Low-temperature atmospheric plasma in the complex processing of hard-beneficiation mineral raw materials

This report provides a brief overview of the main results of theoretical and experimental studies of the processes for the induced structural modification of the surface state, physicochemical and technological properties of non-ferrous and noble metals minerals when exposed to high-power electromagnetic pulses and discharge low-temperature plasma. The main results obtained to date in the field of application of low-temperature plasma from a high-power (high-voltage) pulsed-periodic nanosecond spark discharges (HPEMP) and dielectric barrier discharge (DBD) in air under normal conditions in mineral processing processes reviewed. The high efficiency and possible restrictions of application of the pulsed energy impacts and low-temperature plasma treatment of geomaterials (minerals, rocks and ores) are demonstrated in order to improve the processing efficiency of the difficult-to-enrich mineral raw materials.
