Improving Automated Clay Seam Tracking for GPR-on-borer Systems Used in Potash Mining

This project will attempt to improve knowledge of the condition of the roof of mining rooms in potash mining. Typically a Ground Penetrating Radar (GPR) systems pointing overhead and connected to a mining machine is used to assess the conditions of the roof. This is important in order to avoid rock falls which endanger lives, equipment and the operations of potash mining.

A study of the hydrogeotechnical behavior of in-pit tailings and their interaction with the contact structures - Year two

Mines wastes include tailings and waste rock. Tailings are crushed rock produced by mineral extraction and waste rock is coarse material excavated to create mine openings. These wastes are commonly disposed on the surface in tailings or waste rock piles, which could pose serious environmental and geotechnical issues. Backfilling the openings of underground mines with wastes has become a common practice. The disposal of wastes in open pits is less common, yet is a promising technique.

A fundamental study to better understand how blinding agents interact with particle surfaces in preg-robbing carbonaceous gold systems using electrochemical techniques

One of the most challenging issues in the gold mining industry comes from the carbonaceous ore components adsorbing gold ion complexes, resulting in up to 90% gold loss during cyanide leaching process. The addition of chemical reagents as blinding agents is one of the most promising methods to blind the organic carbon content of ore materials to increase the gold recovery from carbonaceous preg-robbing ores.

Advanced Analysis Setup of Next Generation XRT Algorithms

The research project will include a study using dual energy X-ray transmission (DE-XRT) technology to investigate how to improve the current DE-XRT analysis. To conduct the research, large amounts of samples will be taken from different types of deposits and operations. The research will evaluate various data mining methods to generate algorithms using the data from DE-XRT technology and hence improving the sorter efficiency. The findings from research can help benefit SDE by providing solutions to improve algorithm generation using DE-XRT technology and benefit the mining industry.

Understanding DETA in the Strathcona Tailings Area

Glencore is considering the use of DETA (diethylenetriamine), a mineral processing reagent, to improve process performance in Strathcona Mill, located near Sudbury, Ontario. DETA forms soluble complexes with nickel and copper ions, and can cause the concentration of these metal ions to exceed the value permitted in the final effluent.

Creating shared value with communities in the early Mine life-cycle: The case of Erdene Resource Development Corporation in Mongolia

There is a significant body of research on Corporate Social Responsibility in the mining sector. However, little empirical data exists about what works well across stages of the mine life cycle, particularly during early exploration.

Occurrence and physicochemical properties of organic matter found in phosphate ores

The proposed research project is aimed at detailed characterization of organic matter found in certain types of phosphate ores. The presence of organic compounds often complicates the beneficiation of such ores to produce a fertilizer-grade phosphate concentrate. Further advances in the treatment of such problematic phosphate ores require a thorough understanding of the nature and distribution of organic compounds within phosphate ores.

Corrosion inhibitor for potash mining and processing plants

We propose to mitigate corrosion in potash mining and processing plants by introducing corrosion inhibitor to potash brine solutions. We will screen and formulate a cost-effective corrosion inhibitor that is compatible to potash mining and processing operation, but does not degrade quality of potash products and still provides high corrosion inhibition performance.

Pilot scale process flow sheet development for sustainable recycling of lamps from the waste stream

Lamps and lighting products are the most commonly used electrical product around the globe. With the improvement in lamp technologies, from incandescent bulb to compact fluorescent lamp to LED bulbs, the products have grown complex and hence they require an improved recycling process. In general, lamps consist of various valuable metals such as iron, copper, aluminium, chromium, silver, gold and some hazardous metals such as lead, mercury and arsenic. It also contains plastic and glass.

Investigation of turbulent three-phase flows in the FLSmidth nextSTEPTM flotation cells using CFD-PBM-kinetic simulation framework

The proposed research is aimed at both understanding and improving the flotation equipment design through the development and application of comprehensive multiphysics platform, which has the potential to create more accurate, fundamental basis for modeling, optimization, and scale-up of industrial flotation processes, based on physics rather than empirics and intuition.
