摘要：

One of the main tailings of the aluminium industry is red mud, which is a kind of hydrous silt-muddy, highly alkaline solid waste produced by physical and chemical treatments of bauxite in alumina (Al2O3) production. As red mud is seriously harmful to the ecological environment, the safety of its storage has become an environmental problem of much concern in China and abroad. Using the disposal of the waste by an aluminium factory in Shanxi province of China as an example, the authors have studied the physical, chemical and mineral properties, the undesirable engineering properties of the red mud and their formation mechanisms, and have presented the principles and methods concerning storing, reinforcing and utilization of the waste in this paper. Also it was hoped to show the important role of engineering geology in solving this environmental problem.
