I-Flotation, eyaziwa nangokuthi i-froth flotation noma i-mineral flotation, iyindlela yokwenza inzuzo ehlukanisa amaminerali abalulekile kumaminerali e-ganggue endaweni esibonakalayo eqinile ye-gas-liquid-solid ngokusebenzisa ukuhluka kwezakhiwo ezingaphezulu zamaminerali ahlukahlukene ku-ore. Kuphinde kubizwe ngokuthi "ukuhlukaniswa kobuso obuhlangene." Noma iyiphi inqubo esebenzisa ngokuqondile noma ngokungaqondile izici zobuso obuhlangene ukuze kuzuzwe ukuhlukaniswa kwezinhlayiyana ngokusekelwe kumehluko wezimpawu ezingaphezulu zezinhlayiya zamaminerali ibizwa ngokuthi i-flotation.
Izakhiwo ezingaphezulu zamaminerali zibhekisela ezicini ezibonakalayo namakhemikhali ezinhlayiya zamaminerali, njengokumanzisa kwendawo, ukushaja kwendawo, izinhlobo zamabhondi amakhemikhali, ukugcwala kwendawo, kanye nokusebenza kabusha kwama-athomu angaphezulu. Izinhlayiya ezahlukene zamaminerali zibonisa ukuhluka okuthile ezindaweni zazo ezingaphezulu. Ngokusebenzisa le mehluko ngokusebenzisa ukuxhumana phakathi kobuso, ukuhlukaniswa kwamaminerali kanye nokunothisa kungafinyelelwa. Ngakho-ke, inqubo ye-flotation ihilela i-interface ye-gas-liquid-solid yezigaba ezintathu.
Izakhiwo ezingaphezulu zamaminerali zingashintshwa ngokwenziwa ukuze kuthuthukiswe umehluko phakathi kwezinhlayiya zamaminerali ezibalulekile kanye ne-ganggue, ngaleyo ndlela kube lula ukuhlukana kwazo. Lapho i-flotation, ama-reagents ngokuvamile asetshenziselwa ukuguqula izakhiwo ezingaphezulu zamaminerali, akhulise ukungafani kuzici zawo ezingaphezulu futhi alungise noma alawule i-hydrophobicity yawo. Lokhu kukhohlisa kulawula ukuziphatha kokuntanta kwamaminerali ukuze kuzuzwe imiphumela engcono yokuhlukana. Ngakho-ke, ukusetshenziswa kanye nokuthuthuka kobuchwepheshe be-flotation kuhlobene kakhulu nokuthuthukiswa kwama-reagents e-flotation.
Ngokungafani nokuminyana noma ukuzwela kazibuthe—izakhiwo zamaminerali okunzima kakhulu ukuzishintsha—izakhiwo ezingaphezulu zezinhlayiya zamaminerali ngokuvamile zingalungiswa ngokwenziwa ukuze zenze umehluko odingekayo phakathi kwamaminerali ukuze kuhlukaniswe ngempumelelo. Ngenxa yalokho, i-flotation isetshenziswa kabanzi ekuzuzweni kwezimbiwa futhi kuvame ukuthathwa njengendlela yokuzuza umhlaba wonke. Isebenza ngempumelelo futhi isetshenziswa kakhulu ekuhlukaniseni izinto ezinhle nezinhle kakhulu.
