Abstract

The invention relates to hydrometallurgy, particularly to the process of extraction of nickel, cobalt, and other metals from laterite ores. The process of extraction of nickel, cobalt and other metals from laterite ores includes leaching of the mined laterite in the way of a continuous multistage countercurrent heap leaching. At every intermediate stage of its leaching the leach solution which was prepared from bittern gained at the next stage of leaching of the previous heap is added. On completion of the last stage of its leaching it is flushed, and the bittern gained at the first stage of its leaching is delivered for processing as a pregnant leach solution. The continuous multistage countercurrent heap leaching with such number of stages, which provides the decreasing of acidity of bitterns gained at the first stages of the heap leaching up to the level, necessary for the first stage of processing of pregnant leach solutions. The processing of pregnant leach solutions is made stepwise using ion-exchange resins and ion- exchange processes, arranged into several stages, with getting at every stage of processing the eluate enriched by metal corresponding to this stage of processing, and depleted by other metals. The method increases the completeness of nickel and cobalt extraction from low cost of materials and energy, with a high degree of regeneration of materials and recycling reagents used.
