This report investigates the effective separation of columbium, tantalum, titanium, and zirconium from titanium chlorination residues, addressing a critical need in metallurgy. The objective was to optimize extraction processes to recover these valuable metals from complex waste matrices. Utilizing a series of hydrolysis and precipitation experiments, a composite leach liquor was prepared by water leaching solid wastes. The study revealed that boiling the leach liquor led to partial precipitation, but complete separation was not achieved until heat and pressure hydrolysis were applied at temperatures ranging from 130° to 200° C. The results indicated that increasing the temperature to 130° to 150° C optimized the precipitation of these metals, significantly enhancing the overall recovery efficiency. Detailed analyses of raffinate and strips from a ten-stage extractor demonstrated effective separation while also providing insights into the interactions of various acid concentrations and extraction times. This comprehensive approach contributes to more sustainable metallurgical practices by improving metal recovery from industrial by-products.
