Method for solidifying and dry-stacking mill tailings without tailing reservoir

ActiveCN101912865APollution-free long-term storageAchieve stabilitySolid waste disposalEnvironmental qualityMaterials science
The invention relates to a method for solidifying and dry-stacking mill tailings without a tailing reservoir, comprising the following steps of: firstly, concentration of tailings: introducing the mill tailings into a concentration basin and adding a coagulant to concentrate the tailings to the state of the mass concentration greater than 50%; secondly, solidification of the tailings: guiding the concentrated tailings into a solidifying stirrer, mixing with a solidifying agent and stirring; thirdly, primary curing of the solidified tailings: stacking the solidified tailings for 24 hours to carrying out primary curing; and fourthly, dry stacking of the solidified tailings: filling the primarily cured solidified tailings in a stacking field by using a layered and subdivided filling method, and compacting after each-layer filling. The method has the advantages that the liquid tailings are solidified into solidified bodies having certain strength and meeting the requirement of environmental quality and can be directly stacked in the stacking field without establishing the tailing reservoir, thereby thoroughly eliminating the wet stacking stability and environmental pollution risks of the tailings in the tailing reservoir, saving the land occupied area of the stacking field and having remarkable economic, social and environmental benefits.
