| Abstract: | A new method of deimpurity such as Fe2O3 from coal gangue in Huainan mines has been studied ,and an orthogonal experiment was carried out to inquire into the affection of leaching factors such as the roasting temperature,the leaching temperature ,the HCl concentration and the leaching time on deimpurity effect. The results have showed that the leaching activity of the impurity was improved by roasting at 350～400 ℃ and the impurity was leached from the roasted coal gangue by HCl. |
