TECHNOLOGIES FOR REMEDIATION OF WASTE WATER
CONTAINING HEAVY METAL MINING SECTOR RESULTS
The origin of acid mine water with high content of metals is
accelerated oxidation of iron pyrite and other metal sulfides as being due to
exposure of these minerals in contact with oxygen and water, as a
consequence of metal ore processing. There are two general categories of
treatment methods that are well researched: active treatment, which requires
the use of chemical treatment systems for acid buffering and passive treatment,
which allows biological and chemical processes occurring naturally in the
system to operate outside the control of polluted effluent received.
