A Method of Fault Monitoring and Diagnosis for the Thickener in Hydrometallurgy
IEEE Access, 2019 Hydrometallurgy is a metallurgical method for processing complex ores and low-grade ores while reducing environmental pollution. The density of the thickening process in hydrometallurgical production is rather poor, and there are many interference ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A simplified direct carbothermic reduction (SDCR) process is developed for efficient recycling of spent LiCoO2 cathodes. The SDCR method employs carbon conductive agents and organic binders embedded in the electrode as internal reducing agents, while the confined pores of calendered electrodes promote the retention of in situ generated reduction gases.

Heap Leaching: Modelling and Forecasting Using CFD Technology [PDF]
, 2018 Heap leach operations typically employ some form of modelling and forecasting tools to predict cash flow margins and project viability. However, these vary from simple spreadsheets to phenomenological models, with more complex models not commonly ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This review addresses the nucleation mechanism and the thermodynamic and kinetic reaction processes of co‐precipitation. The comprehensive effects of key parameters on precursor physicochemical properties are also systematically interpreted. Notably, precursor characterization and physicochemical properties, including impurity levels and tolerance ...

MetalMat, EarlyView.Hydrometallurgical flowsheet to extract lithium from spodumene by combining leaching with maleic acid and solvent extraction with Cyanex 936P. ABSTRACT This paper explores a novel approach to lithium recovery from spodumene, a lithium‐bearing mineral. Instead of traditional sulfuric acid leaching, organic acids—specifically maleic acid—are investigated
