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.

Bauxite
Bauxite consumption per ton of alumina has increased in recent years (from around 2.7 tons in 2005) due to declining quality of bauxite resources and now three tons of bauxite are required to produce one ton of alumina and two tons of alumina are required for the production of one ton of primary aluminum metal.

12.1 Primary Aluminum Production
Primary aluminum production begins with the mining of bauxite ore, a hydrated oxide of aluminum consisting of 30 to 56 percent alumina (A l2O3) and lesser amounts of iron, silicon, and titanium. The ore is refined into alumina by the Bayer process. The alumina is then shipped to a primary aluminum plant for electrolytic reduction to aluminum.

Bauxite is used to produce alumina, which is then used to produce aluminum. Wastes can be generated at several points in the production process, including during the mining of the bauxite ore, and during the refinery production process. The refinery processes used to produce aluminum generates about 2 – 2.5 tons of solid waste for every 1 ton
