Alumina Production in Russia Part I - TMS

The maximum annual output of alumina was 53,000 tonnes. One year later, the Tikhvin alumina plant began production anew, with a capacity of 50,000 t/y. Using a wet sintering process for the processing of high-silicon bauxite, the plant's annual output eventually climbed to 190,000 t/y. The principle flowsheet for the plant is shown in Figure 2.
