四川省平武金矿250升采金船于1989年建成,是我国处理巨砾含量大(>5%)的典型砂金矿山之一.投产以来,由于对巨砾的处理工艺还不成熟,巨砾的影响致使其实际生产能力只有设计能力的20～30%,各项选别指标也很低,主选设备回收率只有50%左右.虽然经过了几次流程改造(主要是主选设备的改造),但使用效果仍不理想.
The 250-hectare gold mining vessel at Pingwu Gold Mine in Sichuan Province was completed in 1989. It is one of the typical sand-gold mines with large boulder content (> 5%) in China since its inception.As a result of the immature boulder processing technology, Gravel impact of its actual production capacity of only 20% to 30% of design capacity, the various sorting index is very low, the main election equipment recovery rate of only about 50% .Although after several process improvement (mainly the main equipment Transformation), but the effect is still not ideal.
