A Study for Leaching Synthetic Scheelite in H2SO4 And H2O2 Solution: An Investigation and Optimization
DownloadFall 2023
Canada's 2021 Critical Minerals Strategy underscores the prominence of tungsten as a rare and critical element. Today, tungsten production relies on scheelite, categorized as a secondary resource due to its complex ore composition and lower-grade nature. This phenomenon stems from the depletion...

Coupled effects on the transport and deposition of biocolloidal particles in saturated porous media
DownloadSpring 2016
The transport and deposition of biocolloidal particles in porous media is a crucial phenomenon in understanding environmental challenges from pathogen contamination to bioremediation of soil and water. The fate and transport of biocolloidal particles in porous media is influenced by many factors...
