摘 要：<正> Arsenic is often occured in sulphide gold-containing ores and concentrates. The principal minerals of these materials are arsenopyrite （FeAsS）, auripigment （As2S3）, realgar（As2S2） and lollingite （FeAs2）. In pyrometallurgical processing of raw materials, arsenic is sublimated mainly in the form of very toxic heavily trapped white arsenic contaminating dusts, sublimates and par
