Dry tailings discharge is a new tailings disposal of the new technology in recent years, the gradual rise of China refers to the output through beneficiation process tailings slurry after multi-level concentration, then dehydration, such as efficient dewatering shaker device processing, the formation of small aqueous easy to use site precipitation curing and stockpiling of slag, slag can be transported to fixed locations stockpiling dry. Tailings dry tailings discharge reasons, one of the products that separate beneficiation operations, its lowest content of useful components in the current technical and economic conditions, not further sorting ore, tailings has become final. Component content does not represent the value of the lowest minimum. Tailings are experts generally believe that explore the potential large secondary use of high importance treasures. Let us put aside the interests of the value it can bring not see the need for large accumulation of tailings has a large tailings would cause great environmental pollution, but also likely to cause the tailing dam accident, a security risk . So dry tailings discharge, without delay! Tailings dry platoon advantage a row using dry tailings fill goaf technology to solve the traditional tailings discharge tailings, environmental pollution, there are security risks and take up a lot of land Question 2 after the tailings dewatering, dry emissions, not only can save construction costs of traditional and conventional tailings maintenance costs, you can also make full use of artesian backwater, but also saves floor space, eliminate tailings security risks. Also in mine production process, eliminate safety hazards mined-out area, saving investment in safety, to be reclaimed and restored landscapes, environmental governance save money conducive geological environment, to achieve a waste substitution. 3 dry tailings discharge process using the equipment, technology, innovative technology for the comprehensive management of mining tailings pile and empty areas opened up a new way. 4 small investment, big benefit. Calculated using dry tailings discharge after filling the goaf process, saving fixed assets investment, money-saving safety management, environmental management of funds, energy conservation, and tailings maintenance costs. Dry tailings discharge cyclone and the way a combination of tailings dewatering shaker after enrichment by cyclone underflow into the high frequency vibration sieve dehydration dehydration, can make the water content less than 16% of tailings, tailings reach dry drained heap object. In this way the effect is good, low investment, high efficiency, is currently on the market is the most economical and practical way. 2 direct use of concentrated mechanical filter, this approach is relatively large initial investment, smaller scope, sometimes can not meet the production efficiency or the degree of dehydration.
