甘肃陇南山区低品位氧化金矿的开发利用

The development and utilization of low-grade oxidized of the gold deposit in Gansu Longnan mountain regions

甘肃陇南山区分布着较为广泛的低品位氧化金矿 ,其特点是带状分布、规模大、品位低。可采用就地产金方案 (池浸、堆浸氰化提金工艺 ) ,投资少、见效快 ,当年投资当年还本 ,投资利润率高 ,具备开发利用的可行条件。

More extensive low grade oxidized deposits of gold are dispersed over Longnan mountain regions in Gansu Province. Their characteristics are zonal distribution, large scale and low grade. Gold can be extracted by means of tank leaching, heap leaching and cyaniding, less capital and more quickly effective, realizing returns on an investment in just one year. The profit ratio of the capital is very high. They possess many feasible factors in the development and utilization.
