through bacterial oxidation, the arsenic can be removed over 90% from concentrate ( the arsenic content can be reduced to 2%) the key point is that the oxidizability of the selected bacterial species on arsenical pyrite must be high.

经实验室详细研究，该精矿中的砷经细菌氧化处理后可脱除90%以上（即可使精矿含砷量由原近20%降至2%）。

the phase analysis of gold in high arsenic and sulfur containing mineral of somewhere in jilin province was made. the result showed that the gold in ore sample mainly occurred as that gold enclosed by arsenical pyrite and sulfide.

通过对吉林某地高砷高硫金矿中金的相态分析研究，结果表明：该含金矿样中金主要以毒砂包裹金和硫化包裹金两种形式存在。
