Formation of high concentrated solid sludge from acid mine drainage

摘要

As one of the environmental activities of mining, it is important to improve mine water treatment control. Mine water is usually treated in order to discharge to the public water because it is generally contained high concentration of heavy metals with high acidity. The neutralization and settling method has been conventionally applied for this purpose. However, huge amount of neutralizing agents and electricity are consumed in this method to operate the water treatment facilities. On the other hand, to treat large volume of sediment generated from neutralization process, wide area for a tailing dam and considerable energy are required. We have continued to study and apply to improve water treatment technique.
