The open pit areas are surrounded by an array of sculpted tailings ponds and mine dump areas; these receive mine waste rock for storage and later leaching for further recovery of metals.

露天矿坑周围是一些开挖尾料的堆弃池和废矿垃圾场。储存在这些地方的废弃矿石，稍后经过过滤可以深入提取其中的金属。

Using the existing open pit, the stripping and mining site is rationally adjusted, and conditions are created for realizing the inner dump and extending the open pit service life of Gushan Iron Mine.

利用现有的露天采坑，合理调整采剥部位，创造条件实现内部排土，延长了姑山铁矿露天采场的服务年限。
