Tailings water, especially heavy metal ionscontained tailings water, must be treated to the standards before discharge. Leadzinc tailings often contain a variety of toxic heavy metal ions. If entering into the human body through the food chain, it will cause serious damage to plants, animals and people''s health. What''s more, these heavy metal ions will only be transformed in translation ...

Acid mine drainage (AMD), a typical input of tailings dams, commonly has pH values below and is enriched in metals such as aluminium, arsenic, cadmium, cobalt, copper, iron, mercury, nickel, lead and zinc. Iron and sulphur oxidising bacteria, especially Thiobacillus ferrooxidans, can increase reaction rates at low pH by up to six orders of magnitude, thereby accelerating the release of ...

The Hindustan Zinc Ltd (HZL) location at Zawar in Rajasthan, India, includes four mines: Mochia, Balaria, Zawar Mala and Baroi. Mining takes place underground by long hole open stoping. The extracted ore is then crushed and milled before going through a flotation process to produce zinc and lead concentrates. HZL operates zinc concentrators with combined capacity of about 4 MTPA at Zawar.
