前言有色金属小型矿山,一般是指采矿规模为600T/日以下的矿山企业,矿石年开采量一般在20万吨以下。建设小型矿山的地质资源规模,一般为小型矿床,但在某些情况下,大中型矿床经过初步勘探后,为了充分利用地下资源,促进大型矿山早日建成,也可以先期建设一个小型矿山,进行试生产,为解决将来大厂生产时的技 Preface Non-ferrous metal small mines, generally refers to the mining scale of 600T / day below the mining enterprises, ore mining volume is generally 200,000 tons or less. The scale of geological resources for the construction of small mines is generally small, but in some cases, preliminary exploration of large and medium-sized mines, in order to make full use of underground resources and promote the early completion of large-scale mines, may also be the first phase of construction of a small-scale mine Production, in order to solve the future production of technology manufacturers
