中文摘要: 采用两段焙烧——焙砂水淬（稀酸介质）——氰化工艺从某含砷难处理金精矿中提金，提取率可达92.2％，而采用常规的焙烧——氰化浸出工艺只能达到84．5％。对焙砂及氰化渣的矿物学研究表明，残留于渣中的大多数金均以超细的不可见金粒的形式为Fe2O3相包裹，因此，自该类型精矿中充分回收金的前提条件是尽可能破坏Fe2O3相。
Abstract:The gold recovery can reach to 92.2% from an arsenic-bearing refactory gold concentrate as by means of the two stage roasting-quenching(in the dilute acid solution)-cyaniding process,otherwise,only will be 84.5% under the routine roasting-cyaniding condition.The mineralogical study on the calcine and cyaniding residue indicates that the most gold remained in residue is enclosed by Fe_2O_3 with the ultrafine and invisible par- ticle form,thus the promise to recover fully the gold from this species concentrate is to destroy the Fe_2O_3 phase as full as possible.
