Developments in Arsenic Management in the Gold Industry

2016-1-1  Figure 41.1 presents the Eh–pH diagram for arsenic in water at 25 °C.This diagram was constructed for a total arsenic concentration of 1 g/L or 0.013 mol/L, that is, the concentration of arsenic in equilibrium with a solid phase (such as As 2 O 3) is 1 g/L. The stability of water is shown by the dashed lines, labeled (a) and (b), where the former represents the evolution of

Arsenic in Copper Concentrate - Mineral Processing

2015-9-30  The more Enargite and Tennantite you mine and put in the mill feed, the more you will get in the concentrate. As you see in the historic data her below, if you put 0.07% arsenic in the mill feed, you get about 10X that or 0.7% in the copper conc for the Enargite and Tennantite cannot be separated. Today, the only known way to prevent this type ...
