Jul 23, 2003Chalcopyrite is the only significant copper mineral and occurs as a replacement deposit in a silica-dolomite host rock. Sulfide gangue consists of pyrite (FeS 2 ) and minor amounts of pyrrhotite and cobaltite. The ore averages eight per cent sulfur. Future ore production will draw increasingly larger tonnages from the 3000 and 3500 orebodies.

The activation energy of chalcopyrite leaching using peroxodisulfate ion was calculated as 41.1 kJ mol⁻. We also report that the leaching of chalcopyrite ore is affected by particle size and that stirring hurts leaching of chalcopyrite. Additionally, we found that peroxodisulfate can produce from sulfuric ions electrochemically.

Reaction kinetic analysis results showed that the different influence of surface reaction and diffusion process on the dissolution of chalcopyrite is little due to the fast leaching speed. After calculation, the activation energy of the whole leaching reaction is 9.06 kJmol −1, much lower than that in other reports.
