按优先浮选锂辉石的流程获得的锂辉石精矿通常含有大量的铁。而按反浮选锂辉石的流程获得的锂辉石精矿是一例外,依据这一流程,在从矿物中浮出长石、石英、云母之后,再于氟化氢介质中利用树脂酸钠盐浮选出含铁的矿物。这样处理以后,槽内产品即是锂辉石精矿,共所含铁主要是以晶体形式的结合铁。这样的精矿在许多情况下能直接用于陶土 The spodumene concentrate obtained by preferential flotation of spodumene usually contains a large amount of iron. The spodumene by reverse flotation process obtained spodumene is an exception, according to this process, after the flotation of feldspar, quartz, mica from the mineral, and then in the hydrogen fluoride medium using sodium resinate Flotation of iron minerals. After this treatment, the tank product is spodumene concentrate, a total of iron is mainly in the form of iron binding. In many cases such concentrates can be used directly in clay
