摘要
FIELD: metallurgy. SUBSTANCE: noble metals are leached with products of metabolism of heterotrophs. Leaching solution is used in form of aspartic acid with concentration of 4-8 g/l, and oxidizer is used in form of potassium permanganate. Solvent-to-oxidizer ratio is maintained within the range of 0.7:1 to 2:1. EFFECT: higher efficiency. 3 cl, 2 tbl
