Covellite Investigations on ferric sulfate leaching of covellite (CuS) can be
divided into two groups: those conducted in either the absence or presence of
bacteria. The early investigations on covellite leaching with Fe2(SO4)3 solutions
in the ...

The northernmost vein is the Covellite (or North Grcyrock). It appears to be cut by
a northward-dipping clay slip having a general northwest direction, which
displaces it, shifting it along the fault plane for 50 feet. In the upper levels this fault

oligosulfide series, CuS2, would be similar to one of the two S environments in
covellite, and indeed, a thin CuS-like layer might have been present at the
surface of the chalcocite. Interpretation of the S 2p spectrum for a CuS surface is

Hydrometallurgy: Principles and Applications
Lowe [168] investigated the leaching of covellite in the acid solution of ferric ions
in the temperature range 40–70 °C. He found the linear course of the reaction
rate with the activation energy of 59 kJ/mole. The leaching rate was independent
of ...
