| titleOfInvention | A kind of method for innocent treatment of arsenic-containing gold concentrate biological pre-oxidation Cyanide Process slag liquid containing arsenic |
| abstract | The invention discloses a kind of method for innocent treatment of arsenic-containing gold concentrate biological pre-oxidation Cyanide Process slag liquid containing arsenic, comprise the following steps：(1) arsenic-containing gold concentrate is pre-oxidized with biological tank leaching process, obtains pre-oxidation ore pulp；(2) above-mentioned pre-oxidation ore pulp is subjected to separation of solid and liquid, obtains the first supernatant and the first underflow；(3) by the first supernatant preneutralization and then through separation of solid and liquid, the second supernatant and the second underflow are obtained；(4) after the second supernatant being carried out into 2~4h of the heavy solid arsenic of iron of goethite, separation of solid and liquid is carried out, obtains overflowing liquid and the 3rd underflow, overflowing liquid enters biological drill traverse process, the underflow of part the 3rd returns to the reaction unit of the solid arsenic of heavy iron as crystal seed, is arranged outside remaining the 3rd underflow；(5) the first underflow is subjected to cyanidation CIL, obtains ore pulp；(6) ore pulp obtained by step (5) is subjected to the solid arsenic of molysite aeration.The method of the present invention provides the necessary technical support for environment-friendly, high efficiency, low cost the exploitation of arsenic-containing gold concentrate. |
