The market for lithium-ion batteries (LIB) is experiencing substantial growth, what owed to electromobility and the growing demand cordless devices. Securing raw material base LIB mandatory achieve objectives of EU commission's Green Deal. This implies not only sufficient access lithium but also accompanying metals, above all Co, Ni, Mn. After preceding recovery Li2CO3 by COOL-Process subsequen...

The separation of manganese from cobalt sulfate solutions is crucial in the field spent lithium-ion battery recycling. A membrane-based microreactor used to reveal required mass transfer characteristics as diffusion and chemical reaction. dependence di-(2-ethylhexyl)phosphoric acid (D2EHPA) concentration, pH, metal ion concentration on extraction efficiency are investigated. back-reaction term ...

O Brasil a pesar de ter uma das maiores reservas dos Elementos Terras-Raras (ETRs) produz muito pouco deles. Um desafios para produzir os ETRs é dominar etapa separação e purificação A técnica extração por solventes o método mais amplamente utilizado na indústria separar purificar ETRs. objetivo deste estudo foi avaliar efeito que, sobre do Gd mistura ETRs, tem as variáveis: tipo extratante, co...
