ARSENOPYRITE NITRIC ACID LEACH FOR GOLD RECOVERY |
摘要 |
A process for the hydrometallurgical recovery of gold from arsenical pyrite concentrate. The process comprises decomposing the concentrate by using a leach composed of higher valence nitrogen oxides present in acidic solution; subjecting the decomposed product to a solid-liquid separation to produce a residue and a liquid fraction; recovering gold from the residue by conventional means; and precipitating dissolved arsenic, iron and sulphur from the liquid fraction before recycling the liquid fraction in the process. |
