Method for treating tailing slurries with Caro's acid |
摘要 |
A process for treating precious metal tailing slurries with Caro's acid, in which the Caro's acid is accompanied by reduced amounts of Caro's acid mist, is disclosed. The hot Caro's acid-containing mixture, formed by reaction of concentrated sulfuric acid and hydrogen peroxide, is quenched with water to reduce or eliminate the Caro's acid mist. The resulting cooled and diluted mixture is introduced into a precious metal tailings slurry to reduce the amount of cyanide values in the slurry.
