Abstract
A lateritic ore reduction process wherein a light, low sulphur-containing naphtha is employed to produce a pre-reduced calcine and a heavy residual fuel is utilized to provide the energy to subsequently melt the calcine, and wherein both operations are carried out at a location remote from a source of the fuels required. Two different fuels are mixed at the source to form a blend, which is pumped, at ambient temperature, through a single pipeline to the ore reduction plant. The blend is fractionated into two products required for two or more operations in the ore treatment, and the two product fuels are consumed substantially in their entirety in the respective operations.
