For example: How is the Full-Scale XRF sorter mechanism? Is it possible to use it to sort low-grade copper minerals?
The normal copper ore contains chalcopyrite (CuFeS2) with lower than about 2 %.
Dear Ali Behrad Vakylabad many thanks for posting this interesting technical question. As a synthetic inorganic chemist I'm certainly not a proven expert in this field of research. However, I can suggest to you the following potentially useful article which might help you in your analysis:

I hope this helps. Good luck with your work and best wishes, Frank Edelmann
El XRF, es un analizador portátil no destructiva que sirve para medir la composición de elementos, desde 1 ppm hasta el 100% y pueden ser utilizados in situ, es posible ser utilizado para determinar el % de ley y no para clasificar minerales de Cu de baja ley.
