Abstract

Abstract:

A detailed mineralogy process study of a cyanide residue was performed，and the valuable metal elements is gold with the content of 2.51×10-6，which is mainly contained in pyrite and arsenopyrite.Single factor flotation test was performed according to property of mineral ore.Eventually，achieving the grade of gold concentration is18.70×10-6 and recovery is 70.18% in suitable flotation conditions by adding CuSO4，ammonium dibutyl dithiophosphate and buylxanthate，whose dosage are 150×10-6，70×10-6 and 100×10-6，respectively，into the pulp in the test and cyanide residue without grinding，CN- excluded by H2SO4，and the pH of pulp is 6.5，and also performing one roughing，two scavenging and three times cleaning.

Key words: cyanide residue, gold, pyrite, flotation technology
