Melaconite is a mineral consisting of cupric oxide , CuO. It is known also as black copper ore. In appearance it is strikingly different from cuprite or red copper ore, which is cuprous oxide . Crystals are rare they belong to the monoclinic , or possibly to the anorthic system , and have the form of thin triangular or hexagonal scales with a steel grey color and brilliant metallic lustre. More often, the mineral is massive, earthy or pulverulent, and has a dull iron black color. Hence the name melaconite , from the Greek , black and, , dust, which was originally given by Fran ois Sulpice Beudant F. S. Beudant in 1832 in the form melaconise . The crystallized Vesuvius 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 specific gravity 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.

The mine closed in 1972 and is now flood ed by water . Ruins of the Copperfields mill are present as fountains. It is possible to find ore s and mineral s in the scrap heaps of the old mine such as chalcopyrite , pyrite , bornite , malachite , dolomite , hessite , merenskyite , millerite , palladium , quartz and other minerals. The Lake Temagami Access Road was created to ship ore from the mine site. Copper nickel mineralization at the mine is associated with semi massive to disseminated pyrite at the lower contact between altered gabbro and rhyolite of the Temagami greenstone belt . The gabbro is steeply Strike and dip dipping , approximately 250 m thick and has a strike extent of at least 5 km. The intensity of mineralization varies greatly but is present over most of the defined strike length of the gabbro. Copper is associated with chalcopyrite.

Kipushi is part of the Roman Catholic Diocese of Sakania Kipushi . Kipushi Mine The Kipushi Mine formerly Prince L opold Mine produces copper , lead and zinc . Ore occurs in open spaces and collapse breccia s along a fault zone. The primary zinc rich ore body contains the minerals sphalerite , galena , pyrite , and arsenopyrite , accompanied by renierite , and some germanite and gallite. These minerals were overprinted by a formation of mostly copper rich minerals, including cobalt bearing chalcopyrite , and germanium and silver bearing bornite , plus molybdenite . The ore body is estimated to have contained 70 million tonnes of ore, with an average of 4.8 Cu, 8.8 Zn and 0.5 Pb.
