Separation of Alumina and MgO (1 reply)

I am looking for methods that you may have for the separation of Alumina from MgO. I am working on a design for a refractory brick recycling plant and I need to separate these 2 oxides to have a viable final product.

It is not easy to separate oxides of this nature. Gravity wont work because their density is similar.  You could you pyrometallurgy but that is difficult and expensive.  I think you only option is to use flotation on finely ground material.  This will only work if you are able to work with a fine material for your final product.  Flotation wont be easy for these oxides but it my best suggestion.
