The paper presents the results of investigation of the process of leaching of scandium from chloride wastes generated in titanium production to optimize the parameters of extraction into solution. The effects of key factors, including solid-to-liquid ratio (S:L), hydrochloric acid (HCl) concentration, process duration, stirring speed and the influence of temperature on the degree of scandium extraction into solution were studied. Experimental results indicate that optimal conditions for maximum extraction are: S:L...

The processing of titanium-zirconium concentrates with high chromium content presents a significant challenge due to the inhibitory effect of chromium on industrial applications. This study investigates the composition of titanium-containing concentrate from the Obukhovskoye deposit using X-ray diffraction (XRD), X-ray fluorescence (XRF), and thermogravimetric analysis. The findings indicate that chromium is uniformly distributed in both magnetic and non-magnetic fractions, complicating its selective removal by co...
