Correct tailings treatment can effectively mitigate environmental pollution

With the continuous development of the mining industry, the number of metal tailings more and more, has reached more than five billion tons. Choosing the right approach is compulsory for each tailings Concentrator. Chinas existing tailings in more than four million, and the annual number of metal tailings at a rate of 600 million tons are in increments. Tailings so much, not only take up a lot of forest, farmland, causing great waste of land resources, and can easily cause environmental pollution. Therefore, as a concentrator, tailings disposal should choose the right way, in order to effectively mitigate environmental pollution reduce waste of land resources.



At present, China tailings handling most of the traditional hydraulic conveyance law, in the form of slurry, with water and sand tailings in all transported to and stored in the state of the swamp. Individual Concentrator some remote areas and even directly to the tailings discharge into the natural venue. Therefore, the comprehensive utilization of tailings is very low, only about 7%. Whether tailings in the tailings discharge or natural sites in the surrounding environment are causing a serious impact, mainly in: pulp water often contains toxic heavy metal ions as well as flotation reagent residues, and its surrounding areas for mining pollution and ecological destruction, its impact will be long-lasting; tailings in corrosion, or some may migrate into the tailings chemical element migration will cause serious pollution of the atmosphere and soil, leading to land degradation. Currently, the direct result of contaminated tailings area already caused hundreds of acres, and tailings dam height with a large pile of tailings increases, increasing hidden dangers. It is estimated that the annual economic loss due to pollution caused by solid waste at 30 billion yuan, of which each year to spend 10 to 15 billion yuan for the transport of tailings, 15 to 25 billion yuan for the maintenance of the tailings....
