The density of the quartz sand and non-magnetic particles are nearly the same, I already tried to separate it in water as a first try, but all particles sunk down. There could be a difference in the densities, but not big enough. So this route can be ruled out at the moment. When there is another method besides density and magnetic separation (because all particles are non-magnetic), please share it with me.

In case of small differences in density, the a centrifuge might be useful

Without knowing the identity of the particles we really can't help. Same for the particle size of the quartz, and the particle size of the desired particles.
Need to know size, identity and density. Then there may be ideas to try.
Thanks for your answers. The best way to separate this kind of particles is chemical. The use of HF in combination with anorganic acids was tested in a publication I found a couple days ago. I'll try to adapt this route to my silica sand, eventually I don't even have to use this type of unclean sand.
