PROCESSING METHOD OF GOLDEN-ANTIMONIAL-ARSENICAL SULPHIDE CONCENTRATES

摘要

FIELD: metallurgy. ^ SUBSTANCE: invention concerns method of golden-antimonial-arsenical sulphide concentrates processing. Method includes melting of concentrates into slag and matte with gold concentration in matte and with condensation of formed arsenious sublimate and gold extraction from melted matte by antimony melt. At that before gold extraction into matte after separation of slag it is introduced soda at stoichiometric ratio to sulphide of antimony 3:1. Gold extraction is implemented by means of feeding matte melt in disperse state under antimony melt. ^ EFFECT: increasing of complex extraction level of valuable components from concentrate, in increasing of gold extraction speed, in reduction of materials consumption and equipment level of sophistication. ^ 4 cl, 1 ex
