Scandium (Sc) is classified as a critical and strategic raw material due to its applications in the aerospace industry and in modern energy systems. As scandium rarely forms independent minerals, it accumulates in secondary streams. This article describes a conceptual process, which can be integrated into existing titanium processes, for the selective recovery of scandium from chloride-rich hydrolysis solutions from titanium d...

This article investigates the mineralogical characteristics and beneficiation potential of zircon and phosphate minerals in ilmenite-rich heavy mineral sand tailings from a Ukrainian deposit. Based on a comprehensive fractional class analysis, it is observed that a significant enrichment of zircon, monazite, and xenotime occurs in the fine fraction (

The REPTiS project ( R esponsible E xtraction and P rocessing of Ti tanium and Other Primary Raw Materials for S ourcing EU Industrial Value Chains and Strategic Sectors) addresses the urgent need for a secure and sustainable supply of titanium and other critical raw materials (CRMs) within the EU. Given the EU’s dependency on imports and the risks of supply chain disruptions, REPTiS focuses on the responsible extraction and p...

Summary Enrichment cultures capable of reductively dechlorinating 1,2,4‐trichlorodibenzo‐ p ‐dioxin (1,2,4‐TrCDD) were shown to dechlorinate 1,2,3‐trichlorobenzene (1,2,3‐TrCB) to 1,3‐dichlorobenzene. To test if this activity can be used to enrich for dioxin‐dechlorinating bacteria, a two‐liquid phase cultivation with 200 mM 1,2,3‐TrCB dissolved in hexadecane was established. During the dechlorination of 1,2,3‐TrCB, the number...
