Sulphate in Mining Wastewater A Question of Mass

Sulphate is a common by-product found in mine impacted water that is increasingly on the regulatory radar as a contaminant of concern. Unlike metal contaminants such as copper that are often present in mining wastewater at low levels from 0.1 to 10 mg/L, sulphate concentrations tend to be much higher and can range upwards of 1,000 to 2,000 mg/L.
