摘　　要：对原矿金品位14.9g/t的某地高硫原生金矿,开展了原矿直接氰化浸出、重选—金精矿氰化浸出、重选—金精矿焙烧—氰化浸出和浮选—金精矿氰化浸出等四种提金工艺流程的对比试验。结果表明,原矿直接氰化浸出是合理的提金工艺流程,其金浸出率可达86.85%。Several series of contrast tests of technological flowsheets for extracting gold from a primary gold ore in Myanmar（ Burma）were carried out. The techno -econmic efficiency of four techmological flowsheets of direct cyanide leaching, gravity separation- cyanide leaching, gravity separation -roasting -cyanide leaching and flotation - cyanide leaching was compared in detail. The test results showed that direct cyanide leaching is a reasonable tech- nological flowsheet for extracting gold from this kind of primary gold ore, the leaching rate of gold can reach 86. 85%.
