摘要
在黄铁矿浮选中,使用抑制剂WHL-Y1可有效地降低精矿中MgO含量.通过工艺矿相研究及吸附量、Zata电位、红外光谱测定,研究了WHL-Y1的作用机理:WHL-Y1中的-P-OH离子可以与矿物表面的Mg2+(Ca2+)发生化学反应,增强不纯黄铁矿的亲水性,在浮选时使其受到抑制,较纯黄铁矿可以优先浮选分离.
In the flotation of pyrite, the MgO content of concentrate is reduced effectively by using the depressant WHL -Y1. In this essay, the mechanism of action of the WHL -Y1 is studied by recalls of technology mineralorgaphy, adsorption, Zeta - potential and FT - IR spectrum. -P-OH can react with Mg^2+ (Ca^2+) on mineral surface and intense hydrophilic of pyrite, therefore magnetite can be floated optionally in the flotation.
