FIELD: mining.
SUBSTANCE: method of leaching of useful components from ore comprises the preparation of the base ore, laying of ore material, supply of the leaching solutions and collecting of production solutions. From the base ore the briquettes are formed, theirs shape is fixed, and inside each briquette the punched pipe with the connecting branch pipe emerging to the surface is installed. Then the briquettes are laid on the moisture-proof base and they are connected to the main line for supply of leaching solution through the branch pipe. Then the leaching solution is injected inside the briquette for filtrational passing through the briquette material towards the surface and free flow of productional solution along the briquette surface to the moisture-proof base from which it is supplied for extraction of useful components.
EFFECT: decrease of labour input and improvement of efficiency of extraction of useful components from ore material.
