alumina bauxite production plant design

By 1952, this technology was realized on an industrial scale at the restored Volkhov aluminum smelter. A process flowsheet for alumina production using nepheline ore is shown in Figure 1. 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.
