摘要

PROCESS FOR REMOVAL OF NICKEL, COBALT AND OTHER SIDE ORE METALS BY BATTERY LEISURE AND PRODUCT CONTAINING NICKEL, COBALT AND OTHER SIDE ORE METALS The present invention is directed to the process for the removal of nickel, cobalt and other metals from nickel in laterals and other metals. as well as product obtained comprising the steps of crushing (I), agglomeration (II), stacking (III) and leaching in piles (IV), the latter being a countercurrent continuous, with two or more stages, presenting two phases, one composed by the ore (solute) and the other by the leaching solution or solvent, which are supplied at opposite points of the series of stages, flowing in opposite directions, and when the leaching of the last stage your solute is removed and new stage introduced in the first position comprising new ore (solute) to be bleached by the solvent solution, which is introduced from the last stage, percolating or flowing through all the previous stages until it reaches the first stage, being separated when loaded with metals of interest (PLS).
