With the rapid increase of new energy industry, the shortage of critical metals for new energy
industry, such as Ni, Co, V, and Pt, has received global attention. The hazardous spent …

As an important secondary resource with abundant platinum group metals (PGMs), spent
catalysts demand recycling for both economic and environmental benefits. This article …

To ensure the supply of raw materials for products of extreme importance in strategic
sectors, the recovery of critical metals from secondary sources becomes increasingly urgent …

In this study, selective extraction and recovery of Au (III) from a tertiary metal solution
containing Au (III), Pt (IV), and Pd (II) were investigated using ionic liquid Aliquat-336. The …

Discharge of waste contaminated with heavy metals and related elements is known to have
an adverse effect on the environment and solving this problem has for long been presented …

Platinum group metals (PGMs) are widely applied in the field of catalysts due to their
excellent catalyst activity and high-temperature stability. The rapid generation of the waste …

Heavy metal contamination has become a worldwide environmental concern due to its
toxicity, non-degradability and food-chain bioaccumulation. Conventional physical and …

Abstract The recovery of Pd, Pt, Rh and Ru from an automotive catalyst and from an alumina-
supported Ru catalyst was studied. Microwave-assisted leaching of Pd, Pt, Rh and Ru was …

Platinum is one of the platinum group metals that are found in nature in small quantities
along with other metals in various ores. In order to meet its increasing demand, it is …

Effective and energy-efficient separation of precious and rare metals is very important for a
variety of advanced technologies. Liquid–liquid extraction (LLE) is a relatively less energy …
