FIELD: mining engineering.
SUBSTANCE: method includes crushing of coal to 6-10 mm, loading it onto a grid in metal airtight reservoir with a branch pipe, without water contact, heating up to 135-140°C and holding till complete evaporation of water, wherein heated steam passes through coal layer and through the branch pipe with its condensation in assembled cooled reservoir with sorbent suspension, collecting gold in volatile form transferred from coals.
EFFECT: selective extraction of gold from brown and stone coals without disturbance of their mineralogical and chemical composition.
