引言含锡低于30%的氧化锡原料,在还原为金属以前,一般都需要提高品位。虽然在精矿中有价值的元素的分配是低的,对适当的原料仍使用物理方法或浮选法。当矿石处理方法不适用时,自然生成的硫化物被用来进行硫化物烟
Introduction tin oxide containing less than 30% of the raw materials, before reduction to metal, generally need to improve the grade. Although the allocation of valuable elements in concentrates is low, physical or flotation methods are still used for the appropriate raw materials. Sulfur compounds, which are naturally occurring, are used to carry out sulfide fumes when ore processing methods are not applicable
