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.
Using modern machine learning techniques and analytical tools, the intern will create a joint recommendation and inventory management system that will be able to automatically choose the ideal package for Chic Maries customers. This package will include curated clothes for each customer based on their tastes, buying history and any other data they wish to provide. These selections will then influence what merchandise Chic Marie will purchase from suppliers, ensuring an optimal level of inventory and efficiency from supplier all the way to the end user.
With increased emphasis on water quality in the Lake Winnipeg watershed, more stringent guidelines for wastewater effluents are being implemented. Smaller municipalities and remote communities, with limited financial resources, will be facing regulatory pressures, particularly around discharge of phosphorus, as well as micropollutants such as estrogens, pharmaceuticals and pesticides. To ensure the release of high quality wastewater effluents post-lagoon treatment technologies such as subsurface filtration systems are being employed for enhanced removal of pollutants.
Klashwerks is an Ottawa-based engineering design and Technology Company founded in 2016 that focuses on the emerging connected car market. They are currently developing an intelligent driver companion for smart car. One desirable feature of this product is to offer the possibility to drivers to interact with the device by simply using their hands. Gestures constitute indeed one of the most powerful modality for humans to interact with computers.
Since energy is the major concern in current and future mining operations, energy efficient technologies are a major focus for research and development. The CAHM machine was developed based on principals of energy efficient particle breakage by compression. The machine design was based on computer simulation and modeling results indicate the potential to reduce comminution energy requirements by 50% as compared to present technologies. CAHM simulations show that the technology can achieve high reduction ratios, consuming less specific power, which translates into energy efficient operation.
Cu and Ni minerals that have great economic value mostly exist in the form of sulfides, making them difficult to extract using hydrometallurgical processes. Currently, heap leaching is the most economical way to extract these metals from low grade ores. Copper recoveries of many chalcocite heap leaches report around 70% copper recovery. However, the chalcocite leaching reaction has several stages. The first stage leach is characterized by 50% copper extraction and the conversion of chalcocite into a second stage of covellite (CuS) which is very difficult to leach at ambient temperature.
With the current challenges with depleted reservoirs and problems associated with heavy oil production, the implementation of the most cost-effective and feasible enhanced oil recovery method is inevitable. There are a wide range of EOR methods available and developed, which are in most cases expensive and complicated to carry out. Therefore, an extensive preliminary screening procedure is necessary before conducting a field-scale EOR method.
Understanding and measuring nitrogen supply in agricultural soils is a critical component in managing groundwater quality and minimizing impacts on the environment. Degraded water quality, primarily as nitrate contamination, is a growing concern in Atlantic Canada and agricultural fields are potential point sources. This project proposes to develop a baseline dataset from agricultural fields across Nova Scotia toward developing a soil nitrogen supply index that will help producers make better crop fertilization decisions.
Hydrofaction™ is Steeper Energy’s proprietary hydrothermal liquefaction technology that converts low value biomass residues to renewable crude oil using supercritical water and homogeneous catalysis. Steeper Energy Canada (SEC) is focused on identifying optimal pathways for upgrading Hydrofaction™ Oil into renewable diesel and jet fuels. Amidst plummeting crude oil prices, such renewable fuels still command attractive ‘green’ economic premiums as well as policy support for their climate and rural development deliverables.
The Project’s objective is to continue the upgrading work executed in the previous MITACS Converge project with a larger focus on more challenging biocrude oils such as heavy fractions, high viscosity, high nitrogen, high ash oils that are produced from feedstocks such as “feed gate residues” in the form of manures, biosludges and organics from municipal waste. The performance objective remains to optimize and scale up the upgrading of Hydrofaction™ Oil to blendstocks for transport fuels.
