磁流体动力分选
magnetohydrodynamic separation
C 1 1 1 Uti dongli fenxUan磁流体动力分选(magnetohydrodynami。Sep-aration)在均匀或不均匀磁场与电场联合作用下，在电解质水溶液中根据物料的密度、磁化率及导电率的差异进行分选的磁流体分选方法。磁流体动力分选是基于交叉的电场和磁场在电解质中所产生的电磁推力对物料的作用实现的。在外加交叉电场和磁场作用下，浸没在电解质溶液中的单位体积固体颗粒所受的作用力为 3(日一J).__二_r_____ f一(洲一P)g十丈节贡下;六j月+脚△X月甲H r6‘2(a’+ZJ)J“’尸u一一式中日为固体颗粒的导电率，。为电解质溶液的导电率，j为电解质溶液的电流密度，洲和尸分别为固体颗粒和电解质溶液的密度，产。为真空磁导率，△尤为固体颗粒与电解质溶液的磁化率之差，H为磁场强度，甲H为磁场梯度。上式表明，磁流体动力分选法是按物料的密度、导电率、磁化率进行综合分选的。强电解质溶液均可作为其分选介质，如NaOH、Nael、Hel和HZSO;溶液等。磁流体动力分选技术的研究始于190。年，用来分离贵金属和绝缘材料。此法在煤、错石、锡石、铁矿、锰矿、钾盐等的分选研究已取得成果。磁流体动力分选的设备简单，分选介质价格低廉，处理量大，有可能用于砂金或某些其他扩石的粗选，但与静力分选相比，其分选精度要低得多。 (郑龙熙)
