摘要：

Mathematical correlations were developed to represent the size distributions of high-grade (72%) copper matte particles oxidized under flash-converting conditions in a large laboratory furnace. The correlation parameters for the oxidized particles were expressed as functions of the operating conditions in the furnace, namely, the mean size of the feed material and the oxygen-to-matte ratio. The statistical correlation parameter r2 obtained with the mathematical expressions averaged 0.95 for the feed particles and 0.99 for the oxidized particles. The mathematical correlations were used to compute the amount of dust generated during the experimental runs. Good agreement between the correlated values and the experimental data was obtained. The potential application of the mathematical correlations for an industrial operation is discussed.
