FIELD: mining.
SUBSTANCE: method for underground leaching of nickel includes identification of ore structure parametres, tunneling in ore body of mines, supply of leaching solution and collection of productive solution. Part of ore having parametre of geochemical zonality of more than 0.5 is sent to surface, and tunneling of mines in remaining part of ore body, supply of leaching solution and collection of productive solution are carried out when parametre of geochemical zonality of remaining ore is less than 0.8.
EFFECT: increased yield of target product, simplification and reduction of process capital intensity.
