摘要
某煤系高岭岩系列煤矸石经干馏脱油气、脱碳、强磁选、浸出、氯化焙烧除铁、钛及增白工艺 ,制取优质高岭土取得了较理想的结果 ,且试验的重现性好、指标稳定 ,其铁、钛含量可相应降低到 1%以下 ,产品白度大于 90度。
The fine kaolin production is obtained using the coal mine gangue by the following process: carbonization to pull off the oil and the gas from the gangue, roasting to decarburization, strong magnetic separation, leaching, chlorination roasting to move the Iron and Titanium and whitening The impurity contents of Iron and Titanium are lower than 1 percent, the white degree of the product is more than 90%
