Abstract
The reduction characteristics of Lampung (Sumatra) lump ore uses carbon monoxide have been studied by thermogravimetry. The course of reaction has been expressed in term of degree of reduction defined as weight loss measured at a given time with respect to the maximum possible weight loss. The results of the reduction characteristics of the ore have shown that the presence of goethite. identified by X-ray diffraction, in an essential magneto-hematite ore complicates the reduction. Some fixed time reduction experiments have been candied out on ore samples where the reduced sample was examined under optical and SEM and also some physical properties were measured. The resulting reduction and porosity curves shows considerable variation behaviour and reflect the physical variation in the individual ore.
