Flotation of gold-containing arsenic pyrite (2)

Thus, because during the preparation of floating mineral slurry, soda can play a beneficial role in the -, it is that the metal iron as sodium carbonate inhibitor grinding circuits can ensure there is a higher concentration of dissolved oxygen. This promotes sulfide minerals, including arsenopyrite , which is better oxidized prior to flotation. However, the arsenic concentration in the soda medium is always higher than the arsenic concentration in other solutions , whether during the grinding process (see Table 1 ) or in the flotation machine (see Figures 1 and 2 ). When the pH is the same). This - the facts show that carbonate ions can also play a significant role in the surface structure of the oxidized arsenopyrite.
