I-Flotation, eyaziwa ngokuba yi-froth flotation, yindlela yokucubungula izimbiwa eyahlula iiminerali ezixabisekileyo kwiiminerali ze-gangue kwindawo yokudibanisa igesi-ulwelo-eqinileyo ngokusebenzisa umahluko kwiipropati zomphezulu weeminerali ezahlukeneyo. Ikwabizwa ngokuba "kukwahlulwa kwe-interfacial." Nayiphi na inkqubo esebenzisa ngokuthe ngqo okanye ngokungathanga ngqo ii-phase interfaces ukwahlula amasuntswana ezimbiwa ngokusekelwe kumahluko kwiipropati zazo zokudibanisa i-interfacial ibizwa ngokuba yi-flotation.
Iipropati zomphezulu weeminerali zibhekisa kwiimpawu zomzimba nezekhemikhali zeendawo zeeminerali, ezinje ngokumanzi komphezulu, iipropati zombane womphezulu, iintlobo zeebhondi zeekhemikhali kwiiathom zomphezulu, ukugcwala, kunye nokusabela. Iinqununu zeeminerali ezahlukeneyo zibonisa iipropati ezahlukeneyo zomphezulu, kwaye ngokusebenzisa olu mahluko ngoncedo lweendawo zokuhlangana, ukwahlulwa kweminerali kunye nokutyebisa kunokufezekiswa. Ke ngoko, inkqubo yokudada ibandakanya ukusebenzisana kwezigaba zegesi, ulwelo, kunye neziqinileyo kumphezulu wokudibana.
Iipropati zomphezulu weminerali zinokutshintshwa ngokungenelela okwenziweyo ukuze kwandiswe umahluko phakathi kweeminerali ezixabisekileyo kunye neeminerali ze-gangue, ngaloo ndlela kube lula ukwahlukana kwazo. Kwi-flotation, ii-reagents ze-flotation zihlala zisetyenziselwa ukuguqula iipropati zomphezulu weminerali ngokwenziwayo, ukuphucula umahluko phakathi kweeminerali, kunye nokwandisa okanye ukunciphisa i-hydrophobicity yeendawo zeeminerali. Oku kuvumela ukulungiswa kunye nokulawulwa kokuziphatha kwe-mineral flotation ukuze kufezekiswe iziphumo ezingcono zokwahlukana. Ngenxa yoko, ukusetyenziswa kunye nophuhliso lwetekhnoloji ye-flotation kunxulumene kakhulu nokusetyenziswa kwee-reagents ze-flotation.
Ngokungafaniyo neeparameters zomzimba ezifana noxinano kunye nokuthambekela kwemagnethi, okunzima ukuzitshintsha, iipropati zomphezulu wee-mineral particles zinokulawulwa ngokulula ngokungenelela komntu ukudala umahluko ohlangabezana neemfuno zokwahlukana. Ngenxa yoko, ukutyibilika kusetyenziswa kakhulu ekuhlukaniseni iiminerali kwaye kudla ngokubizwa ngokuba "yindlela yokucubungula izimbiwa jikelele." Isebenza kakhulu kwaye isetyenziswa kakhulu ekuhlukaniseni ii-microparticles ezincinci nezincinci kakhulu, nto leyo eyenza ibe yenye yezona ndlela zisebenzisekayo nezisebenzayo ekucwangcisweni kwezimbiwa.
