Mechanochemical Treatment to Remove Arsenic from Copper Ore [PDF]
Minerals, 2019 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.
