摘要
结合平朔矿区粉煤灰的特性,提出从粉煤灰中提取白炭黑和氧化铝的工业利用新途径,采用低温常压碱浸法提取白炭黑,采用碱石灰烧结法提取氧化铝,生产后的废渣可用作水泥生产原料;要想更好地发展粉煤灰综合利用项目,建议国家从科研开发资金及税收等方面给予大力扶持。
In connection with the characteristics of fly-ash produced in Pingshuo mine region,a new way of its industrial utilization proposed,in which white carbon-black extracted by alkaline leaching at ordinary pressure,aluminum oxide produced by sintering with alkaline lime,and the residue used as raw material for cement production;for better development of comprehensive utilization of fly-ash,energetic support by state regarding R & D fund and taxation suggested.
