摘要：
A flowsheet for the recovery of nickel and cobalt from laterite ores was developed. The flowsheet involves acid leaching followed by hydroxide precipitation of the metal values and then releaching of the hydroxide cake with ammonia. Investigations of the chemistry of extraction of nickel by LIX(R) 84-I and a developmental reagent, XI-84-IT, along with the physical properties of the organic phases are described. Based on these investigations, suggestions with regard to design of a solvent-extraction-plant and operating conditions were made.
