硕士研究生孙水裕采用氧化剂双氧水(H_2O_2)作抑制剂,实现了人工和天然的Cu—pb混合精矿的选择性浮选分离。通过静电位测定、线性电位扫描、电位控制下的浮选实验和接触角测定,以及小幅度三角波电位法测定界面微分电容等一系列化学测试技术,详细研究了H_2O_2的抑制机理。结果表明,当H_2O_2浓度控制在(1 Master graduate student Sun Shuiyu used oxidant hydrogen peroxide (H 2 O 2) as inhibitor to achieve the selective flotation separation of artificial and natural Cu-Pb mixed concentrates. A series of chemical testing techniques, such as electrostatic potential measurement, linear potential sweep, potential control flotation experiment and contact angle measurement, and small-amplitude triangular wave potential method to measure interface differential capacitance, were used to study the inhibition mechanism of H 2 O 2 in detail. The results show that when H 2 O 2 concentration is controlled at (1
