Ukufakwa kwe-ore kuwumsebenzi wokukhiqiza olungiselela izinto zokusetshenziswa zokuncibilikisa insimbi kanye nemboni yamakhemikhali. Ukufakwa kwe-froth flotation sekuyindlela ebaluleke kakhulu yokucubungula amaminerali. Cishe zonke izinsiza zamaminerali zingahlukaniswa ngokusebenzisa ukufakelwa kwe-flotation.
I-Flotation okwamanje isetshenziswa kabanzi ekucubungulweni kwama-ore ensimbi ane-ferrous alawulwa yi-iron ne-manganese, njenge-hematite, i-smithsonite, ne-ilmenite; ama-ore ensimbi ayigugu njengegolide nesiliva; ama-ore ensimbi angenayo i-ferrous afaka phakathi ithusi, i-lead, i-zinc, i-cobalt, i-nickel, i-molybdenum, ne-antimony, njengamaminerali e-sulfide afana ne-galena, i-sphalerite, i-chalcopyrite, i-chalcocite, i-molybdenite, ne-pentlandite, kanye namaminerali e-oxide afana ne-malachite, i-cerussite, i-hemimorphite, i-cassiterite, ne-wolframite; amaminerali kasawoti angeyona insimbi afana ne-fluorite, i-apatite, ne-barite; kanye namaminerali kasawoti ancibilikayo afana ne-sylvite ne-rock salt. Iphinde isetshenziselwe ukuhlukaniswa kwamaminerali angeyona insimbi nama-silicates, kufaka phakathi amalahle, i-graphite, i-sulfur, idayimane, i-quartz, i-mica, i-feldspar, i-beryl, ne-spodumene.
I-Flotation iqoqe ulwazi oluningi emkhakheni wokucubungula amaminerali, kanye nentuthuko eqhubekayo kwezobuchwepheshe. Ngisho namaminerali asezingeni eliphansi futhi ayinkimbinkimbi ngokwesakhiwo ayebhekwa njengangasetshenziswa ezimbonini manje angatholakala futhi asetshenziswe (njengemithombo yesibili) ngokusebenzisa i-flotation.
Njengoba izinsiza zamaminerali ziya ngokuya zincipha, njengoba amaminerali awusizo esatshalaliswa kahle futhi ngendlela ehlukile kuma-ore, ubunzima bokuhlukaniswa buyanda. Ukuze kuncishiswe izindleko zokukhiqiza, izimboni ezifana ne-metallurgy namakhemikhali zidinga amazinga aphezulu ekhwalithi kanye nokunemba kwezinto zokusetshenziswa ezicutshungulwayo, okungukuthi, imikhiqizo ehlukanisiwe.
Ngakolunye uhlangothi, kunesidingo sokuthuthukisa ikhwalithi; ngakolunye uhlangothi, ukuntanta kukhombisa izinzuzo ngaphezu kwezinye izindlela ekubhekaneni nenselele yamaminerali acwebezelayo okunzima ukuwahlukanisa. Sekuyiyona ndlela yokucubungula amaminerali esetshenziswa kakhulu futhi ethembisayo namuhla. Ekuqaleni isetshenziswa kumaminerali e-sulfide, ukuntanta kuye kwanda kancane kancane kwaba amaminerali e-oxide, amaminerali angewona awensimbi, nabanye. Njengamanje, izigidigidi zamathani amaminerali acutshungulwa ngokuntanta emhlabeni wonke minyaka yonke.
Emashumini eminyaka amuva nje, ukusetshenziswa kobuchwepheshe bokuntanta akusagcini nje ngobunjiniyela bokucubungula amaminerali kodwa kuye kwanda kwaze kwaba ukuvikelwa kwemvelo, ukusansimbi, ukwenza amaphepha, ezolimo, amakhemikhali, ukudla, izinto zokwakha, imithi, kanye ne-biology.
Isibonelo, i-flotation isetshenziselwa ukubuyisa izingxenye eziwusizo emikhiqizweni ephakathi ye-pyrometallurgy, i-volatiles, kanye ne-slags; ukubuyisa izinsalela ze-leach kanye nemikhiqizo evuvukele ku-hydrometallurgy; ukususa iphepha eliphinde lasetshenziswa kanye ne-fiber ekubuyiselweni koketshezi lwe-pulp embonini yamakhemikhali; kanye nokukhipha uwoyela onzima ongcolile esihlabathini esiseceleni komfula, ukuhlukanisa ukungcola okuncane okuqinile, ama-colloid, amabhaktheriya, kanye nokungcola kwensimbi okulandelwayo emanzini angcolile, okuyizinto ezisetshenziswayo ezivamile kubunjiniyela bezemvelo.
Ngokuthuthuka kwezinqubo nezindlela zokuntanta, kanye nokuvela kwama-reagent amasha futhi asebenzayo kanye nemishini yokuntanta, ukuntanta kuzothola ukusetshenziswa okubanzi ezimbonini nasemikhakheni eminingi. Kubalulekile ukuqaphela ukuthi ukusetshenziswa kwezinqubo zokuntanta kuhilela izindleko zokucubungula eziphakeme ngenxa yama-reagent (uma kuqhathaniswa nokuhlukaniswa kwamagnetic kanye namandla adonsela phansi); izidingo eziqinile zosayizi wezinhlayiya zokudla; izici eziningi ezithonya enkambisweni yokuntanta, ezifuna ukunemba kobuchwepheshe obuphezulu; kanye namanzi angcolile aqukethe ama-reagent asele angalimaza imvelo.
