Some Recent Advances on Germanium Recovery from Various Resources

Опубликована: Апрель 18, 2024

Though nowadays germanium do not reach the range of popularity than other metals, i.e. rare earth elements, its utility in target industries makes it also a strategic metal. can be find series raw materials, principal source for recovery is from secondary wastes zinc industry, and also, recycle germanium-bearing waste materials becoming interest. In this recovery, Hydrometallurgy performing key role to successful achievement goal. The present work reviews most recent applications (2023 2024 years) hydrometallurgical operations on different solid liquid sources.

Though nowadays germanium does not reach the range of popularity other metals, i.e., rare earth elements, its utility in target industries makes it a strategic metal. can be found series raw materials, principal source for recovery is from secondary wastes zinc industry; also, recyclability germanium-bearing waste materials becoming interest. In this and due to size because diffusion reaction are considered, hydrometallurgy performs key role achieving goal. The present work reviews most recent applications (2023 2024 years) hydrometallurgical operations on different solid liquid sources.

Recovery of Lesser-Known Strategic Metals: The Gallium and Germanium Cases

Processes, Год журнала: 2024, Номер 12(11), С. 2545 - 2545

Being not as popular other elements, such cobalt, lithium, and rare earth both gallium germanium have wide use in target developments/industries, thus making them valuable strategically critical metals. The principal sources for the recovery of metals are secondary wastes bauxite (gallium) or zinc (germanium) industries; also, their recycling from waste materials is necessary. characteristics these make hydrometallurgical operations widely useful recovering various containing them. present work reviews most recent applications (in 2024) applied to resources.

Crosslinked Polydiallyldimethylammonium Chloride Adsorbent for the Selective Separation of Rhenium Ions from Pregnant Leach Solutions

Materials, Год журнала: 2024, Номер 17(11), С. 2737 - 2737

The depletion of valuable mineral reserves has rendered effluents generated from mining and industrial processing activities a promising resource for the production precious elements. synthesis improvement new adsorbents to extract compounds wastes pregnant leach solutions, besides increasing wealth, can play significant role in reducing environmental concerns. In this work, low-cost adsorbent selective extraction rhenium (perrhenate ions, ReO4−) was synthesized by free-radical polymerization (FRP) diallyl dimethylammonium chloride monomer (quaternary amine) presence crosslinker. Various methods were employed characterize polymeric adsorbent. results revealed that designed had high surface area pores with nano-metric dimensions pore volume 6.4 × 10−3 cm3/g. Four environments—single, binary, multicomponent, real solutions—were applied evaluate adsorbent’s performance separation Re. Additionally, these environments used understand behavior molybdenum primary competitors perrhenate ions ion exchange process. competitive conditions, using variations qe,mix/qe, an antagonism phenomenon (qe,mix/qe < 1) occurred due inhibitory effect surface-adsorbed on binding ions. However, across all values Re higher than those other studied elements (Mo, Cu, Fe).
