Visual Inspection UAV in Harsh Environments and Confined Spaces

Preforming regular visual inspections is essential in up keeping structures. These inspections are used to identify defects at an early stage before they pose a major threat. Unfortunately, these inspections require scaffolding or hiring a boom to access certain areas. Other areas are tight and put the worker at risk. The use of visual inspection […]

Development of activated carbon from petroleum coke and electrolyte design for electrical double-layer supercapacitors – Part 3

Supercapacitors are electrochemical energy storage devices that promise fast charge-discharge rate, high power density, and long cycle life. However, low energy density, high cost, and safety risk of supercapacitors are yet to be addressed in order to deploy the technology into wholesale grid storage. This research project will design low-cost and high-performance electrode and electrolyte […]

Effect of Mineralogy on the Application of Sensor-based Sorting Techniques Year Two

Comminution, the process of crushing and grinding ore to liberate minerals, is the most energy intensive part of the processing flowsheet and accounts for upwards of 75% of the overall energy consumption of the processing plant. Ideally we would only crush and grind those rocks that contain economically extractable amounts of minerals. MineSense has developed […]

A Study of the Modes of Gold Loss in the Calcium Thiosulfate Leaching of Preg-robbing Ores

The evermore increasing complexity of gold ores is forcing operations to seek alternative gold leaching reagents to the traditional use of cyanidation. At the Barrick Goldstrike mine, the implementation of a non-toxic thiosulfate leaching process is about to become an industrial reality. With modification to the existing infrastructure and leaching circuit, this new process allows […]

A Study of Basic Iron Sulfate Formation and Control in the Autoclaving of Argentiferous Sulfide Gold Ore

Autoclave treatment of refractory sulfide gold ores oxidizes minerals, such as pyrite, containing gold that cannot be recovered through conventional cyanidation. Oxidation liberates the gold by putting iron into solution. At high temperature and pressure, the dissolved iron tends to precipitate. A problematic iron precipitate that may form is basic iron sulfate (BFS). In the […]

Pre-Oxidation of a Refractory Sulphide Gold Ore in Alkaline Media

The Eldorado Gold Corp. has developed a method of treating a hard-to-process ore from a mine in China in order to increase their recovery of gold. While this process has proven to be effective, more research is needed on the exact method in which this technique works on a very small-scale and detailed basis. The […]

The management of socio-political risk arising from corporate transitions at mining projects

Changes in management and/or ownership at projects can cause regression in corporate-stakeholder relationships, as the changing faces and attitudes can lead to breakdowns in communication, misunderstandings, and conflict. Failure to maintain positive relationships with stakeholders can lead to significant costs for proponents, and is frequently cited as one of the most pressing issues facing the […]
