METHOD FOR THE DESILIFICATION OF AQUEOUS INORGANIC SOLUTIONS

摘要

Proposed is a method for the desilification of aqueous inorganic solutions, in particular pickling solutions, and a method of producing iron oxide with a reduced silicic acid content. The aqueous inorganic solution to be processed is fed to a cross-flow filter and passed through the filter at a temperature of 60-90 DEG C. In order to produce oxide, the filtrate is then converted to the appropriate oxide by spray roasting.
