锰银矿物质组成考察及银的赋存状态研究

锰银矿具有物质组成复杂,矿块浸染严重,岩矿鉴定困难的特点。为查清矿样的矿物组成及银的赋存状态,采用光谱;化学;热分析;X射线衍射和电子探针等分析测试手段开展研究工作,取得满意结果。不仅查清了锰银矿样的主要锰矿物和矿物种类,银在矿样中的赋存状态以及银与锌、铅、铁、铅、硫、砷的共生关系。并且表明使用仪器进行综合分析测试是深入开展工艺矿物学研究的有效方法。

Investigation on Composition of Mn - Ag minerals and the Host Occurrence of Silver

silver manganese ore features complex compositions,heavy impregnation and difficulties in analysis.In order to investigate the mineral composition and host occurrence of silver,the methods of spectrographic, chemical,heat analysis,X-ray diffraction and other methods have been applied and reached good results.The main types of manganese ore the host occurrence of Ag and other metals such as Zn,Fe,Pb,S,As have been found out through above mentioned methods.It is also proved that the complex test using meters and instruments is very useful in mineralogical research.
