长石(钠长石和微斜长石)作为各工业部门不可替代的原材料,其最有价值的组分是微斜长石,属钾长石类。为了获得微斜长石精矿,长石原料须加精选。研究和工作经验指出,由于钾模数小于1,因此,长石矿石最不易选;又由于矿物组分中各种矿物的理化特性相近,因此,在钠长石明显占优势的情况下,甚至借助浮选,实际上不可能有效地把微斜长石从钠长石中分离出来。
Feldspar (albite and micro plagioclase) is an irreplaceable raw material for various industrial sectors. The most valuable component of feldspar is plagioclase, a type of potassium feldspar. In order to obtain slightly plagioclase feldspar, feldspar raw material should be selected. Research and work experience indicate that feldspar ore is the most difficult to pick because the K modulus is less than 1, and because the physical and chemical properties of various minerals in the mineral composition are similar, so that in the case of obvious dominance of albite, With flotation, it is virtually impossible to effectively separate the plagioclase from albite.
