kuyiqiniso kumadiphozi egolide. Ukungezwa i-ejenti kungashintsha i-hydrophicity yezinhlayiya zamaminerali futhi ikhiqize i-hydrophobicity ukubenza baguqeke. Lo menti uvame ukubizwa ngokuthi umqoqi. Ukuqoqa ama-ejenti ngokuvamile abaqoqi be-polar kanye nabaqoqi abangewona ama-polar. Abaqoqi bePolar bakhiwa ngamaqembu ama-polar angasebenzisana nobubanzi bezinhlayiya zamaminerali namaqembu angewona ama-polar anomphumela we-hydrophobic. Lapho lolu hlobo lomqokeleli luhlotshiswe ngaphezulu kwezinhlayiya zamaminerali, ama-molecule alo noma ama-ion ahlelwe ngokulandelana, ngamaqembu ama-polar abheke phezulu kwezinhlayiya zamaminerali namaqembu okungewona ama-polar abheke ngaphandle kwe-hydrophobic, ngaleyo ndlela okwenza indawo yamaminerali intanta. . Igolide elihlotshaniswa nama-sulfide mineral imali enjengethusi, ukuhola, i-zinc, i-iron, njll, izinhlanganisela ze-organic thio zivame ukusetshenziswa njengabaqoqi ngesikhathi sokuthwebula. Isibonelo, i-Alkyl (ethyl, i-propylene, i-Butyl, i-DEDYL, njll.) Sodium dithiocarbonate (potassium), eyaziwa nangokuthi, eyaziwa ngokuthi yi-xanthate. Isibonelo, i-NAS2CH · och2 · ch3, lapho i-polymerallic ores ethwele i-polymeraltic ores, ethyl xanthate kanye ne-butyl xanthate asetshenziswa kakhulu. I-ALKYL Dithiophosphates noma usawoti wayo, njenge (Ro) 2pSSH, lapho r i-ALKYL GROUP, zaziwa kakhulu njengomuthi omnyama.
Umenzeli we-Foaming
Igolide elihlotshaniswa nama-sulfide mineral imali enjengethusi, ukuhola, i-zinc, i-iron, njll, izinhlanganisela ze-organic thio zivame ukusetshenziswa njengabaqoqi ngesikhathi sokuthwebula. Isibonelo, i-Alkyl (ethyl, i-propylene, i-Butyl, i-DEDYL, njll.) Sodium dithiocarbonate (potassium), eyaziwa nangokuthi, eyaziwa ngokuthi yi-xanthate. Isibonelo, i-NAS2CH · och2 · ch3, lapho i-polymerallic ores ethwele i-polymeraltic ores, ethyl xanthate kanye ne-butyl xanthate asetshenziswa kakhulu. I-ALKYL Dithiophosphates noma usawoti wayo, njenge (Ro) 2pSSH, lapho r i-ALKYL GROUP, zaziwa kakhulu njengomuthi omnyama. Usawoti we-Alkyl Dissulfide nosawoti we-Ester nabo bavame ukusetshenziswa abaqoqiwe ngama-Sulfide Mineral Deposits. Kungumqoqi osetshenziswa kakhulu wokugcwala kwe-polymerallic sulfide ama-ares wegolide, futhi uvame ukusetshenziswa kanye ne-xanthate. Ama-molecule abaqoqi abangewona ama-polar abahlukanisi, njengama-sulfur aqukethe ama-sulfur, kanti abaqoqi abangewona ama-polar bangamafutha e-hydrocarbon (amafutha angathathi hlangothi), njengopharafini, udizili, njll.
Ama-molecule asebenzayo angaphezulu kwamaqembu anama-hydrophilic kanye ne-hydrophobic akhishwe kahle esibonelweni somoya wamanzi, anciphisa ukungezwani komugqa wekhambi elinamanzi nokwenza umoya ogcwele amanzi ahlakazeke kalula kuma-bubble nama-bubble aqinile. Umenzeli we-Foaming kanye nomqoqi kuhlanganiswe ne-adcerb ebusweni bezinhlayiya zamaminerali, okwenza izinhlayiya zamaminerali zintanta. Ama-ejenti we-foaming asetshenziswayo afaka: uwoyela wephayini, owaziwa kakhulu njengo-Oyela 2, ama-Phenolic acijile axutshwe notshwala onamafutha, i-isomeric hexanol noma i-pungent utshwala, ama-ether acobles kanye nama-ether acobles kanye nama-ether acobles kanye nama-ether acobles kanye nama-ether acobles kanye nama-ether acoble.
Ama-aguqukayo angahlukaniswa izigaba ezinhlanu: (1) ukulungiswa kwe-PH. Isetshenziselwa ukulungisa i-PH ye-Slurry ukulawula izakhiwo ezingaphezulu kwediphozi yamaminerali, ukwakheka kwamakhemikhali kwe-slurry kanye nemibandela yamanye amakhemikhali ahlukahlukene, ngaleyo ndlela kuthuthukise umphumela wokufakelwa. Enqubweni yamakhemikhali, kuyadingeka futhi ukulungisa inani le-PH ye-Slurry. Okusetshenziswayo okuvame ukusetshenziswa kufaka phakathi i-lime, i-sodium carbonate, ne-sulfuric acid. Lapho ukhetha igolide, i-conditioners esetshenziswa kakhulu yi-lime ne-sulfuric acid. (2) Isishoshovu. Kungakuthuthukisa amandla okusebenza kwama-mineral deposits kanye nabaqoqi ukuze basebenze futhi bantanta okunzima kokuthambisa amaminerali amaminerali. I-Love-Copper ori equkethe i-ONE-Copper ori icushiwe bese iqhutshwa kusetshenziswa i-xanthate nabanye abaqoqi. .
Ukwenza isibonelo, kwinqubo yokuzikhethela encamelayo, i-lime isetshenziselwa ukucindezela i-pyrite, i-zinc sulfate kanye ne-sphalerite kusetshenziselwa ukucindezela amaminerali e-basue, njll., Kanye nezinto eziphilayo ezifana nesitashi ne-gum (i-tannin) zisetshenziswa njengabacindezeli ukufeza izinhloso eziningi. Inhloso yokuhlukaniswa kwensimbi kanye ne-flotation. (4) i-flocculant. Izinhlayiya ezinhle zezinhlayiya ezinamaminerali zibe izinhlayiya ezinkulu ukusheshisa ijubane lazo elandile emanzini; Sebenzisa i-Selective Flocculation ukwenza i-floccation-destiliming kanye ne-floccation-floccation. Ama-Flocculants asetshenziswa kaningi afaka i-polyamide nesitashi. (5) distriant. Kuvimbela ukuhlanganiswa kwezinhlayiya ezinhle ezimbiwa phansi futhi uzigcine esesimweni se-monomer. Umphumela wayo uhlukile ngokuhlukile kwaleyo ye-flocculants. Okuvame ukusetshenziswa kufaka ingilazi yamanzi, phosphate, njll.
