PILING METHOD OF BUILDING DAMS WITH RED MUD FROM SINTERING PROCESS AND PILING RED MUD FROM BAYER PROCESS

摘要

In a method of piling red mud, red mud from sintering process is conveyed to the red mud piling yard which is divided into three or more subdivisions, and is used for building a dam in a subdivision I at first. Upon the dam in the subdivision I reaches the desired altitude, the red mud from sintering process is transferred to a subdivision II and is used for building a dam therein, while red mud from Bayer process is piled in the subdivision I. Upon the dam in the subdivision II reaches the desired altitude, the red mud from sintering process is transferred to a subdivision III to build a dam therein, while the red mud piled in the subdivision I is under drying, and the red mud from Bayer process is piled in the subdivision II. Such that, the method of piling red mud with a circulation of building a dam using red mud from sintering process, piling red mud from Bayer process, and drying red mud by turns is established.
