Production of Ferro Nickel or Nickel Matte through a combined hydrometallurgical and pyrometallurgical process

摘要

A process for the production of ferronickel and nickel Matte from a solution of Liquor Product contains at least Nickel, Cobalt, iron and acid soluble impurities in these processes, including the steps of: (a) to come in contact with the solution of Liquor product (7) Contains Nickel, CobaltAcid soluble iron and Impurities with ion exchange resin (8),Where the Resin selectively absorbs nickel and iron in the solution leaving the Cobalt and the acid soluble impurities in refined (9); b) Separating nickel and Iron of the Resin with a solution of sulfuric acid to produce an eluate (11) containing Iron and nickel; c The eluate) neutralizing to precipitate a product of mixed Nickel iron hydroxide (13); (d) Reducing and fuNDIR Product Mixed Nickel iron hydroxide to produce ferronickel (29) or Nickel Matte (24).
