It showed from experiments that the best approach to the treatment of fine grained disseminated gold ore was hot press oxidation of flotation concentrate of pyrite followed by cyanide leaching.
试验结果表明：对含金黄铁矿精矿进行压热氧化—氰化浸出，是处理该微细粒浸染型金矿石较有效的方法。
The average leaching recovery of gold reaches 86.01% from high grade raw ore and flotation concentrate of gold in pilot test.
半工业试验对浮选金精矿和高品位原矿平均金浸出率达86．01％。
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.
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。
