摘　　要：某含砷硫铜金精矿用HOPF-防膜剂预处理3—5h后，氰化浸出尾渣中金品位从3．5—4．3g／t下降至0．7—1．2g／t。在氰化过程中，金精矿中的一些单体金粒表面上形成的红褐色薄膜得到抑制，缩短了氰化浸出时间，提高了金浸出率。After 3 - 5 hours＇ pretreatment with HOPF film-prevention reagent, the gold grade in the cyanidation slag of a certain copper-gold concentrate containing arsenic and sulfur reduced from 3.5 - 4.3g/t to 0.7 - 1.2g/t. In the cyanidation process, the henna film on some monomer gold was restrained, and as a result, the leaching period was shortened and the recovery rate was enhanced.
