| Abstract: | 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% |
