May 27, 2013· Blast furnace slag alumina (Al2O3) is mainly dependent on the alumina content of the input materials mainly iron ore. In those cases where iron ore alumina is less than 1 % the alumina content in the slag hardly goes above 10 %. But in some iron ores (normally found in India) alumina content is 2 % and higher.

Aluminum processing Aluminum processing Ores: Aluminum is the third most abundant element on Earth''s surface. Only oxygen and silicon are more common. Earth''s crust to a depth of 16 km (10 miles) contains 8 percent aluminum. Aluminum has a strong tendency to combine with other common elements and so rarely occurs in nature in the metallic form.

Aluminum: Borates can be used in the actual process of preparing bauxite ore into aluminum. Lowgrade fluoboric acid (HBF 4), produced from hydrofluoric acid and boric acid or boric oxide, is used in the manufacture of cryolite (Na 3 AlF 6) for the electrolytic production of aluminum. The Alcoa Alzak process of electropolishing of aluminum
