Developments in Arsenic Management in the Gold

2016-1-1  The majority of arsenic emissions, worldwide, are as compounds such as minerals and trioxide. Gold-mining and -processing operations were primarily used for Table 41.2. So, for example, some copper-mining and -processing operations (e.g., Olympic Dam, in Australia) that may produce significant gold were not used in this analysis.
