中文摘要: 某金矿黄铁矿含量5.31%、氧化率6.02%,直接氰化金浸出率仅27.78%,属典型的低品位硫化物包裹型难处理金矿。为评估生物堆浸预氧化工艺对该矿石的工业化应用前景,开展了直接氰化浸出试验、生物搅拌预氧化试验和生物柱浸试验,考察了黄铁矿氧化率和金浸出率的关系以及温度对黄铁矿氧化率和金浸出率的影响。生物柱浸试验获得良好指标：原生矿破碎至P₈₀=5.5mm,在室温条件下(8-30℃)预氧化221天后,黄铁矿氧化率62.7%,金的浸出率为52.3%,氰化渣金品位为0.47g/t,较直接氰化浸出(金浸出率27.78%)金浸出率提高34.92个百分点。

Abstract:A gold ore with high pyrite content (5.31%) and low oxidation rate (6.02%), the ore is cyanide directly and the gold leaching rate is only 27.78%, which belongs to a typical a low grade refractory sulfidic gold-bearing ore. In order to evaluate the industrial application prospect of bio-preoxidation heap leaching process, direct cyanide leaching test, bio-stirring pre-oxidation test and bio-column leaching test were carried out to investigate the relationship between pyrite oxidation rate and gold leaching rate and the effect of temperature on pyrite oxidation rate and gold leaching rate. The results of bio-column leaching test showed that under the conditions of P₈₀=5.5mm and at room temperature (8-30 ℃) , about 52.3% of the pyrite was oxidized after 221 days, the leaching rate of gold came to 62.70%, which was 34.92% higher than that of direct cyanide leaching (27.78%), and the gold grade of leaching residue can be decreased to 0.47 g/t.
