A review of copper–arsenic mineral removal from copper

Mineral systems of copper sulphides and copper–arsenic sulphides were tested, including a 1:1 mix of tennantite and chalcopyrite. The copper minerals could be separated from the copper–arsenic minerals due to more collector adsorption and less oxide/hydroxide species on the surface of the copper only minerals. It was likely that the surface

Arsenic in Copper Concentrate

Tennantite and enargite as well as Freibergite are copper arsenic sulphide minerals that respond to flotation in a similar manner to other copper sulphides. As such, depression of these minerals would tend to result in depression of other copper sulphides. In this case arsenic comes Copper Arsenic Species called Enargite and Tennantite. These

The surface minerals would contain some native copper and oxidized minerals, but much of the copper and other minerals would have been washed further into the ore body, forming a secondary enrichment zone. This includes many minerals such as tennantite, with their arsenic, copper and iron. Thus, the surface deposits would have been used first

Twinning is common for enargite and can form a nice star shaped cyclic twin called a trilling. Enargite is related to the rare mineral wurtzite. Wurtzite is a zinc sulfide with a formula of ZnS. In enargite 75% of the zinc atoms are replaced by copper and 25% of the zinc atoms are replaced by arsenic, Cu3AsS4.
