I want to separate the individual elements from a sample. Simply without chemicals. The sample includes:
Nepheline 34.5%. Alumina/Aluminium Oxide 14.4%. Anatase, syn TiO2 12.9% and Quarts. It is in powder form. As you can see there are some valuable elements, too good the use as building material.
I require the method to be scalable to industrial scale. Simple and cost effective.

Not sure how you can do it without chemicals. For a simple, scalable, and cost effective technique, try exploiting the difference in solubilty of the various compounds in different solvents (and as a function of temperature); use the difference in solubility as the driving force for separation.
