In this research, an investigation of a process to selectively remove arsenic (As) and antimony (Sb) contained in enargite (Cu3AsS4) and tennantite/tetrahedrite ((Cu1,Fe)12(As,Sb)4S13) copper resources by leaching and precipitation were performed. First in the leaching process, the target was to selectively leach As/Sb and reduce their contents in the …

Electrolytic recovery of antimony from natural stibnite ore …
Antimony and arsenic were easily precipitated from sulphate solution as sulphides, in a form easy to filter. Boiling with concentrated H2SO 4 at the same time also causes complete dehydration of silicic acid, which is thus converted to a suitable form for quantitative precipitation. Any antimony trisulphate Sb2(SO4) 3 formed decomposes in water.
