Arsenic as a pathfinder element in prospecting

8 Arsenic in prospecting, mining, and markets 5.8.1 Arsenic as a pathfinder element in prospecting 

As discussed in Chapter 3, arsenic commonly occurs in sulfide minerals within hydrothermal and other ore deposits. The oxidation of sulfides in ore deposits and at mines may produce arsenic-rich drainage that results in environmental damage. At the same time, the weathering of arsenic-bearing sulfides in ore deposits may have important applications in prospecting for valuable metals. Due to its close geochemical
