河北东梁金矿床地质特征及开发利用探讨

Geological Features and Exploitation of Dongliang Gold Deposits in Eastern Hebei

东梁金矿床位于河北省宽城县,是火山机构引发的环形断裂控制的金矿床,主矿体长1700 m,平均厚度24.72 m,黄金资源储量19.53 t,平均品位1.55 g/t,是个中型低品位金矿床,该矿适合按不同厚度分级圈定进行坑采,才能有效控制矿石的贫化率,保证矿石的入选品位,不适合露天开采和常规意义上的坑采。

Dongliang gold deposit is located in Kuancheng County , Hebei province, is controlled by ring-type fault belt in- voked by volcano mechanics, with main orebody length of 1700 meters, average thickness of 24.72 meters, gold resource reserves of 19.53 tons and average grade of 1.55g/t, is a medium-scale low-grade gold deposit bed. The mine is fit for pit mining by delineation of different orebody thickness grading to effectively control ore dilution and to guarantee feed grade of benefication.
