Factors Affected to Acid Immersion Substance Removing from Coal Refuse

分析了影响煤矸石酸浸脱杂的几个主要因素，研究表明煤矸石矿物组成和性质、焙烧温度、酸浸条件等对煤矸石脱杂效果均有影响，特别是低温焙烧能显著提高杂质的活性，为煤矸石酸浸脱杂实现资源化提供了基础。

Abstract This paper analyzed main factors affected to acid immersion substance removing from coal refuse. A study shown that the property of the coal refuse mineral, baking temperature, acid immersion conditions all affected to the results of the substance removing from coal refuse. Specially, a low temperature baking can obviously increase activity of the substance which can be a base for resources of coal refuse after acid immersion substance removing.
