ABSTRACT
This work focuses on the «Metallogenic study of the scale
of the artisanal mine of Kalipopo», with the aspect: cartographic,
lithological, petrographic and metallographic
Indeed, the Kalipopo artisanal mine is located five kilometers
from the town of Likasi on the Kakontwe road axis in the Kalipopo district
precisely in the municipality of Kikula going towards the road which leads to
the company Grande Cimenterie du Katanga (GCK)
It is accessed from Likasi of the woman's monument by taking
Lumumba Avenue which is national road No. 39 towards the Kalipopo district in
the artisanal mining area 499 of Kalipopo, more precisely between 467978 East
longitude and 8785816 North of latitude and 1350m of altitude.
On the cartographic level, the Artisanal Mine of Kalipopo,
starting from its description of the succession of this lithostratigraphic,
carry out by macroscopic observations this of course the presence of the
diggers which ensures that the formations which seem to be hidden in depth are
identified, and also with our studies, we have concluded from bottom to top
:
> The R.2.2 or gray-green dolomitic shale with three levels
of clayey shales, slightly dolomitic, more or less carbonaceous, dark gray to
black in color; 3 to 4m thick
> The carbonate-dominated R.2.1 at the kamoto formation and
at three levels
> R.2.1.3 Cellular siliceous rock: unstratified gray
stromatolitic dolomite 0 to 25m thick
> R.2.1.2 including RSF (Laminated siliceous rock) and D.
Strat (layered dolomite) siliceous dolomites sometimes clayey, very firmly to
well bedded from 4 to 7m thick
> The R.2.1.1 commonly called gray RAT: massive gray
chlorito-dolomitic (0.5 to 4m) and also the presence of a breccia are
mineralized with a thickness that varies between 0 and 13m.
From the mineralization point of view, we have observed in a
macroscopic way, that the mineralization is found much more in :
> R.2.1.3 Cellular siliceous rock > R.2.1.2 in stratified
dolomite
From the petrographic and metallogenic point of view, the
metallogenic studies show the mineralogical association consisting of: bornite
(Cu5FeS4), pyrite (F2S2), chalcopyrite (CuFeS2), hematite (Fe2O3), goethite
(FeO(OH)).
We note that these metalliferous mineralizations (oxides,
sulphurous) are present either in dissemination or in filling in the cracks
more precisely in the RSF and in the D. Strat
To conclude, it should be noted that the copper and cobalt
contents are important to deepen the feasibility studies of a semi-industrial
exploitation, the extraction methods for cobalt and copper.
