Method and equipment for resource utilization and innocent treatment of manganese slag
The invention discloses a method and equipment for resource utilization and harmless treatment of manganese slag, and the method comprises the following steps: washing the manganese slag by using a water washing method to separate ammonium sulfate from manganese sulfate, electrolyzing the manganese sulfate to obtain electrolytic manganese, and carrying out harmless treatment on waste slag obtained by washing and filter pressing with slag washing water, the divalent manganese and ammonium sulfate in the manganese slag are recycled, the waste slag is subjected to harmless treatment, the waste slag subjected to harmless treatment can be used for producing environment-friendly bricks or used as a cement mixture, and recycling and economic circulation of resources are achieved. According to the method, the production cost is low, the recovery rate of the separated and recovered soluble manganese and ammonium sulfate can reach 80% or above, the treated manganese slag reaches the national building material quality standard, the method is environmentally friendly and safe, the comprehensive utilization value of the manganese slag is increased, and sustainable development is achieved.
本发明公开了一种锰渣的资源利用及无害化处理的方法与设备，该方法包括利用水洗法对锰渣进行洗涤将硫酸铵与硫酸锰分离出来，再将硫酸锰电解得到电解锰，后将经过洗渣水洗涤压滤得到的废渣进行无害化处理，完成锰渣中二价锰和硫酸铵的回收以及废渣的无害化处理，无害化处理过后的废渣可用于生产环保砖或作为水泥混合料使用，实现资源的回收利用、经济循环。本发明所述方法生产成本低，且分离回收得到的可溶锰与硫酸铵其回收率能够达到80%以上，处理过后的锰渣达到国家建材质量标准，本发明方法环保安全、提高锰渣的综合利用价值，实现了可持续发展。
