FIELD: geotechnology.
SUBSTANCE: consists in injecting solvent into wells located within the contour and pumping out product solutions from wells located in deepened parts of the bedrock and along the contour of a placer deposit. The production wells pass to the depth of a broken portion of said bedrock. The result is achieved by means of rational distribution of the solvent filtration flow throughout the sand from the injection wells to the production ones.
EFFECT: minimizing the losses of commercial components.
