Beschreibung
Zusammenfassung:	FIELD: concentration of minerals, particularly, leaching of noble metals from rebellious ores or products of their concentration. SUBSTANCE: prior to leaching operation, material is subjected to treatment with magnetic pulse whose intensity amplitude of its electrical component higher than electric strength of ore substance and duration of its front is less than time of formation of spark discharge in air gap equalling the thickness of treated material. To increase effect, use may be made of series of such pulses. EFFECT: higher efficiency of opening of rebellious material containing noble metals due to producing channels and microfissures ensuring access to particles of noble metals by leaching solution. 2 cl, 1 dwg
