Kinetic studies have been made on the rate of reaction between molten slag and metal with gas-injection stirring. The explored reaction is oxidation of Si in molten Cu by FeO in a Li2O-SiO2-Al2O3-FeO slag taking place under the condition of rate-controlling by Si transport in the metal phase. Kinetic experiments were done at 1250°C. The slag-metal bath was stirred by Ar gas injected through a nozzle located at the crucible bottom. The apparent metal-side mass-transfer coefficients of Si, kSi', are calculated from the kinetic data. Relations between kSi' and experimental conditions (gas flow-rate, Vg ; metal depth, hM; slag depth, hsl ; crucible diameter, dc) have been investigated.<BR>kSi' is found to increase generally with increasing Vg. The dependence of kSi' on the gas flow-rate varies at certain gas flow-rates denoted by Vg* and Vg**.In the low Vg range (Vg<Vg* : Region I), kSi' is proportional to ( Vg/dc2)1/2. In the medium Vg range (Vg* <Vg<Vg** : Region II), the effect of the increase in gas flow-rate on kSi' is cosiderably smaller than in Region I. In the high Vg range (Vg>Vg**: Region III), the extent of the increase in kSi' with Vg increases again. It is also found that kSi' increases with metal depth, hM, below a transitional depth, hM*. Above the transitional metal depth hM*, kSi' becomes independent of hM. Examinations have been performed of the influence of slag depth, hsl, on kSi' in Regions I and II. In Region I, kSi' is independent of hsl. In Region II, kSi' decreases with the decrease of slag depth.
