Challenges and opportunities in the removal of sulphate ...

01/03/2018· It was observed that the final sulphate concentration heavily depended on the barium hydroxide dosage. The process was carried out with two types of mine water, namely water from a coal mine and gold mine recording an initial sulphate concentration of 2487 and 4890 mg/L, respectively. The treated solution recorded sulphate values of 181 and 24 mg/L, respectively, which posited an over 90% removal of sulphates …

Sulphate in Mining Wastewater – A Question of Mass | BQE …

04/06/2019· 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. These values are common even after pH adjustment with lime, which is the most common method currently used for sulphate …

01/10/2016· Sulphate precipitation as ettringite is a modification of high pH lime precipitation (Geldenhuys et al., 2003, Tolonen et al., 2015). With precipitation as ettringite, mine water sulphate concentration can be reduced to less than 200 mg/L. This is less than the drinking water guideline in Finland, which is 250 mg/L sulphate (Directive 98/83/EC). When ettringite precipitation is used for waters with high sulphate …

Sulphur Refining of Gold - 911 Metallurgist

23/03/2016· Although gold sulphides may be readily formed in the wet way, they are decomposed into gold and sulphur by merely heating them to a temperature below 300 deg. C. If pure gold is heated strongly with sulphur no combination of the elements appears to take place. Nearly all the other metals at a bright red heat unite readily with sulphur, and form sulphides. If a large proportion of copper be alloyed with gold …

Acid mine drainage - Wikipedia

Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks ...
