n3Abstract: n3Sažetak:
n4This paper presents the results of the examination of depressing effect of cyanide salts type reagents (NaCN, K3[Fe(CN)6] and K4[Fe(CN)6]), as well as ferrous/ferric salts (FeSO4 and Fe2(SO4)3) on the floatability of pyrite in the presence of xanthate as collector. n4U radu su prikazani rezultati ispitivanja deprimirajućeg efekta reagenasa tipa cijanidnih soli (NaCN, K3[Fe(CN)6] i K4[Fe(CN)6]), kao i fero/feri soli (FeSO4 i Fe2(SO4)3) na flotacijska svojstva pirita u prisustvu kolektora tipa ksantata.
n5The examinations show that all tested depressants reduce the collection ability of pyrite with K-butyl xanthate (KBX). n5Ispitivanja su pokazala da svi ispitivani reagensi deprimatori smanjuju sposobnost kolektiranja pirita kolektorom K-butil ksantatom (KBX).
n6Different combinations of reagents FeSO4 and/or Fe2(SO4)3 with NaCN showed the greatest depressing effect on the pyrite, while the complex cyanide salts showed much less depressing effect on mineral. n6Najveći deprimirajući efekat na pirit pokazala je različita kombinacija reagenasa FeSO4 i/ili Fe2(SO4) sa NaCN, dok su kompleksne cijanidne soli pokazale znatno manji deprimirajući efekat na ovaj mineral.

n81. INTRODUCTION n81. UVOD
n9In industrial practice of flotation of sulphide lead-zinc and copper ores, pyrite, as a constant presented mineral in these ores, depresses in the various stages of selective flotation or it separates in concentrate. n9U industrijskoj praksi flotiranja sulfidnih olovo-cinkovih i bakrovih ruda, pirit, kao stalni pratilac ovih ruda, deprimira se u pojedinim fazama selektivnog flotiranja ili se pak izdvaja u zaseban koncentrat.
