摘　　要：赤铁矿与含铁硅酸盐脉石矿物由于具有相近的可浮性而难以分选 ,为此采用一种小分子有机抑制剂羟基乙酸作为含铁硅酸盐脉石矿物———霓石的选择性抑制剂 ,在pH值为 4～ 5的介质条件下成功地实现了赤铁矿与霓石的有效浮选分离。通过对矿物在溶液中 ζ电位、药剂吸附量的测定以及理论分析 。It is difficult to separate hematite from iron containing silicate gangue due to their similiar flotability. However, at pH4～5 of medium their effective separation can be achieved using hydro acetic acid as the depressant for aegerine. The dcpressing effect of hydro acetic acid on aegerine is investigated through measurements of zeta potential and adsorbance and theoretical analysis.
