Solubilities of the assemblages chalcopyrite (CuFeS 2) + pyrite (FeS 2) + bornite (Cu 5 FeS 4) and copper + chalcocite (Cu 2 S) have been measured in subcritical aqueous solutions of NaCl and NaHS + H 2 S under the following conditions: 200 degrees to 350 degrees C; a range of pH within 2.5 of neutral in sulfide solutions, and 1.5 of neutral in chloride solutions; up to 10.4 m …

 · A hydrometallurgical process for the recovery of pure copper from an intimate mixture of chalcocite and pyrite is discussed. The dissolution of the copper can be accomplished by pressure leaching in an ammoniacal ammonium sulfate solution which results in the production of byproduct ammonium sulfate. In some locations this byproduct is undesirable, and an …

This mineral was known by a wide variety of names previously. In 1868, James D. Dana and George J. Brush renamed this material "chalcocite". Dimorph of: Wuyanzhiite. Chalcocite …

 · Chalcocite Cu x S from organic solution has a resistance of the order of 10 5 –10 6 Ω/sq, while crystalline Cu x S has a resistivity of about 10 7 Ω/sq at 240 °C and 10 2 Ω/sq at 260 °C, respectively. In fact, the samples obtained at 230 and 240 °C, which consist of a mixture of chalcocite and digenite phases, are more resistive than ...
