摘要
在酸（Ｈ２ＳＯ４、ＨＮＯ３－Ｈ２ＳＯ４）及碱（ＮａＯＨ、ＮＨ４ＯＨ、Ｃａ（ＯＨ）２）性介质中分别对合砷的难选难冶金矿（４．９ｇ／ｔＡｕ）进行了加压氧化预处理研究，表明金的氰化浸出率可由１５％提高到８５％。
In this paper the pretreatments of arsenical refractory gold ore with pressure oxidation process in an acid aqueous solution (H2SO4, HNO3-HNO3) and alkaline aqueous solution (NaOH, Ca (OH)2, NH4OH)have been shidied respectively. The experimental results show that the eganide leaching rate can be improved from 15%to over 85%by pretreatment of pressure oxidation.
