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。

Primary gold ore from Bangi, Guizhou, belongs to a clastic-type, finely disseminated, refractory particles. It is difficult to extract gold from the ore by cyanide infusing.
