Technical and economic assessment of mercury-containing tailings
Technical and economic assessment of mercury-containing tailings (2009)

The Mercury Waste Management project is amended by a technical/chemical and economic assessment of mercury-containing and mercury-contaminated tailings from the mining sector in developing countries. A feasibility study is undertaken in at least two developing countries that produced/produce precious metals or mercury and are left with mercury-containing tailings.

In the mining sector, mercury has two roles:

  1. Mercury is extracted from cinnabar as a sellable product
  2. Mercury is used in the extraction of precious metals such as gold, silver, copper and others

The project produced the following outputs:
