Description
Summary:Mercury compounds are known to be highly toxic, the organic derivatives of mercury being the most dangerous ones for the environment and the living organisms, especially methylmercury CH3Hg+, which is stable and able to accumulate in the objects of the environment. Among the main causes of environmental mercury pollution is gold mining, around which the secondary dispersion halos are formed due to the high amounts of toxic components caused by the nearness of the deposit. These halos are formed as a result of the transportation of metals in dissolved forms in drainage solutions, during the washouts of the waste in flood water and rainwater, and the dusting of the tailings dried part. This article considers the distribution of mercury and its species in the derived matter of the high sulphide tailing of gold mining.
