The heavy minerals contained in the oil sands deposits are concentrated by the bitumen extraction/recovery process (en route to oil production). Most of these minerals are contained in the oil sands froth treatment (FT) tailings stream. CVW CleanTech’s process will intercept all the FT tailings before they are discharged into the tailings pond.
Two processing facilities will treat the material recovered. A Concentrator Plant will recover hydrocarbons and water and produce a Heavy Mineral Concentrate. This concentrate will then be separated in a Mineral Separation Plant into final products: a high TiO2-grade ilmenite and a zircon sand concentrate. These processing facilities are planned to be located on or next to an oil sands operator’s site, north of Fort McMurray, Alberta.
The Concentrator Plant
The Concentrator Plant (CP) will recover hydrocarbons and water and concentrate the heavy minerals from this waste tailings stream. The heavy mineral concentrate will then be pumped to the Mineral Separation Plant (MSP).
The Mineral Separation Plant
The Mineral Separation Plant In the Mineral Separation Plant, the heavy mineral concentrate will be separated out as final mineral products, zircon sand concentrate and high-grade TiO2 ilmenite, using differences in these minerals’ high specific gravity and responses to magnetic and electrostatic fields. These mineral products will then be trucked to the CN railhead at Lynton just south of Fort McMurray where they will be railed to North American markets and/or to a port site for export into Asia.
