Deposit type

  • Bauxite

Summary:

The bauxite deposits within the Compagnie des Bauxites de Guinée (CBG) lease are of two general types.

TYPE 1: In-situ laterization of Ordovician and Devonian plateau sediments locally intruded by dolerite dikes and sills.

TYPE 2: Sangaredi type deposits are derived from clastic deposition of material eroded from the TYPE 1 laterite deposits and possibly some of the proliths from the TYPE 1 plateaus deposits.

Bauxite occurs as a paleolaterite profile developed at an angular unconformity between underlying late Triassic to early Cretaceous sediments (parent rock sequence Biyadh Formation) and the overlying late Cretaceous Wasia Formation (overburden sequence).

Processing

Summary:

The bauxite is transported by railway cars approximately 135 km away from Sangaredi to Kamsar.

At Kamsar, the raw material is crushed in a giant workshop and handled to the production control stocks or to the drying kilns. The crushed and dried bauxite is then sent for loading onto ships with capacities ranging from 50 to 70 thousand tonnes on average.

In Kamsar, the installations include the following assets: locomotive repair shop, railway cars unloader, primary crusher, secondary crusher, scrubbers, conveyors, stacker, reclaimer, bauxite dryers, dry bauxite storage, bauxite sampling tower, power house, wharf, ship loader, etc.

The crushing plant is used only to reduce oversize material – no screening required. Four bauxite dryers are installed in order to reduce the moisture content of the bauxite before shipping.

With the expansion of our operating capacities, we will produce up to 19 million tonnes per year in the first phase, 25 milli ........
