Mechanochemical Treatment to Remove Arsenic from Copper Ore

This study tested the removal of arsenic from copper ore concentrate via a mechanochemical treatment by planetary ball milling. The harmful components of ore, such as arsenic, are increasing year by year and decreasing the copper grade, therefore there is a strong need to improve the separation of arsenic from copper ore. The effect of grinding as a result of chemical activation caused by ...

Arsenic in Porphyry Copper Deposits: Economic Geology of a ...

Air pollution caused by the smelting of ore concentrates from porphyry copper deposits represents a serious environmental problem. Porphyry copper deposits can be grouped into an arsenicpoor class, without arsenic minerals, and an arsenicrich class, of equal size, with arsenic minerals. Tennantitegroup minerals are the most frequently observed arsenic minerals; enargite/luzonite and ...

XPS results have shown that the better mineral separation obtained in this study with H 2 O 2 results from the surface of the arsenic minerals being more oxidised than the nonarsenic minerals. Arsenic oxides are more stable than copper oxides at pH but they dissolve less than copper oxide in the presence of EDTA at pH
