摘要
控制焙烧条件,使金精矿中As、Sb、S、C有效脱除,其中的金表露。焙烧矿磨细至0 041mm以下86%以上,采用常规氰化浸出,金浸出率达92 13%,砷以三氧化二砷形式回收。
Controling the condition of roasting,arsenic sulfur stibium carbon particles are selectiverly removed,the roasted ore is ground to 86%-40?μm were treated in ordinary leaching process by cyamid,the gold leaching rate is 9213%
