| titleOfInvention | Method for improving biological oxidation speed of micro-fine particle fraction packaged refractory gold ore |
| abstract | The invention discloses a method for improving the biological oxidation speed of micro-fine particle fraction packaged refractory gold ores, belonging to the technical field of hydrometallurgy. The method comprises the following steps: (1) carrying out superfine grinding on the micro-fine particle fraction wrapped refractory gold ore in a grinding machine; mixing the superfine gold concentrate obtained in the step (1), feeding the mixture into a biological oxidation pretreatment system, and carrying out biological oxidation; (3) and (3) washing, size mixing and leaching the oxidation slag obtained in the step (2). The invention can solve the problem that the fine sulfide package is difficult to open, shorten the oxidation time, improve the biological oxidation speed and the mine throughput, does not change the prior biological oxidation process flow, has strong applicability, is convenient to implement and manage, and has better economic benefit and social benefit. |
