| Abstract Scope |
MINTEK in South Africa is investigating the effect of pre-heating on
smelter operations mainly to reduce the electrical energy requirement for smelters. A pilot-scale facility is being developed which includes a one t/h rotary kiln coupled to an electric arc furnace (EAF) optionally served by either an alternating current (AC) or direct current (DC) power supply. The facility also includes integrated materials handling, product handling, and water-cooling systems. It allows for the evaluation of cold vs. hot feed (up to 900°C) on smelter operations over periods of 2–3 weeks continuous operation. The first application will study the effect of pre-heating on
the smelting of titaniferous magnetite (15% TiO2) using a DC-furnace as part of the TiMag project. The second application will evaluate the effect of pre-heating on the production of high carbon ferromanganese (targeting 78%Mn) using an AC-furnace as part of the PreMa project. The paper presents the results of the basic engineering of the project. |
