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
