Dear friends
I am working on a project to see the chemical diffrence between the composition of the garnets from various skarn deposits of NW Iran. We have Cu, Cu-Mo, Fe-Mn skarns here. I have got samples from these skarns and also from some baren rocks, e.g metamorphic garnet. The main purpose is to see if there is any chemical differences between these garnets or not. I try to get pure garnet and analyse them by XRF. Microprobe analyses is not good enough since its detection limit (about 500 ppm) is not satisfactory.
Regarding this project, I have a question. How can I separate chalcopyrite from garnet. Do you know any acid which dissolves chalcopyrite but without any effect on garnet. Do you know any reference about this type of projects?
