美国矿业局科罗拉多丹佛研究中心目前正在研究一种地下采矿新方法──采场溶浸。在采场溶浸中,地下空场充满从围岩爆厂的破碎岩块或从矿山其他地方运来的矿石,然后将溶浸贫液施市在空场中的破碎矿石上,从中浸出金属。最后将浸出液收集后泵送至地表进行处理,回收目标金属。
The United States Department of Mines Denver Colorado Research Center is currently studying a new underground mining method ─ ─ stope leaching. In stope leaching, the underground airspace is filled with crushed rocks from the rock blasting plant or ore transported from other parts of the mine, and the leaching solution is then applied to the crushed ores in the open field to leach metal . Finally, the leachate is collected and pumped to the surface for treatment to recover the target metal.
