摘要:

黄铁矿是最常见且最重要的载金矿物。根据黄铁矿的颜色、晶体形态和结构特征可初步判定其含金性。采用手标本观察、化学分析和显微镜下分析相结合的方法,通过对内蒙古敖汉旗岱王山金矿含金黄铁矿特征的系统归纳,总结了黄铁矿形态标型特征与矿石含金性的对应关系。结果表明:一般富金的黄铁矿多为浅黄色、黄色和暗黄色,而浅黄白色的黄铁矿含金量低;矿石中黄铁矿的含量与金品位呈正相关关系;五角十二面体含金性比立方体好;黄铁矿晶形复杂、自形程度低、粒度细且裂隙发育者含金性好;黄铁矿或其氧化物(褐铁矿)呈蜂窝状、条带状、浸染状和网脉状构造者含金性好。

Abstract:

Pyrite is the most common and important gold-bearing minerals in gold deposits.The color,crystal form and structure of pyrite can be used to evaluate the gold potentiality of ore.Through the method of combination of hand specimen observation,chemical analysis and microscopic analysis,based on the study of typomorphic characteristics of pyrite in Daiwangshan gold deposit,Aohanqi,Inner Mongolia,this paper summarized the typomorphic characteristics of pyrite with the gold potentiality of ore.The results show that the following typomorphic characteristics are very significant for prospecting:pyrite with rich gold is light yellow,yellow,dark yellow,but yellow white with low gold content;the content of pyrite and gold grade is positively related;gold-bearing properities of pyritohedron is better than the cube;the pyrite with complex crystal shape,subidiomorphic and xenomorphic,the fine grain,fracture development are gold enriched.Pyrite or its oxide (limonite) with vesicular,banded,disseminated,stockwork structure are gold enriched.

Key words: pyrite, gold deposit, crystal form, gold-bearing properities, pyritohedron, typomorphic characteristics
