Abstract

The mode of operation of dolomite kilns at a magnesium reduction plant using the Magnatherm process was designed to minimize operation cost and maximize kiln refractory life. Analysis of downstream operation issues shows the quality metric for dolime changed from loss on ignition to specific surface area. This produced a complete change in kiln operation; the net results being major plant productivity increases decrease in operating cost, and increases in both kiln operating costs and reline frequency.
