Abstract

The invention provides a low-energy-consumption environmentally-friendly magnetized calcination tailing cooling processing system which comprises a closed tailing cooling tank. The cooling processing system is characterized in that the closed tailing cooling tank is vertically arranged, the upper portion of the closed tailing cooling tank is provided with a material inlet, the lower portion of the closed tailing cooling tank is provided with a material outlet, and the tank is internally and vertically provided with a water circulating spiral conveying pipe; the water circulating spiral conveying pipe comprises a water circulating spiral cavity and a material spiral sliding channel, the material spiral sliding channel is located on the upper surface of the water circulating spiral cavity and is spiral downwards together with the water circulating spiral conveying pipe; and the water circulating spiral cavity comprises a water inlet and a water outlet.

Description

technical field [0001] The invention relates to a low energy consumption and environment-friendly cooling treatment system for magnetized roasting tailings. Background technique [0002] Tailings are usually one of the largest solid wastes produced in mineral processing. Most of the tailings enter the tailings pond or fill, and are also the largest source of pollution in the mineral processing industry. Billions of tons of tailings are discharged in the tailings in China every year. In the tailings produced by metal ore dressing, most of the iron oxide and other metal elements are not effectively recycled and directly discharged into the tailings pool or filling; and if the development and utilization of a large amount of long-term accumulation Solid waste tailings can not only "turn waste into treasure", but also effectively alleviate the pressure on resources and the environment, and can release a large amount of land resources occupied by tailings. Most of the tailings in...
