Iron ore tailings are industrial solid wastes generated from mineral processing. The disposal of iron ore tailings leads to environmental threat and serious security because of their tiny particle size and large storage. In this paper, suspension magnetization roasting and magnetic separation technology were utilized to recover iron tailings. The results showed that iron concentrates …The invention provides a method for recycling iron ore concentrate from iron tailings and obtained iron ore concentrate. According to the method, minerals with different grain sizes in the iron tailings are processed in a staged mode, and after ball-milling and magnetic separating, the obtained concentrate is reunited and separated, and then the iron ore concentrate is obtained.

Refractory iron ore is often discarded as tailings. This causes a great waste of iron resources. In this paper, the flash roasting-magnetic separation process was designed by combining the magnetic separation process of magnetite and the process mineralogy of iron tailings. The flash suspension roasting effects with 3–4 s roasting time were evaluated …We design and manufacture a wide range of filter presses to dewater coal, mine tailings or minerals ore concentrates, like zinc or copper. +34 946 74 05 00 Home
