Al2O4. Al2O3. AL O (OH) and AL (OH)3 Can they be extracted from a powder containing Nepheline?

01 January 2019 1 8K Report

Can Al2O4. Al2O3. AL O (OH) and AL (OH)3 be extracted from a powder containing Nepheline. Can this be done without chemicals? Could it be done by cyclone, sieving or heat treatment. I have large amounts so the process must be scalable.

Thank you. I will have to look at extracting to get a Al that can be used to make aluminium without chemicals. Thank you again.
