Gypsum Tailings

The Flat Bay mining district, in St. George’s, Newfoundland and Labrador, is composed of several abandoned gypsum mines that historically produced high quality gypsum to supply the wallboard industry. As a result of this high-grading process, a very large gypsum tailings pit developed from years of screening and washing.

It is believed that the waste pile has large volumes of high purity resource available that once reprocessed, removing insoluble residues such as SiO2, Al2O3, and Fe2O3, it can be exploited. Recently, Vinland Materials Inc. commissioned a study in partnership with the National Research Counsel and the College of the North Atlantic to research an effective commercial reprocessing solution. With the preliminary work completed, VMI is confident that the Flat Bay region can be repurposed and properly remediated.
