本文讨论了在稀土矿物浮选中pH对氟碳铈矿和独居石表面-电位、RE(Ⅲ)的水解、药液的化学性质及稀土矿物浮选的作用与影响。导出了稀土矿物浮选pH的理论计算式。计算结果表明,计算值与试验结果一致。
In this paper, the effects of pH on the surface potential and RE (Ⅲ) hydrolysis of bastnaesite and monazite, the chemical properties of the liquid and the flotation of rare earth minerals are discussed in the flotation of rare earth minerals. The theoretical formula of pH value of rare earth mineral flotation is derived. The calculation results show that the calculated values agree with the experimental results.
