低品位资源在河西金矿区的开发利用实践

Development and utilization of low grade resources in Hexi Gold Mine Area

在对河西金矿区资源二次开发的基础上,根据目前国际市场的黄金价格,结合矿山生产成本,确定低品位矿的工业指标,对低品位矿体进行圈定,摸清矿区的低品位资源赋存情况,并研究现有生产系统和开采条件,对低品位进行开采回收利用,为探索建立黄金低品位资源综合利用的新模式提供了经验,为企业创造可观的经济和社会效益。

Based on the secondary development of resources in Hexi gold mine area,according to the current international market gold price,combined with the mine production cost,the industrial index of low-grade ore is determined,the low-grade ore body is delineated,the occurrence of low-grade resources in the mining area is found out,and the existing production system and mining conditions are studied to mine and recycle the low-grade ore,so as to explore the establishment of Yellow River Delta The new mode of comprehensive utilization of gold low-grade resources provides experience and creates considerable economic and social benefits for enterprises.
