Iyini inzuzo ye-flotation?

I-Flotation, eyaziwa nangokuthi i-froth flotation, iyindlela yokucubungula amaminerali ehlukanisa amaminerali abalulekile kumaminerali e-ganggue endaweni esibonakalayo eqinile ye-gas-liquid-solid ngokufaka umehluko ezindaweni ezingaphezulu zamaminerali ahlukahlukene. Kuphinde kubizwe ngokuthi "ukuhlukaniswa kobuso obuhlangene." Noma iyiphi inqubo esebenzisa ngokuqondile noma ngokungaqondile izixhumanisi zesigaba ukuze ihlukanise izinhlayiya zamaminerali ngokusekelwe kumehluko wezakhiwo zazo ezihlanganisa ubuso ibizwa ngokuthi ukuntanta.

Izakhiwo ze-mineral surface zibhekisela ezicini ezingokoqobo namakhemikhali zezinhlayiya zamaminerali, njengokumanzisa kwendawo, izakhiwo zikagesi ezingaphezulu, izinhlobo zamabhondi amakhemikhali kuma-athomu angaphezulu, ukugcwala kwamanzi, kanye nokusebenza kabusha. Izinhlayiya ezihlukene zamaminerali zibonisa izakhiwo ezihlukile ezingaphezulu, futhi ngokusebenzisa lo mehluko ngosizo lwezindawo zokuhlangana, ukuhlukaniswa kwamaminerali kanye nokunothisa kungafinyelelwa. Ngakho-ke, inqubo yokuntanta ibandakanya ukusebenzisana kwegesi, uketshezi, nezigaba eziqinile kusixhumi esibonakalayo.

Izakhiwo ze-mineral surface zingashintshwa ngokungenelela okwenziwayo ukuze kwandiswe umehluko phakathi kwamaminerali abalulekile namaminerali e-ganggue, ngaleyo ndlela kube lula ukuhlukana kwawo. Lapho i-flotation, ama-reagents e-flotation avame ukusetshenziselwa ukuguqula ngokuzenzakalelayo izakhiwo ezingaphezulu kwezimbiwa, ukuthuthukisa umehluko phakathi kwamaminerali, futhi andise noma ehlise i-hydrophobicity yendawo yamaminerali. Lokhu kuvumela ukulungiswa nokulawulwa kokuziphatha kwe-mineral flotation ukuze kuzuzwe imiphumela engcono yokuhlukanisa. Ngakho-ke, ukusetshenziswa nokuthuthukiswa kobuchwepheshe be-flotation kuhlobene kakhulu nokusetshenziswa kwama-reagents e-flotation.

Ngokungafani namapharamitha aphathekayo afana nokuminyana kanye nokuba sengozini kazibuthe, okunzima ukuwashintsha, izakhiwo ezingaphezulu zezinhlayiya zamaminerali zingashintshwa kalula ngokungenelela komuntu ukuze kudaleke umehluko ohlangabezana nezidingo zokuhlukana. Ngenxa yalokho, i-flotation isetshenziswa kabanzi ekuhlukaniseni amaminerali futhi kuvame ukubizwa ngokuthi "indlela yokucubungula amaminerali jikelele." Isebenza kakhulu futhi isetshenziselwa kakhulu ukuhlukaniswa kwezinhlayiya ezinhle kakhulu nezinhle kakhulu, okwenza kube enye yezindlela eziguquguqukayo nezisebenza kahle kakhulu ekucutshungulweni kwamaminerali.
