Hybrid forward osmosis - Freeze concentration process for process water purification and recovery

2019/20 • $125,000 • PI
Zero liquid discharge (ZLD) in chemical and mining industry operations has not been fully achieved yet and fresh water intakes are still high. At the Institute for Water Innovation of the University of Toronto, we recently developed a patented hybrid Forward Osmosis (FO)-Freeze Concentration...

Water in Sustainable Hydrometallurgy

2018/19-2019/20 • $92,000 • PI
With increasing global awareness for the needs of sustainable development, exploitation of natural resources respecting the environmental and societal impacts has become the centerpiece of policy makers around the world. Hydrometallurgy uses water-based chemistry and engineering for metal...

Developing biofilm-based microalgal bioreactors for the efficient production of fuels, chemicals and clean water

2014/15-2017/18 • $472,000 • PI,CO
Using microalgae to convert carbon to biomass is one of the most promising technologies for developing renewable fuels. Algae produces more biomass than conventional crops such as corn and sugar beet, can be used to capture carbon and can be used in water treatment processes. Despite these...

Water in Sustainable Hydrometallurgy

2013/14-2017/18 • $220,000 • PI
With increasing global demand for raw materials, the Canadian metals industry is expanding and investing in new projects around the world. Hydrometallurgy uses water-based chemistry to engineer metal recovery from natural mineral resources and inorganic wastes by employing a variety of chemical...

Bioprocessing of nickeliferous sulphidic wastes from mining activities

2013/14-2014/15 • $140,000 • PI,CO
We propose to investigate the amenability to bio-processing of a metallurgical waste stream produced by the Xstrata Nickel smelting operations in Sudbury, Ontario, namely nickeliferous pyrrhotite concentrate. This is an iron-sulphur mineral (approx. stoichiometry Fe1-xS) that is rejected because...

Application of molten salt hydrates to laterite upgrading

2010/11 • $61,000 • PI,CO
Molten Salt Hydrates (MSHs) are promising media for chemical metallurgical processes. These are highly concentrated salt solutions, for example, molten FeSO4-7H2O or CaCl2-4H2O where the polar water molecule is bound to the salt. This gives MSHs a number of unusual properties that put them in a...
