■The discharge of tailings is changed from dam-building to dump discharge, which cancels tailings pond and storage water, avoids the occurrence of accidents such as dam failure, flooding and dam collapse, and improves safety.
■High economy, reduce investment cost, save land acquisition cost, shorten construction period, low maintenance and operation cost
■To achieve zero discharge of waste water, save a lot of water resources for the society and save a lot of money for enterprises.
■Technical solution for tailings dry heap treatment, which can not only cofferdam to build fields and plant trees, but also backfill mine pits and subsidence areas, so as to achieve a double harvest of resource development and environmental protection.
■Simple management, easy operation, wide application, suitable for concentrated dry discharge of tailings of various particle sizes and concentrations.
◆Example of application equipment
■High-efficiency concentration cyclone ------ the core of tailings dry discharge system
The combination of high-efficiency concentration cyclone, thickener and dehydration screen can efficiently complete the concentration and dehydration process. After the concentration and dehydration of the cyclone, the increase of the underflow concentration creates good conditions for the dewatering screen operation, which can greatly increase the dewatering screen production capacity, and the reduction of the overflow concentration can effectively reduce the load of the thickener. With unique structural design, it is widely used in various concentrators. In iron ore, even if the ore feeding concentration is about 8%, the underflow concentration can still be maintained above 70%, and the yield is above 75%.
