摘要
为了给低品位级菱镁矿石的选矿提纯提供参考,在去离子水和自来水浮选环境中考察了十二酸用量及钙镁离子对菱镁矿及白云石纯矿物浮选的影响。根据结果可知,在去离子水介质中,十二酸在一定浓度下可实现菱镁矿与白云石的分离;钙镁离子对菱镁矿与白云石的浮选分离有较大影响。
In order to provide reference for the beneficiation and purification of low grade magnesite ore,the effects of the amount of dodecanoic acid and the effect of calcium and magnesium ions on the flotation of magnesite and dolomite minerals were investigated in deionized water and tap water flotation.According to the results,in the deionized water medium,dodecanoic acid in a certain concentration can be achieved magnesite and dolomite separation; calcium and magnesium ions on the magnesite and dolomite flotation separation have a greater impact.
