The specific investigation of the redox conditions of the Green Point Formation sediments will allow modelling the paleoceanographic conditions on a global basis particularly because the investigated formation is the Cambrian?Ordovician GSSP, which adds to the value of the contributions of the study to understanding the global distribution of source rocks around that time interval.
The Barkerville Gold Mine will host an intern to conduct a study to optimize chemical usage to extract gold and treat effluents. The gold mine obtains ore from a range of deposits with different mineralogical properties. The intent is to minimize chemical use and therefore reduce effluent treatment requirements thereby reducing overall environmental liabilities and increasing productivity.
This research focuses on dry comminution technologies and specifically on the Vertical Roll Mill. Goldcorp recently announced a new initiative referred to as H2zero with the goal of reducing water usage in their mining operations by 80 to 100%. The study will compare energy usage in comparison to conventional wet ball mill grinding. The study will investigate the effect of dry comminution with the VRM on downstream flotation by comparing the effects of physical properties of the ground product and surface chemistry in comparison to wet grinding in ball mills.
Dust generated from haul roads poses a health and safety threat to mine sites. Traditionally, water has been applied on mine haul roads to control the dust. Using chemical surfactants to form a solution of chemical suppressants has been considered as a more effective method to control fugitive.
The project involves identifying changes in mineralization during the drilling of the blast holes. During drilling, an experienced driller is able, to a certain extent, to detect signals that indicate that a zone change is occurring: vibration in the cabin, rotation rate, etc.
This project will combine filtration characterization and advanced 3D imaging and modelling of material structures to find ways to improve the recovery of process water from difficult-to-treat tailings that are the by-product of mining and mineral processing. This process is called solid-liquid separation and it is a critical area for the reduction of oil sands tailings volumes. Due to the chemistry and solids composition of oil sands tailings, they are extremely resistant to dewatering.
This research project will focus on analytical techniques related to determining the gold geochemistry of the La Victoria property in the western Peruvian Andes. The La Victoria property is found along a major gold belt that is host to some world class deposits such as Yanacocha, Lagunas Norte, La Arena and Shahuindo. Based on initial exploration techniques, two major mineralized areas (San Markito and Rufina) have been identified as important for gold exploration.
The benefit of ore sorting is rejecting waste material prior to downstream processing. This results in reducing material handling costs and environmental liability, lowering energy consumption, and feeding more consistent and higher ore grades to the concentrator. Sorting allows for a lower cost bulk mining method resulting in lowering the cut-off grade and increasing the resource size. Despite the potential benefits, sorting is not widely applied due to barriers in the current technology.
Mines produce large amount of waste rocks, mostly disposed on ground surface in form of pile. In underground mines, waste rocks are increasingly used to construct barricades to retain mining backfill in the stopes. Waste rocks can also be used as inclusions to accelerate the drainage and consolidation of tailings. To properly evaluate the stability of these infrastructures, numerical models are needed. However, the existing numerical models suffer from two major limitations.
Mineral extraction and processing by mining operations is land, energy and water intensive. Mineral processing is both the single largest end-use of electricity, as well as the most water-intensive stage in the mining value chain. This research will help to tackle the issues of power and water consumption and lead to the development of reductions in land, energy and water intensity at mining operations.
