Treatment method for recycling lepidolite leaching residues containing iron
The invention discloses a treatment method for recycling iron-containing lepidolite leaching residues, which is characterized by comprising the following steps: 1) mixing the iron-containing lepidolite leaching residues with sulfuric acid, leaching in a constant-temperature water bath, filtering to obtain filtrate A and filter residues A, and drying the filter residues A to obtain white filter residues A; (2) adding ammonia water into the filtrate A, heating and stirring in a constant-temperature water bath, and filtering to obtain filtrate B and filter residues B; and 3) continuing to add ammonia water into the filtrate B, stirring and leaching, and then concentrating, filtering and drying to obtain the nitrogen-potassium fertilizer. 4) adding hydrochloric acid into the filter residue B, heating and stirring, filtering to obtain filtrate C and filter residue C, and washing and drying the filter residue C to obtain white carbon black; and 5) concentrating and drying the filtrate C to obtain aluminum trichloride hexahydrate. The method has the advantage that the ceramic raw material, the nitrogen-potassium fertilizer, the white carbon black and the aluminum trichloride hexahydrate can be prepared at the same time.
本发明公开了一种含铁锂云母浸出渣回收利用的处理方法，特点是包括以下步骤1)将含铁的锂云母浸出渣与硫酸混合后在恒温水浴中浸出后，过滤得滤液A和滤渣A，滤渣A烘干得白色的滤渣A；2)在滤液A中加入氨水，恒温水浴加热搅拌后过滤获得滤液B和滤渣B；3)在滤液B中继续加入氨水搅拌浸出，然后浓缩、过滤、干燥后获得氮钾肥；4)在滤渣B中加入盐酸加热搅拌，过滤后得滤液C和滤渣C，滤渣C经过洗涤、干燥后得到白炭黑；5)滤液C浓缩、干燥后获得六水合三氯化铝，优点是能同时制备陶瓷原料、氮钾肥、白炭黑和六水合三氯化铝。
