Abstract

There was carried out the research of mechanism of operation of new reagent AMD (АМД) (1-phenyl-2,3-dimethyl-4-dimethylaminopyrazolone-5), which is intended for flotation separation of sphalerite and pyrite during the flotation of auriferous copper-zinc pyrite-containing ores. There are established the reasons of reagent AMD selectivity concerning sphalerite and pyrite in alkaline medium:
– capability of this compound for formation of stable hydrophobic complex compound with zinc on the sphalerite surface;
– oxidation of AMD by ferric iron ions on the pyrite surface with formation of hydrophilic oxidation products.
For the purpose of identification of compound, which was formed during the flotation on the sphalerite surface, there was synthesized the complex compound of AMD with zinc, which formation rate is increased in the presence of thiocyanate-ions. Identification was carried out, using the UV- and IR-Fourier spectroscopy. It is shown that pyrite surface can catalyze the oxidation of AMD by ferric iron ions with formation of hydrophilic oxidation product in alkaline medium and removal of hydrophilic oxidized films from the surface of pyrite particles in acid medium.

This work was carried out with the support of the grant of the President of Russian Federation “Scientific School of Academician V. A. Chanturiya” NSh-220.2012.5 (НШ-220.2012.5).

Authors express their gratitude to M. V. Ryazantseva, E. V. Koporulina and A. N. Krasnov for the help in carrying out of researches by methods of IR-Fourier, electronic and laser microscopy.
