摘要:
为了查明缅甸实皆省某金矿工艺矿物学特征,采用X射线衍射仪(XRD)、扫描电子显微镜(SEM)和化学分析等技术手段,系统研究原矿化学组成、矿物组成、粒度分布、金物相、单体解离度和矿石结构构造。结果表明:①原矿金品位为5.13×10-6,为主要有价元素。②矿石具自形晶粒结构,块状、斑杂状和浸染状构造,矿物组成简单。其中,金属矿物主要为黄铁矿,含少量黄铜矿、磁铁矿和斑铜矿,脉石矿物主要为石英、斜长石、方解石、绿泥石和白云母。③矿石中金易单体解离,重矿物中金分布率为3.94%,以单体金形式存在,金成色较好(大于93%),呈角粒状、块状、片状和圆片状;非重矿物中大部分金也已单体解离,游离金分布率为92.68%,包裹金分布率为3.38%。④细粒级矿石中金的单体解离度也比较高,-0.074 mm粒级中单体金含量为98.72%,连生体金含量为1.28%,各粒级中金的富集现象不明显。因此,重选—全泥氰化、浮选和重选—浮选等工艺均能有效回收矿石中金。
