EPD Spark-2 test: just 5 pulses with ~250kV to recover spinel - very rare and precious GEMSTONE

Spinel is a rare mineral with a rich palette of shades that can be translucent or opaque. Differs in high hardness, glass luster, octahedral shape. It is not so easy to recover in using common methods like mechanical crusher, jaw-crusher and etc. There is a new approach to extract the mineral crystal from host rock - to strike them with a high voltage pulses in water. #EPDSpark2 #spinelmining #gemstonesprocessing
