根据焙烧反应原理,奥地利铅矿联合公司(BBU)的旋转膛式炉法也有可能用于小型的炼铅厂而经济地熔炼铅,但是,这种方法的先决条件是硫化铅精矿的品位要在70%以上。BBU法用于处理蓄电池废铅板也能取得很好的效果。
According to the roasting reaction principle, the rotary hearth furnace method of Austrian Lead Briquette Union (BBU) is also likely to be used for smelting lead economically in small smelters, but the prerequisite for this method is the grade of lead sulphide concentrate Above 70%. BBU method for the battery lead-acid board can also achieve good results.
