金矿开采和处理方法
摘要：
一种金矿开采和处理方法包括步骤：a.开采金矿后研磨获得金矿原料；b.在温度150‑200℃和总压力2500‑3500kPa下对重量为m的金矿原料进行处理，以生产出氧化过的固态矿物；c.将氧化过的固态矿物的3‑10％混合到另一重量为m的金矿原料中再次在温度150‑200℃和总压力2500‑3500kPa下进行处理以生产出氧化过的固态矿物，并重复该步骤c；d.将步骤b和c剩余的氧化过的固态矿物送入氧压为3000‑6000kpa的容器中进行氰化35‑60分钟以回收Au。本发明提高了Au的释出率和综合生产效率，减少了氰化钠的用量，降低了成本，高效环保。
摘要（英）：

Provided are a gold mining and processing method. The method comprises steps of: A. After gold ore are mined, grinding the gold ore to obtain a gold mine raw material; B. Processing a gold ore material of weight m at a temperature of 150-200 °C and a total pressure of 2500-3500 kPa to produce an oxidized solid mineral; C. Mixing 3%-10% of the oxidized solid mineral into another gold ore raw material of weight m and processing again at a temperature of 150-200 °C and a total pressure of 2500-3500 kPa to produce an oxidized solid mineral, and repeating the step C; D. Transferring the remaining oxidized solid mineral of steps B and C to a vessel having an oxygen pressure of 3000-6000 kPa for cyanation for 35-60 minutes to recover Au.
