    Abstract: A mineral separation process includes wet-grinding the ore to liberation of minerals, oxidizing the slurry using air, hydrogen peroxide or other oxidants and floating the valuable minerals at a pH between about 9.0 and 10.0 with a xanthate as collector, and a combination of a polyamine and a sulfur containing species as depressants for arsenide minerals. This depressant suite effectively depresses the flotation of arsenide minerals with no effect on the flotation of the valuable minerals.

    Abstract translation: 矿物分离过程包括将矿石湿法研磨以释放矿物质,使用空气,过氧化氢或其它氧化剂氧化浆料,并在约9.0至10.0之间的pH下以黄原酸盐作为收集器漂浮有价矿物质,以及 多胺和含硫物质作为砷化物矿物的抑制剂。 这种抑制剂套件有效抑制了砷化物矿物的浮选,对有价值矿物的浮选没有影响。
