Abstract This 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. The examinations show that all tested depressants reduce the collection ability of pyrite with K-butyl xanthate (KBX). Different 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. | Apstrakt U 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. Ispitivanja su pokazala da svi ispitivani reagensi deprimatori smanjuju sposobnost kolektiranja pirita kolektorom K-butil ksantatom (KBX). Najveći 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. |
