Abstract
The invention relates to a method for preparing ceramsite from waste manganese ore slag. The method comprises the following steps that the waste manganese ore slag, clay and coal powder are mixed, dried and ground to obtain a preliminary mixture; bentonite and water are added into the preliminary mixture, mixing integration is conducted for a period of time, and a final mixture is obtained; the final mixture is pelletized to obtain wet pellets; the wet pellets are dried; the dried pellets are roasted to obtain the ceramsite. According to the method, the process is simple, operation is easy and convenient, the waste manganese ore slag is utilized, the problem that the waste manganese ore slag pollutes the environment is solved, waste materials are changed into things of value, the high-strength ceramsite is prepared by comprehensively utilizing the manganese ore slag resource, and the performance is greatly improved. The method is mature in technology, free of secondary pollution, low in cost and suitable for industrialized production.
