Electric-pulse disaggregation (EPD) has no alternative by its capability to liberate ideally preserved crystals and monolithic blocks of undamaged gemstones for their use in jewelry. It is used for efficient liberation of minerals from matrix rocks; separation of gemstone crystals from intact minerals; pre-weakening at larger throughput. As environmentally friendly technology it eliminates dust and toxic substances, reduces power consumption, has modest capital and operating costs. Besides, minor security issues - just two operators control one EPD plant/all process products. EPD of CNT Spark-series have simple construction and ease of learning. Same device can be used for:

- R&D/different ores/gemstones; 

- mineral processing and production;

- resources’ valuation;

- quality control of recovery of gemstones by other methods
