MELACONITE

This article appears in Volume V18, Page 87 of the Encyclopedia Britannica.

Encyclopedia Britannica - Main :: MEC-MIC
MELACONITE , a
mineral
  consisting of cupric
oxide
 , CuO, and known also as black copper ore. In
appearance
  it is strikingly different from cuprite (q.v.) or red copper ore, which is cuprous
oxide
 . Crystals are rare; they belong to the mono-clinic, or possibly to the anorthic
system
 , and have the form of thin triangular or hexagonal scales with a steel-grey colour and brilliant metallic lustre. More often the
mineral
  is massive, earthy or pulverulent, and has a dull
iron
 -black colour. Hence the name melaconite, from the
Greek
  Eras, black and rthvis, dust, which was originally given by F. S.
Beudant
  in 1832 in the form melaconise. The crystallized Vesuvian mineral was later named tenorite, a name commonly adopted for the species. The hardness of the crystals is 3-4, but the earthy and powdery forms readily soil the fingers; the spec. gray. is 5.9. Crystals have been found only at Mt
Vesuvius
 , where they encrust
lava
 , and in
Cornwall
 . The other forms of the mineral, however, are common in copper mines, and have resulted by the alteration`' of chalcocite, chalcopyrite and other copper ores, on which they often form a superficial coating. (L. J. S.)
