VARIATIONS AND CONTROLS ON THE COPPER/ARSENIC

Copper to arsenic ratios in surface waters interacting with highly mineralized rocks at Furtei are much higher than those expected by stoichiometric dissolution of the main copper-arsenic mineral in the primary assemblage, i.e. enargite. The ratios are also higher than known bulk copper-arsenic ratios of mineralized rock samples.

Mineral Resource of the Month: Arsenic - EARTH Magazine

2014-8-4 · Arsenic is a gray metal rarely encountered as a free element, but is widely distributed in minerals and ores that contain copper, iron and lead. Arsenic is often found in groundwater as a result of the natural weathering of rock and soil.
