The reduction of chromite in the presence of silica flux
As mentioned earlier above, the effect of silica addition on reduction of chromite at 1300 °C was minimal at all the particle sizes and at all levels of silica addition.At higher temperatures of 1400 °C and 1500 °C, the influence of silica was strong at an optimum level of 7.5% addition.A typical plot is illustrated in Fig. 1.The results for 1400 °C and 1500 °C were …
