METHOD FOR GEOCHEMICAL ORE TREATMENT OF SUBSTANDARD, REBELLIOUS ORES

摘要

FIELD: mining. SUBSTANCE: layer of rebellious substandard ores is placed on prepared base. A layer of slightly dissolvable salts that may increase their volume at crystallization is formed on the surface of the first layer. The salts are dissolved, transported and precipitated in massif of substandard ores inside rock lump in storage under action of atmospheric deposits or water fed from a source. On stopping water supply the salts are precipitated and concurrently their volume is increased that results in rock bulk destruction and opening finely dispersed minerals. Water is supplied in pulsed manner. EFFECT: storage of substandard ores. 2 cl, 1 dwg
