Abstract

The invention relates to the metallurgical industry specifically to the acid treatment of red mud obtained in the process of producing alumina and can be used in technologies for recycling waste from alumina refinery holding ponds. The method for the acid treatment of red mud involves leaching using a leaching agent comprised of water soluble aliphatic carbonic acids having fewer than 3 carbon atoms per molecule filtering the solution and separating the recoverable end products. To ensure a high level of recovery of valuable components and the increased productivity of the process leaching is conducted with the addition of red mud in portions and with the control of pH values and when a target pH value of between 2.3 and 3.8 is reached no more red mud is added and once leaching is complete the solution is kept at a given leaching temperature for no less than one hour.
