Hot water extraction of bitumen from Alberta oil sands generates large quantities of tailings sluny. The fine grained sludge component of this waste is the most troublesome because of its stability and poor compaction potential. Dispersed bitumen, and organic matter that is insoluble in common solvents (IOM), are associated with the fines contained in these. clay slimes. This organic matter is ...

Lithiophilic hosts are confirmed to effectively enhance the electrochemical stability of lithium (Li) anodes, thereby guaranteeing safe, practical application Li metal as anode in rechargeable Li-ion batteries. This study reveals a lithiophilic three-dimensional copper current collector (Ag@CF). Silver (Ag) nanoparticles were anchored on surface skeleton foam (CF) via facile displacement reacti...

Lizardite slime coating is one of significant factors in the deterioration floatability sulphide minerals. In this study, a nanoparticle cationic polystyrene-co-poly(n-butylacrylate)(PS-PBNH) collector was introduced to eliminate negative impact lizardite slimes pyrite flotation. Microflotation results demonstrated that slims did not affect recovery presence PS-PBNH. Good flotation separation f...

This paper describes the fabrication of transparent electrodes based on grids of copper microwires using a non-photolithographic process. The process--"abrasion lithography"--takes two forms. In the first implementation (Method I), a water-soluble commodity polymer film is abraded with a sharp tool, coated with a conductive film, and developed by immersion in water. Water dissolves the polymer ...
