currently reused in several applications including as a cement additive and in place of gravel. Portside_x000D_
Aggregates Ltd. has a contract with Nova Scotia Lands Inc. to process and sell all slag material left on the_x000D_
former steel plant and coke ovens sites in Sydney, Nova Scotia (NS). Air-cooled blast furnace slag (ACBFS),_x000D_
which comes from the smelting of iron from iron ore, has been more studied than open hearth slag (OHS) and_x000D_
reuse avenues have been established for this higher calcium content waste slag material. In contrast, OHS has_x000D_
not been as well researched and active markets for reuse of this waste by-product of steel manufacturing are_x000D_
limited. OHS a lower calcium content and contains more iron than ACBFS, limiting its reuse options. In this_x000D_
project, OHS from over a hundred years of steel making in Sydney, Nova Scotia will be tested for its ability to_x000D_
remove metals and acidity from coal mining wastewater and compared to the better-understood ACBFS. Two_x000D_
treatment processes will be tested, an active treatment process where energy is required for mixing of the slag_x000D_
with the mine wastewater, and a passive treatment process that could be used to line drainage systems from_x000D_
abandoned mines. Given that OHS is a resource Portside Aggregates is interested in being able to exploit,_x000D_
finding new markets for this material through the technical expertise and resources available at the Center for_x000D_
Water Resource Studies (CWRS) at Dalhousie University will be beneficial for the company and the_x000D_
community by increasing potential sales and restoring the environment., program purpose french : Slag is a granular by-product of the steel-making process composed mainly of calcium and silicon oxides and is_x000D_
