​Recipe for heavy mineral separation - from rock to mineral mount

To separate heavy minerals such as zircon, baddeleyite, rutile, monazite etc. from a rock we apply a very quick and simple method only using a hammer, a sieve and a water panning technique. This way, we minimize the risk of sample contamination considerably and we also avoid the use of heavy liquids. The video tutorial below provides detailed guidance on the complete mineral separation process from whole rock to the mineral mount ready for analyses.
