Separation of sediments from alluvial minerals.

  1. Jan 19, 2009 #1

    I am looking for a technique to separate the sediments (Greywacke) which have been deposited on & in some mineral crystals, which are from an alluvial source.

    I have tried immersing them in ethanol, which has helped a lot but not 100% efficient... as some of the microscopic grains have gone inside the crystals which have to be destroyed one way or the other. I thought of immersing them in some sort of acid which would be able to dissolve these sediments, but I am not sure if this is the right procedure.

    I will be really thankful for your kind guidance.

    Prosperous Regards,
