Electric pulse disaggregation (EPD) provides a fast and efficient means of liberating mineral grains from a rock irrespective of lithology or grain size along grain boundaries (zones of weakness). As a result, individual, undamaged mineral grains get recovered in their original shape. It is essential for mineralogical research and geochronology that EPD does not pose any risk of cross-contamination, does not break rock fragments or mark/damage grains as they are liberated; samples can be disaggregated right inside clean plastic bags which completely eliminates any sample handling mistakes.This also saves processing time since with conventional rock crushers, barren quartz should be disaggregated or crushed as a blank between samples to reduce and monitor contamination. EPD processing plants are also used for recovery of pristine crystals of diamond and gemstones from productive ores.
