The results showed that: the finalconcentrate did not be improved after crude concentrate was screened by magnetic screening;
结果表明:再磨后的一段精矿经磁筛精选,最终精矿铁品位未能提高;

The floatation tungsten concentrate is treated by acid pickling to remove phosphonium and carbonate, and its finalconcentrate is 70.
浮选钨精矿经过酸浸除磷、碳酸盐后,获得混合钨精矿品位为70。
