Miller, Jan D. | Electrochemistry in silver catalysed ferric sulfate leaching of chalcopyrite | Previous investigations have demonstrated the catalytic effect of silver additions in the ferric sulfate leaching of chalcopyrite. CuFeS2 + 4Fe+3 > Cu++ + 5Fe++ + 2S° The enhanced rate of leaching was found to be due to the formation of an intermediate Ag2S film which forms on the CuFeS2 surf... | Reaction; Sulfur; Elemental | 1981 |

Miller, Jan D.; Wan, Rong Yu | Enhanced ferric sulphate leaching of copper from CuFeS2 and C particulate aggregates | Significantly faster leaching kinetics for ferric sulphate are achieved for particulate aggregates of CuFeS2 and C than for CuFeS2 itself. The effect of carbon particles upon the rate of dissolution of chalcopyrite has been increased by a factor of 4 (after 10 hours' leaching), depending upon the ... | Reaction; Chalcopyrite; Electrochemical | 1984 |
