内蒙古翁牛特旗硐子矿区铅锌矿矿石质量分析及选矿工艺流程的选择

Lead-zinc Mine in Inner Mongolia Wengniute Yindongzi Ore Beneficiation Process Quality Analysis and Selection

硐子矿区铅锌矿位于内蒙古翁牛特旗广德公镇境内,矿区位于硐子—小营子铅锌银多金属成矿带西段,属中温热液裂隙充填交代脉状铅锌矿床。矿体受近东西向断裂、岩体接触带等复合构造控制,主矿体长度3 698 m,延深695 m,平均厚度2.07 m,矿体呈脉状为第Ⅰ勘查类型,利用光、薄片及组合分析等方法了解矿石结构、构造及矿物构成,查明矿石中有益组份为Pb、Zn、Ag、Cu、S,其中Ag、Cu、S元素达到铅锌矿伴生组分要求,有害元素As含量低,对选矿没有影响。矿石类型为硫化矿石,比较易选并推荐选矿工艺流程。

DongziPb-Zn deposit is located in Guangdegong town, Wenniute county the western part of Dongzi-XiaoyingziPb-Zn-Ag polymetallic mineralization It belongs to epithemlal- mesothemlalfractre-filled vein type deposit. The occmTence of the ore body is controlled by nearly east-west trend fault and contract boundary of the fommtion and intrusion. The main ore body is with the length of 3 698 m, with depth of 695 m and average thickness of 2.07 m. It classified as prospecting type I . Respectively, we study the ore textre in structre and mineral composition by the rock and ore slices. Geochemically, Pb, Zn, Ag, Cu, Selements are the beneficialcomponents in this deposit. Meanwhile, the content of Ag, Cu and S elements have reachedassociated component. The content of hamfful element is very low, which has no effect to ore dressing. Ore types is sulfide, which is easier to dressing. It is recommended for the beneficiation process.
