Economic Benefits: The tailings contain a large number of useful components (unrecoverable due to limitations in technology, equipment, conditions, etc.). For example: Yunnan Tin companies have tailings 28, 35 dam, reservoir tailings 150 million tons, an average of 0.15% tin, tin metal only in the loss of more than 20 tons; Daye Nonferrous Metals Company 5 copper mines, 1957--2500 million tons of tailings discharged in 1989, 63,000 tons of copper, gold 3373kg, silver 56175kg, 2,768,500 tons of iron; Henan province gold tailings discharged gold dressing plant The grade is 0.8-1.2g/T, and the annual loss of gold is more than 2.3 tons. There are also non-metallic minerals that can be recovered in the tailings. By using the patented equipment of this technology, the tailings resources can be further developed and utilized to effectively recover these useful minerals, thereby bringing huge economic benefits. Environmental Benefits: The iron sulfide contained in the tailings produces corrosive acidic salts and water under the long-term corrosion of nature's oxygen and water. The associated metal elements such as copper, lead , zinc and uranium are dissolved into harmful ions. The tail water discharge causes environmental pollution. The patented equipment of this technology can maximize the release of these valuable minerals from the tailings, thereby reducing the long-term effects of various metal elements in the tailings on the environment; using the patented equipment of this technology to re-select the tailings It is an important environmental protection measure to control the environment of tailings pollution. Social benefits: 1. After the mine is mined , the mine solid waste should not be sorted and reused under the conditions at that time, and it is often piled up in the tailings pond. There are more than 400 large-scale tailings ponds in China, and metal mines have more than 5 billion tons of tailings. At present, the total recovery rate of mineral resources in China is only about 50%. The annual discharge (by mining recovery rate) is about 60%-70%; the non-ferrous metal ore (including gold) is 40%-80%; non-metallic minerals. It is 20%-60%; causing a large amount of resources to be lost in the tailings. Due to the many useful components contained in the tailings, the patented equipment of this technology can further develop and recover the tailings resources, making it a new mineral resource. At the same time, it will also reduce the loss of national metals, and the most likely recovery of useful minerals. The positive direction of mine pollution environment turning waste into treasure 2, creating job opportunities for laid-off workers and stabilizing society. 3. Comprehensive utilization of tailings is a new social benefit growth point for the economic development of China's mining enterprises.
