一种从回转窑水淬渣中回收铁的方法
摘要：
本发明涉及一种从回转窑水淬渣中回收铁的方法。将回转窑水淬渣球磨至300－400目占90％以上，在磁场强度0.1－0.2特斯拉下进行磁选，所选得的铁精矿品位在50－70％，硅小于8％，达到铁精矿的要求。尾矿含铁低于15％，可作为水泥工业的添加剂。本发明能解决回转窑水淬渣大量堆存，污染环境，有价金属流失的问题，起到综合回收利用资源和发展循环经济的作用。
摘要（英）：

The present invention relates to a method for recycling iron from rotary kiln water quenched slag. The rotary kiln water quenched slag is milled until the rotary kiln water quenched slag of 300 to 400 meshes takes more than 90 percent; magnetic separation is processed under the magnetic density of 0.1-0.2 tesla; the grade of obtained iron ore concentrate is between 50 percent and 70 percent, silicon is less than 8 percent, and the requirement of the iron ore concentrate is achieved. The iron content of a mine tailing is less than 15 percent, and the mine tailing can be used as the additive of cement industry. The method can solve the problems that the rotary kiln water quenched slag is stored at a mass and pollutes the environment, valuable metal loses, and the method takes effects of recycling and using resource comprehensively and developing circular economy.
