一种从重砂中回收细粒金的方法。
The present invention relates to a recovery method of fine grain gold from heavy concentrate.
金矿物以自然金为主，可回收元素金为细粒金和微细粒金。
The native gold is main gangue minerals and it is fine particle and micro-fine particle.
金主要以镜下不可见的微细粒金为主，矿石中绢云母含量很高，矿石泥化严重，浮选回收率偏低。
The gold are mainly fine grained and invisible under microscope. The Muscovite content of the ore is high. The ores are extremely sliming so the flotation recovery rate is low.
另外，砂质单元金含量比细粒的粉砂岩和泥岩要高，从浊积岩序列的底部旋回至上部回金的含量降低并由不稳定到稳定等规律。
At other hand, the golden content of the sandstone is higher than that of fine grain siltstone and mudstone, and tends to decrease and stabilize upward in the turbidite sequence.
某高砷金矿石，金矿物粒度特别细，属微细粒以下金，金矿物以黄铁矿、砷黄铁矿、脉石包裹为主。
Gold mineral of some high arsenic is very fine, and it is inclused by.
自然金呈微细粒和显微细粒赋存于黄铁矿、毒砂及褐铁矿之中。
Native gold as fine grains and micro grains occurs in pyrite, arsenopyrite and limonite. Gold ore is intensively oxidized and characterized by low impurity and easily sorting.
金的载体矿物主要是毒砂，其次是黄铁矿，金以超微细粒和次显微金包裹于毒砂和黄铁矿中。
Gold-bearing minerals are mainly arsenopyrite, secondly pyrite. Gold grains are included in arsenopyrite and pyrite crystals in forms of ultra...
