对现有企业进行挖潜改造是增加产量,提高经济效益的有效途径.河北省张全庄金矿原生产能力为125吨/日,选厂采用的工艺流程是混汞+浮选.多年来,生产指标一直不高,波动较大,金的选矿回收率只有70～80%,尾矿金品位均损失在1.2克/吨以上,生产实践证明:原流程已不适合不断变化的矿石性质.为了扩大生产规模,进一步提高
The existing enterprises to tap the potential transformation is to increase production and improve economic efficiency is an effective way Zhangquanzhuang gold mine in Hebei Province, the original production capacity of 125 tons / day, the process used in the plant is amalgam + flotation. Over the years, production indicators Has been not high, volatile, gold dressing recovery rate of only 70 to 80%, tailings gold grade loss of 1.2 g / t or more, the production proved that: the original process is not suitable for the changing nature of ore.In order to expand production Scale, to further improve
