METHOD OF EXTRACTING GOLD FROM MINERAL STOCK BEARING MINOR GOLD FRACTIONS

摘要

FIELD: metallurgy. ^ SUBSTANCE: invention relates to mineral stock processing and may be used for extracting gold fractions of grain size smaller than 0.07 mm. Proposed method comprises preparing water suspension with addition of flocculating agent. Damped ground paper bulk is added to said suspension, paper bulk features reduced moisture resistance and mineral component-to-bulk ratio making 1: 0.05. Then, mix is mixed in mixer for 10 s. After mixing, paper bulk is separated on sieve with mesh size not exceeding 0.2 mm. Now, paper bulk is rinsed to produce concentrate to be dried and fused. ^ EFFECT: higher efficiency, lower costs. ^ 1 ex
