An Efficient Process to Recover Iron from Bayer Red Mud
2022.6.15 We have investigated Bayer red mud with a TFe content of 26.86% collected from the Pingguo area of China, and have found that iron is the key metal affecting the extraction of valuable components such as Sc, Ti, and Ga. Based on this, an efficient process of roasting with calcium salt and magnetic separation has been proposed to extract iron from the Bayer

Once it gets solidified it forms a hard land mass which is very difficult to move, drainage into the water bodies causes gill suffocation in fishes and other marine lives.
