01/07/2011  The major gold-bearing minerals are As-bearing pyrite and arsenopyrite in Carlin-type gold deposits. Because gold- and As-bearing minerals (pyrite and arsenopyrite) correlate positively, As is considered to play an important role in the concentration of Au in hydrothermal systems. When the S content is extremely low, native As would form, such as the case in the Baogutu gold deposit, where ...
