Abstract

The aim of this work was to study floatability of the mineral sheelite from mine 'Rudnik', central Serbia. Flotation tests of the mineral in a Hallimond tube cell were carried out in four different types of water, namely: tap water, distilled water, rain water and spring water. All types of water had different hardness and conductivity as well as natural pH values. It was found that the flotability of mineral scheelite depends on the hardness and electro-conductivity of the chosen type of water as well as on Ca2+ content. Also, it was found the floatability of mineral depends on the scheelite particle size fraction used in microflotation experiments. Presented results may be useful for proper selection of type of water, as well of the type of reagents used in flotation processes.

Summary

NAUČNI RAD

ZETA-POTENCIJAL I FLOTABILNOST MINERALA ŠELITA U RAZLIČITIM TIPOVIMA VODA Deo 2. Nađeno je da flotabilnost minerala šelita zavisi od ukupne tvrdoće i elektroprovodljivosti izabranog tipa vode, a posebno od sadržaja Ca2+ u tim vodama. Takođe je nađeno da flotabilnost minerala šelita zavisi od korišćene uske klase krupnoće šelita u mikroflotacijskim eksperimentima u Halimondovoj ćeliji. Izbor vode je podjednako važan kao što je važan i izbor reagensa koji se mogu koristiti u flotacijskom procesu za dobijanje optimalnih rezultata flotacijske koncen minerala šelita. Utvrđivanje uticaja različitih prirodnih voda (različit pH, ukupna tvrdoća, elektroprovodljivost itd.) na vrednosti zeta-potencijala šelita bio je predmet ispitivanja u Delu 1 ovoga rada. Posledično, njihov uticaj na flotabilnosti šelita u tim vodama, a radi definisanja najpovoljnijeg tipa vode za flotaciju šelita, predmet je ispitivanja u Delu 2 ovoga rada
