黑龙江鸡西煤矸石中镁、钙、铁、钛的测定

煤矸石是采煤过程和洗煤过程中排放的固体废物.是一种在成煤过程以及煤层开采过程中伴生的一种含碳量较低、比煤坚硬的黑灰色岩,是碳质、泥质和砂质页岩的混合物.相对于煤岩来说它们的发热值偏低.主要成分是氧化铝、氧化硅,另外还含有数量不等的氧化铁、氧化钙、氧化镁、硫等和微量稀有元素(钛、镓、钒、钴).对黑龙江鸡西煤矿的煤矸石进行了氧化镁,氧化钙,氧化铁,氧化钛成分的分析测量,同时对黑龙江省煤矸石的综合利用提出了参考性建议.

Determination of magnesium,calcium,hard,titanium In Heilongjiang Jixi gangue

Coal gangue is the solid waste which comes from the coal mining and coal washing process.It is a kind of dark gray rock which forms during coal-forming process and coal mining process.Its carbon content is low and it is harder than coal.It is a mixture of carbon,clay and sandy shale.Compared with the coal petrology,coal gangue's calorific value is lower.Coal gangue's main ingredients are alumina and monox,besides,it also contains varying amounts of ferric oxide,calcium oxide,magnesia,sulfur and trace rare e...
