FIELD: mining engineering.
SUBSTANCE: invention is in the field of mineral processing, in particular in processing of gold ore of gangue quartz type of small deposits and ore occurrences. The ore-concentration movable modular complex comprises ore preparation module containing grizzly screen for preliminary screening, double-rotor inertial crusher operating in the mode of recrushing class -350+100 mm, combined impacting crusher intended for fine crushing, counterblow centrifugal crushing machine for coarse crushing, pneumatic separator for processing together with dust collecting and residual fraction discharge system and preconcentrate refining module. The refining module consists of a centrifugal disk breaker for redevelopment of fine-grained gold and spiral pneumatic separator for control processing of fine fractions prepared in centrifugal disk breaker.
EFFECT: improved dry processing of fine-grained gold, production of saleable concentrate of high quality and treatment technology simplification.
