Water-saving tailing discharge method
The invention belongs to the field of metallurgical mines, and particularly relates to a water-saving tailing discharge method. A place is selected according to the tailing pond address selection principle. A tailing pond, a primary dam, a floodwater drainage system, a seepage drainage system, a tailing conveying system, a tailing classification and condensation system, a water return system and other matched facilities are reasonably arranged according to terrain and geological conditions. The tailing conveying system comprises a section from a dressing plant to a hydrocyclone, a section from the hydrocyclone to a thickener, and a section form the underflow of the thickener to the tailing pond. Pumping or self-flowing conveying can be adopted for the conveying process of each section. The tailing classification and concentration involves the steps that ore pulp coming from the dressing plant is classified through the hydrocyclone; and overflow tailing ore pulp of the hydrocyclone is concentrated through the thickener. The water return system comprises a thickener overflow water return system and a tailing pond water return system. Return water can be conveyed to the mineral processing process to be recycled in a pumping or self-flowing conveying manner. The tailing pond formed through the method is good in anti-seismic property, high in return water utilization rate, low in dam body seepage line, large in anti-slide buckling safety factor, wide in application range and low in operation and management expense.
