Abstract

Abstract:

According to the mineralogical characteristics of refractory gold concentrate containing high arsenic and sulfur，we propose a sec-roasting pressure acid leaching combined pretreatment process，and focus on the impact of the process on the removal effect for arsenic，sulfur and iron.The results show that after a roasting of refractory gold concentrate，then by two stage roasting under the conditions of calcination temperature 700 ℃ and roasting time 120 min，we obtain that As content is only 0.51% and S content is 0.34% in calcine.At the same time，the removal rate of As，S and Fe are more than 95% by pressure acid leaching，and achieve good results.

Key words: oxidation pretreatment, process mineralogy, energy spectrum analysis, pressure acid leaching, gold concentrate
