A STUDY ON SINTERING PROCESS OPTIMIZATION OF ALUMINA ATTRACTION FROM FLY ASH

摘要

Fly ash is an industrial by-product generated during thecombustion of coal in power plant. In Inner-Mongolia, thecontent of Al2O3 in fly ash can reach as high as 50wt%. In thispaper, alumina was attracted through soda-sintering process, thework was based on six sigma approach in order to optimize thesintering variables, analysis of various critical processparameters and the interaction among them was carried out withresponse surface method- logy (RSM), the optimized parametersobtained using RSM were then tested to meet the predictedparameters.
