The formation and transformation of schwertmannite during the preparation of ferric hydroxide with acid leaching filtrate of tailings

During the process,precipitates of Fe3+(schwertmannite) and Mg(OH)2 were separated from this leaching filtrate according to different precipitation pH values of the metallic ions,and the precipitation mixtures of Al,Co,Ni and Cu can be obtained simultaneously.
