Verfahren zur Verarbeitung von metallchloridhaltigen Abfällen.

摘要

A process of treating metal chloride wastes produced by chlorination of titanium ore comprises the steps of: (a) leaching said metal chloride wastes in a hydrochloric acid (HCl)-containing solution to obtain a solution containing solids and dissolved metals, (b) separating said dissolved metals from said solids present in the solution obtained in step (a) to obtain a liquid and a residue, (c) selectively precipitating the metals as their hydroxides by adding a neutralizing agent to the liquid obtained in step (b), (d) separating the precipitate of metal hydroxides obtained in step (c) from the liquid to obtain a residue, and (e) dewatering the residue obtained in step (d). c
