Acid mine discharge water treatment using slag sources from across North America have seen widespread application principally because its alkaline nature and low cost. The application of slag for neutralization of acidic streams competes with well crushed limestone and residual products such as fly ash. Nearly all of the slag generated for this use in North America is produced from the production of iron and steel. Slag from blast furnaces, basic oxygen furnaces and electric furnaces all have different qualities and characteristics that can impact the application of slag for acidic wastewater treatment. This presentation will shed some light on the different types of slag production methods and describe the selection of slags for treatment of acidic mine wastewaters and why some sources are better than others.
