FIELD: mining.SUBSTANCE: invention relates to extraction of nonferrous metal ore. Proposed method comprises ore body exposure by the system of injection and evacuation works, feed of leaching solution in evacuation works, forcing the production solution via evacuation works and processing the latter. Deposit is divided in ore blocks to be successively processed. Note here that injection and evacuation works are located across groundwater flows. Note also that nickel-cobalt solution is evacuated in pH range that ensures in-situ settling-out of ballast admixtures, mainly, iron and aluminium ions.EFFECT: lower costs, better ecology.7 cl, 6 dwg, 2 tbl |
