flow chart of aluminum hydroxide manufacturing process

Apr 11, 2016 Other major steps in the process are the precipitation of aluminum hydroxide from the sodium aluminate liquor and the calcination of the aluminum hydroxide to produce aluminum oxide (alumina). In this study the minus 1.5″ bauxite ore is ground to minus 3/16″ in a Steel Head Rod Mill operating in open circuit.
