The Paleo-Tethys subduction and related mineralization in the SW Yangtze Block: Evidence from the Zhesang Carlin-type gold deposit

Geosystems and Geoenvironment
The Zhesang gold deposit is a Carlin-type gold deposit located in the “Golden Triangle” structural belt of Yunnan-Guizhou-Guangxi. Pyrite and arsenopyrite are important gold-bearing minerals of the deposit.

Arsenopyrite Weathering Products in Barruecopardo Mine Tailings (Salamanca, pain) [PDF]

, 2009
Mining and ore processing, where tungsten is associated with arsenopyrite (FeAsS), produce As-rich mine wastes. Oxidation of arsenopyrite can result in the mobilization and migration of As from these wastes into the environment.
