Résumé Le vanadium est produit à partir de diverses sources. Ce métal est connu pour permettre des solutions aqueuses de spéciations complexes en fonction de la concentration du vanadium et du pH. En tenant compte de la méthode de lixiviation, des impuretés dans la solution mère de lixiviation et du produit de vanadium planifié, divers agents d’extraction et schémas de traitement peuvent être mis en oeuvre pour purifier la solution. Le présent article étudie la purification de la solution de lixiviation du vanadium au moyen d’extractants organophosphorés, solvants et aminés. L’étude cible la séparation du vanadium du fer, du molybdène et de l’uranium, lesquels sont souvent présents dans les ressources de vanadium telles que les minerais primaires, les cendres volantes et les catalyseurs usés.
Mots clés : Extractants organiques, extraction par solvant, purification du vanadium, ressources de vanadium

Sommaire: The toxicity of arsenic is well known and documented; however, the presence of arsenic in copper electrorefining anodes and electrolytes is critically necessary to produce high-quality cathode. Arsenic as well as antimony and bismuth concentrations vary relative to their concentration in the anode copper received from the smelter. The behaviour and benefits of arsenic in copper electrorefining and the detrimental effects of antimony and bismuth on cathode quality and tankhouse performance are...

Sommaire: In projects involving resource development and plant optimization, the use of in-mine geophysics can deliver considerable benefit. The value proposition lies in using very high resolution downhole measurements to model process-plant outcomes. The calibration procedure used to convert in-situ physical properties into process engineering parameters is illustrated using two iron ore projects. Data correction was related either to orebody structure or mineral formation. The deliverable from this...

Sommaire: J. S. Redpath Limited, an underground contractor with a worldwide presence, has implemented innovative techniques in various projects in Canada to shorten the development cycle. Conventional methods currently used for installing primary ground support are compared with the Australian technique of bolting and meshing with jumbos equipped with twin telescopic booms, in-cycle shotcreting, and the use of two jumbos and two scissor bolters set up side by side in wide headings. Recommendations and...

Sommaire: Advances in technology provide educators with valuable tools to enhance their teaching and efficiently deliver content to larger audiences. University educators are often encouraged to become more “research intensive” and to increase student enrollment. Faced with these pressures, there is a tendency to use technology to improve teaching efficiencies rather than to enhance existing teaching approaches. Practical learning in applied engineering courses would suffer greatly if hands-on...

Sommaire: Hydraulic fracture (HF) growth through naturally fractured rocks challenges the development of accurate predictive HF models. The authors present laboratory experiments differentiating behaviours associated with orthogonal and oblique intersections between HFs and natural fractures (NFs). HFs were created in sandstone and crystalline (gabbro) rock specimens, impinging orthogonally or obliquely on an unbonded machined frictional interface. Ultrasound monitoring was used to observe the rate of...

Sommaire: A heptapeptide library displayed on M13 bacteriophages (phages) was screened to identify peptide sequences able to selectively bind to gold, chalcopyrite, sphalerite, pyrite, and silica ores, and to evaluate phage potential as bioflotation reagents. Many peptide sequences were isolated through biopanning and differed from known sequences. Adsorption isotherms were determined and a receptor/ligand interaction model was identified and used to compare affinity of peptide sequences toward ores....
