矿物极化
mineral polarization

  kuangwuj一huo矿物极化(mineral polarization)电选过程中昨导体矿物受外电场作用后,矿物中分子正负电荷的重心错开,形成电偶极矩,最终在矿物两端产生正、负束缚电荷而出现两个极的带电现象。微细粒的高梯度介电分选就是运用这种矿物带电方法来实现分选的。 绝大部分非金属矿物均由无极分子所组成。一旦受到外电场作用后,则分子的正、负电荷中心不再重合而产生偏移,形成一个电偶极子,偶极矩的方向沿外加电场方向排列,此电偶极矩称感生极矩。由于每一分子形成了电偶极子,各偶极子均沿外电场排列成链条状,相邻偶极子的正、负电荷互相接近,内部各处是中性,但在矿物的两端面则出现正、负电荷,也即产生极化。这种电荷与导体中的自由电荷不同,不能离开介质而转移到其他带电体上,也不能在介电体内自由移动,故称为束缚电荷。极化及其束缚电荷分布状况如图所示。在高梯度电选时,介电体在电场中极化,极化的介电体再吸引或排斥矿物,从而达到分选的目的。 。-一厂丁一t二二丁一代习~+ 一一-,~一‘一十~+ b 极化及其束缚电荷分布状况 a电偶极子;为一两端面出现的正负束缚电荷 (刘永之)
