Abstract
A method for determination of gold, lead, nickel, cobalt in a range of concentrations from mg/g to ng/g was developed. Method can be applied for determination of corresponding metals in ores, rocks and waste mining industry. Method consists of annealing, treatment with hydrofluoric acid and aqua regia followed by extraction (in the case of gold) di-n-octyl sulphide (DOS). Method was tested by certified reference material (8773-2006 РВ 3-8) and various rock samples Altai-Sayan folded area.
