Speciation of Arsenic in Waste Rocks of Xinqiao Pyrite Mine, Tongling, China

Abstract:

Article Preview

The speciation of potentially toxic heavy metal elements Arsenic in waste rocks of mining activities in Xinqiao Pyrite Mine was studied by conducting improved five step sequential extraction method. The arsenic mainly existed in silicate, secondly in deoxidize, and the exchangeable, oxidizable and carbonate modes content were low. When the waste rocks reacted with the acid mine drainage, the arsenic in the deoxidize and oxidizable modes might easily release from the waste rocks. So the arsenic had high environmental risk.
