After the raw ore enters the ore processing plant through crushing, grinding and sorting operations, useful minerals in the ore are sorted into one or more concentrate products. Tailings are discharged in a slurry state. The yield of concentrates is relatively small, and the concentrate yield of non-ferrous metal concentrators is generally only 10% to 20%; the tailings amount is large, and the yield is generally 80% to 90%; even larger. If a small-scale concentrator that handles 100 tons per day, the amount of tailings discharged per day can reach 80-90 tons or more; if the ore grade is high and the concentrate yield is high, the amount of tailings is small. If a large amount of tailings is not properly handled, it will be very harmful. The tailings water discharged from the ore dressing plant often contains a large amount of pharmaceuticals and hazardous substances. The source is the flotation agent added during the beneficiation process and the metal elements in the ore. Commonly used are cyanide, xanthate, black drug, pine oil, copper ion, lead ion, zinc ion, and in some cases there may be arsenic, Phenol mercury and so on. When these harmful substances in tailings water fail to meet discharge standards, they are harmful to the human body, livestock, fish and farmland. Therefore, the tailings of the concentrator cannot be discharged arbitrarily. On the other hand, the concept of tailings is relative, and tailings contain a large amount of useful ingredients. At the current state of technology, useful components in the tailings of a tailings recycling machine can be redeveloped and utilized. Further scrutinization of the tailings will enable gold, silver, copper, iron and other useful minerals in the tailings to be fully recycled, which will greatly increase the economic benefits of the mine. Use tailings as a raw material for building materials to make cement, silicate tail sand bricks, tiles, aerated concrete, cast stone, refractories, glass, ceramic particles, concrete aggregates, glass-ceramics, slag-tile tiles, foam glass, and Foam materials not only reduce the waste of resources, but also create a higher value, in line with national policies such as energy-saving emission reduction, sustainable development, and resource reuse.
It can be seen that tailings cannot be discarded at will. Tailings disposal involves not only environmental protection and the rational use of resources, but also related to legal issues. Therefore, it is very important for the ore dressing plant to properly treat the tailings through the tailings recycling machine.
