Antimony is a chemical element with diverse uses that falls into the range of critical raw material. Although it appears in nature as stibnite, mining this mineralogical species rare or uncommon, and basically recovered secondary material processing various elements (such gold copper). Another source for recovery recycling Sb-bearing wastes such batteries alloys. Once dissolved order to recover from different leachates, adsorption processes are ones seem have, at least scientific community, highest acceptance. This work reviews most recent advances (in 2024) antimony sources using not only but also other technologies practical interest.

Demand and prices for antimony have increased over the last few years. Recycling supplied 15% of domestic consumption in US, while remaining 85% was imported. Hydrometallurgical processes long used alkaline sulfide systems hydrochloric acid, closing doors on new approaches. Bromine compounds been recently to recover PGMs REEs successfully; thus, leaching with bromine is theoretically feasible. This research conducted develop a viable technology hydrobromic acid between 50 °C 70 as reagent dross through single- two-stage using design experiment (DoE) adding sustainability current industrial minimizing waste products recycling processes. The preliminary results showed that bromine, specifically can be dissolution. By decreasing lead content solids increasing concentration, temperature, reaction time, from 20% 50%. findings, coupled regeneration, implemented an alternative other reagents plants.
