Separation of Rare Earth Elements from Monazite Via Sulfidationlly tedious. Conventional rare earth processing consists of a sequence of physical beneficiation, hydrometallurgical, and metallothermic or electrolytic processes to produce pure metals and alloys. Environmental impacts are concentrated in impurities management and material separation. Recently, sul

Recycling of Rare Earth Elements (REEs) from Scrap Nd-Fe-B Magnetsnerated, which are promising alternative resource for rare earth elements (REEs). Recycling of scrap Nd-Fe-B magnets will mitigate the demand supply gap of REEs. Thus, the present paper reports development of feasible hydrometallurgical flow sheet to recover REEs from Nd-Fe-B magnets. The process co

An Innovative Hydrometallurgical Process for Recovery of Critical and Rare Metals from Copper Anode mponents are precipitated to the bottom of electrolytic cells in the tankhouse or cellhouse. These settled insoluble components are called anode slimes. They contain copper, tellurium, selenium, bismuth, silver, gold, and traces of platinum group metals, such as platinum and palladium. Traditionally

Recovery and Enrichment of Platinum Group Metals from Spent Automotive Catalysts by Pyrometallurgy:reserves, large consumption, and high external dependence of PGMs are common problems nowadays. Therefore, the recycling of catalysts which contain PGMs has become an important method to alleviate the shortage of resources. This paper mainly introduces the pyrometallurgical recovery and enrichment

Eutectic Freeze Crystallization for Recovery of Cobalt Sulfate in the Recycling of Li-Ion Batteriesas been investigated. The cobalt sulfate salt was obtained by eutectic freeze crystallization (EFC) from a synthetic acidic cobalt strip liquor after solvent extraction. The ternary phase diagram of CoSO.–H.SO.–H.O was first established by the mixed-solvent electrolyte (MSE) model to predict and rev

Recovery of Copper Metal from Discarded Printed Circuit Boards (PCBs) by Hydrometallurgical and Elecuit boards (PCBs) to recover metals. Therefore, the present paper is focused on the recovery of copper (Cu) from waste PCBs using mechanical pre-treatment followed by hydrometallurgical processing. Initially, depopulated PCBs were pre-treated to get enrich copper in metallic concentrate. Further, ex
