Recovery of aluminium and lithium from gypsum residue ...

2015-10-1  The Bayer process was used to separate aluminium from the gypsum residue. The gypsum residue was first digested by an alkali (NaOH) solution. The digestions were conducted in an autoclave (KCFD, Songlin Chemical Equipment Co., Ltd) with a pressure range of 0.5 MPa to 10 MPa. After filtration, the gypsum was separated from the digestion solution.
