Procedures for the recovery of titanium contained in industrial residues in sulphate form and, where applicable, of other recoverable sulphates

摘要

Process for extracting recoverable elements contained in a residue containing titanium in the sulphate state, and which may contain sulfates of other elements, characterized in that the solid starting material is suspended in an aqueous liquid, because kaolin is added and then because the suspension thus obtained is heated between 80 and 160% c for a period of time from half an hour to 6 hours, after which the residual solution whose elements are recoverable and the precipitate containing the recoverable elements are separated. *** view image (Machine-translation by Google Translate, not legally binding)
