Abstract

Leaching and dissolution of synthetic digenite or anilite, in acidic ferric sulphate solution, produce metastable polymorphs of geerite, yarrowite, spionkopite, covellite and CuS (sub 2) . These transformations were produced at leachate concentrations >10 (super -3) M. In weaker leachates, digenite and anilite structures alternate in a constant time-cycle, in which digenite grains first leach to anilite and then quickly return to the digenite structure. Using synthetic chalcocite, at least two leach paths are observed: 1) in weak solutions (= or <10 (super -2) M), chalcocite leaches to tetragonal-phase chalcocite and then to digenite, following the digenite leaching paths from that time onward; 2) in stronger concentrations, synthetic chalcocite leaches directly to djurleite. With continued leaching, the resulting phases have the optical properties and XRD patterns of spionkopite and yarrowite. Under special conditions covellite is formed.
