Abstract

Метод за извличане на благородни метали от кисел богат разтвор, продукт от халогенно или хипохалитно изтичане на руда, който се състои в намаляване на ОРП на богатия извлек с използване на редуциращ агент в присъствието на кашести невъглеродни частици. Извлечени са депозити от благородни метали върху повърхността на частиците и обеднен разтвор, който в голяма част съдържа всички халогенни стойности на богатия разтвор под формата на натриев хлорид, натриев бромид или хипохалити. 10 претенцииA method for extracting precious metals from an acidic rich solution, a product of a halogen or hypochalite ore leak, which consists in reducing the ODP of the rich extract using a reducing agent in the presence of non-carbonaceous slurries. Precious metal deposits are extracted on the surface of the particles and a depleted solution, which in large part contains all the halogen values of the rich solution in the form of sodium chloride, sodium bromide or hypochalites. 10 claims
