摘要
本文在分析煤矸石及其粉煤灰综合利用现状的基础上指出,以其为原料冶炼铝硅铁合金,不但可以充分利用其中能源和有价金属,而且还具有原料活性较强、容易还原、来源广泛和价格低廉等优点。此工艺具有显著的社会效益和经济效益。
On the basis of analysizing the present status of comprehensive utilization in coal waste and flyash,this paper points out that the coal waste and flyash used for manufacturing Si-Al-Fe alloy can utilize the energy resource and valuable metals completely,In addition these materials have the advantage of more activity,easy to reduce,extensive source and low in price.So this process is provided with significant economic and social profit.
