The aim of the current study has been to investigate the influence of mechanical activation through intensive milling of a chalcopyrite mineral sample on its BET surface area and the subsequent effect on its leaching reaction rate and mechanism. Leaching kinetics mechanisms of the raw and mechanically activated chalcopyrite in the sulfuric acid-ferric sulfate media have been investigated. …

Abstract A method of improving leach kinetics or metal recovery from a metal sulfide is disclosed. The method may include an activation step wherein iron in the metal sulfide is exchanged for copper according to the equation: CuaFebSc + xCu2+, Cua+xFeb-(x+w)Sc,,, + (x+w)Fe2+ wherein "a" and "b" are substantially equal to one "c" is substantially equal to two, "x" is 1 0 substantially equal to ...

2. 6. Ball milling Chalcopyrite (2.009 g) and irons (0.673 g) were mixed together using an agate hand mill until a fine powder was obtained. Then, the powder was placed in the milling container made of agate balls of an approximate diameter of 8 mm. The mill changes the direction of rotation every 2 minutes.

A process is provided for the leaching of copper from chalcopyrite using ferric sulfate in which acceptable rates of leaching are achieved by controlling the surface potential of the chalcopyrite to an empirically determined "window" within the broad range of 350 to 450 mV. The most effective process conditions involve the selection of the said surface potential; the leach temperature; the ...
