Sažetak
Razlog za gubitak dijamanata u procesu flotiranja je zato što su kristali dijamanata na ulazu u proces obloženi hidroksidima i karbonatima. Predložen je kombinovan model da bi se putem termalnog i elektrohemijskog razaranja mineralne obloge povratila hidrofobnost dijamanata. Ova metoda predviđa da će se količina minerala koji oblažu površinu dijamanta smanjiti 3 do 10 puta u fazi kondicioniranja u procesu flotiranja. Tehnološka istraživanja su pokazala da korišćenjem proizvoda elektrolize bez dijafragme recirkulišuće vode, uz termičku obradu ulaznog proizvoda procesa flotiranja, omogućava povećanje iskorišćenja dijamanata u koncentratu flotiranja od 76,5% do 83,7%.
