Abstract:
     The new nickel oxide ore treating process has synthesized chemical metallurgy and ore dressing technology. The technological process includes crushing ore, grinding ore into ore pulp, magnetically separating out strong magnetic mineral, heating ore pulp and leaching out with concentrated sulfuric acid, adding sulfurizing agent for chemical reaction to produce nickel sulfide precipitate, and floating out nickel sulfide concentrate. The technological process is simple, low in production cost, high in nickel oxide leaching rate, effective utilization of resource and environment friendship.
