目前主要是以重选方法实现黄绿石一锆石矿石和砂矿的选矿。用联合法(静电选和电磁选、重选、浮选和粒浮)进行黄绿石一锆石混合精矿的分离和精选它们成为合格精矿。黄绿石一锆石矿石的复杂的物质组成、主要矿物的比重接近、矿物的脆性和细粒浸染使得用重选法选别这类矿石的效果不大,甚至在某些情况下不能够选别。在这种情况下有价成分的主要损失是由于形成大量的矿泥(-0.074毫米)而产生的,实际上用重选法是不能从这种矿泥中回收这些有价成分的。因此在选别复合性难选黄绿石一锆石矿石时,浮选具有很大
The main method is to re-election method to achieve a yellow-greenstone a zircon ore and ore dressing. The separation and refinement of the pyrochlore-zircon composite concentrate by the combination method (electrostatic and electromagnetic separation, reselection, flotation and particle floatation) make them eligible. The complexity of the composition of the pyrochlore zircon ore, the proportion of the main minerals close to the friability of the minerals and fine grained make use of re-election method of sorting such ore is not effective, and even in some cases can not choose. In this case, the major loss of the valence component is due to the formation of a large amount of slime (-0.074 mm) which, in fact, can not be recovered from such slime by the re-election method. Therefore, in the selection of complex refractory a garnet a zircon ores, flotation has great
