FIELD: mining.
SUBSTANCE: invention relates to enrichment of minerals, particularly, to apparatus for extracting fine gold from clay gold-bearing rocks. Device for vacuum disintegration of gold-bearing clay rocks includes receiver, vacuum pump connected to receiver, working chamber connected by means of short pipeline with high-speed valve with receiver, and having high-speed atmospheric release valve. Ratio of working chamber and receiver amounts is less than 1:200.
EFFECT: device increases output of ultrafine particles of precious metals during their extraction from gold-bearing clay rocks.
