From the geological setting, Tanzania is endowed with tremendous mineral wealth. The vanado-titanomagnetite ore reserves at Liganga and surrounding area are believed to have excellent range of magmatic associated deposits including Ni-Cu-Co, PGMs and V-Ti magnetite, which could be a major source of iron and steel industry, titanium, vanadium and PGMs for international market. The V-Ti magnetite ore reserves are estimated at between 200-1,200 million tonnes of ore rich in vanadium pentoxide, titanium dioxide and iron ore. PGMs have not been investigated to depth.
The National Development Corporation is desirous of exploiting these deposits to extract economic minerals for downstream value chain.
The Liganga V-Ti Magnetite Ore deposits is located about 850 km Southwest of Dar es Salaam between Latitudes 9°
51´00"S and 10°
00´05"S and Longitudes 34°
51´00"E and 35°
00´20"E. The area can be reached from Dar es Salaam by a Dar es Salaam/Morogoro/ Iringa/Njombe/Mundindi road.
The Government of Tanzania through NDC is now contemplating the future of the Iron and Steel Industry in the country. NDC, which is responsible for investigations and development of Liganga iron ore deposits, has plans to undertake the implementation of this project in stages as detailed below: -
During the initial stage, it is proposed to produce titanium and vanadium concentrates for export market. Accordingly, about 2.5 Million tonnes of Liganga titaniferous ore is targeted for mining to produce the following products: -
- 250,000 tonnes per year of titanium (TiO2) concentrates
- 11,000 tonnes per year of vanadium (V2O5) concentrates
The metallurgical and infrastructural facilities required for the production of vanadium and titanium shall consist of an ore mine, a crushing and comminuting plant, a low intensity magnetic separation plant, an electrostatic separation plant, DC plasma arc furnaces, shaking ladles, water supply, electricity supply and auxiliary facilities including township.
The second stage of the development entails production of 1.0 million tonnes per year of iron and steel products including special steels with an option of expansion. The said volume to be produced at the rate of say 3300 tonnes daily would need reliable means to transport the required raw material to the complex and finished products to consumers through Dar es Salaam, Mtwara harbour and other major towns both for local and export markets.
