  任何一种非金属矿都有它特定的矿物组成和化学组成,自然界的单矿物很少,所以需要一个物理提纯的过程。重晶石物理提纯的主要方法有:手选、重选和磁选。其中手选主要是根据重晶石与伴生矿物的颜色、密度等差异,选出块状的重晶石。一些矿山,由于地质品味高、质量稳定,经手选 就可以满足外贸出口要求。如广西象州潘村矿,用手选法选富矿,粒度为15-30mm,BaSO4含量可大于95%。该方法简单易行,无需设备,但生产率 低,资源浪费大。重选是根据重晶石与伴生矿物的密度差别,把原矿经洗矿筛分、破碎、分级脱泥、跳汰、摇床等工艺,可获得品味大于88%的产品。重晶石嵌布 粒度大于2mm,通常用重介质分选、跳汰分选进行选别,重介质分选的最大粒度为 50mm,湿式、干式跳汰分选的最大粒度约为20mm;嵌布粒度小于2mm,可用摇床或螺旋分级机进行分选,精选前须用水力旋流器除去泥料以提高选别效 果。湖南衡南重晶石矿重选后的精矿含量达92%以上。该方法多用于残积型矿石。而磁选常用来除掉一些氧化铁类磁性矿物如菱铁矿,以作为要求含铁很低的钡基 药品的重晶石原料。其中干式强磁选机和湿式高梯度强磁选机在处理废金属矿物中尺寸较细和磁性弱的杂质时有不少成功应用的实例。
