text: 1980, anc African production fell by around 14 per cent. The 1981 prices (f.o.b. per 1-ton unit of containec iron) rangec from about 23-34 US cents for fines, 26-35 US cents for lump ore, and 48.5 -56.6 US cents for pellets. 159. Liberian e:xports of iron ore increasec tc 20.3 million ton­ nes in 1981. Mauritanian e:xports rose to 8.9 millicn tonnes, and the producing company ccntinued to develop the Guel bs ma[neti te deposits for procucticn by 1984, to rerlace the declining reser­ ves at Zcuerate. A direct procuction plar:t anc an electric steelmaking furnace were reportecly completed at the Delta Steel Project near Warri in Nigeria ir. 1981. Procuction of pellets ana spOnfe iron was e:xpectec to begin early ·in 1982, using iron ore imported from Brazil and Liberia. 160. Al€eria •s e:xports of· iron ore in 1981 tctallec 1.5 million tonnes, slightly more than in 1980. Dooestic consumption reportedly increased, as a new blast furnace came intc operation. The ole furnace was scheculed for relininf in 1981. Both fur­ naces were e:xpecteo to be in operaticn in 1982, with a total pig iron production capacity of about 2 million tonnes a year. To support increasing domestic consumption, the iron ore production capacity of mines near Ouenza and Bou Khacra was beine raised to 5 million tonnes a year. In : ngola .. iron ore procucti on facilities were being rehabilitated in 1981, anc a production rate of 1 million tonnes a year may be achiever by 1983. During 1981, about 150,000 tonnes of ore were e~pcrtec. This was the first shipment reported since 1975. 161. In the United Republic of Cameroon a corrpany was former in 1981 to stucy the feasibility of commercial eYploitaticn of iron ore deposits near K ri bi. (f) f4aneanese 
analysis: The text appears to be focused on the iron ore industry, discussing production levels, prices, and exports from various African countries. It also touches on the development of new production facilities and the rehabilitation of existing ones. This suggests that the text is primarily concerned with the economic development and natural resources of the region.
