锡矿中经常有铁存在,氧化铁与锡石共生,二者以细粒晶体相互嵌布。当前选矿方法很难将二者较完全地分开,锡精矿中就难免有铁,有时含铁量不少。锡与铁共存于锡精矿中,还原熔烁时二者也在一起,自然要相互影响、相互制约。一般在锡精矿熔烁时为了降低渣含 Tin is often present in iron, iron oxide and cassiterite symbiosis, the two embedded in fine grain crystals. The current beneficiation method is difficult to completely separate the two, tin concentrate will inevitably have iron, and sometimes a lot of iron content. Tin and iron coexist in the tin concentrate, the reduction of the two are together, naturally affect each other, mutual restraint. In general, when the tin concentrate fusing to reduce slag content
