Definitions

  • U.S. Pat. No. 4,097,575 describes an improvement to the HPAL process which constitutes roasting saprolite ore below about 820 0 C in order to render the ore more reactive with sulfuric acid and then using the roaster calcine to neutralize excess acid in the discharge of an autoclave wherein pressure leaching of limonite ore occurs. Nickel contained in the saprolite ore is largely dissolved during this neutralization.
  • an iron-bearing "seed" material is added to the leach slurry at the start of the saprolite pressure leach stage to accelerate the precipitation of dissolved ferric iron and the extraction of remaining nickel and cobalt from the solid phases.
  • FIG. 2 is a flow sheet showing another embodiment of the process of the present invention in which some of the leach residue is recycled in order to provide seed for iron precipitation.
  • a reductant is added to the limonite leach slurry in order to enhance the dissolution of nickel, and particularly cobalt, from the ore.
  • Most of the cobalt and a smaller proportion of the nickel present in limonite ore is contained typically in a variety of oxidized manganese minerals, referred to collectively as "manganese wad.”
  • Manganese is typically in the tetravalent or trivalent state in these minerals and is refractory to acid leaching unless a reductant is added to cause the manganese to dissolve in the divalent form. The dissolution of manganese is necessary to allow the contained cobalt and nickel to dissolve as well, as will be apparent to those skilled in the art.
  • Suitable reductants include sulfur dioxide (SO 2 ), either as a gas or aqueous solution of SO 2 and ferrous iron, as a soluble salt, e.g. ferrous sulfate, although many other reducing species will also react with oxidized manganese compounds.
  • SO 2 sulfur dioxide
  • ferrous iron as a soluble salt, e.g. ferrous sulfate, although many other reducing species will also react with oxidized manganese compounds.
  • the resulting limonite leach slurry is injected into an autoclave along with the saprolite ore.
  • the saprolite ore typically will be prepared by crushing, grinding and screening or cycloning of the run-of-mine saprolite ore to achieve a particle size that allows the saprolite ore particles to be suspended in the autoclave reactor during the leaching process.
  • the resulting slurry is heated to the desired reaction temperature, for example in the range of 120 to 160 0 C, by any appropriate means, for example by direct injection of intermediate pressure steam into the autoclave, or by direct or indirect steam heating of the leach slurry prior to injection into the autoclave.
  • the autoclave retention time is sufficient to allow most of the iron in solution after the limonite atmospheric leach to hydrolyze and precipitate, and the acid regenerated by iron hydrolysis to react with the saprolite ore, thus extracting most of the contained nickel and cobalt, as well as magnesium and other impurity metals.
  • the saprolite was wet ground to -100 mesh and filtered to produce a filtercake. 262 g (dry basis) of this filtercake was added to the limonite leach slurry, which was then transferred to an autoclave. The autoclave was sealed and heated to 150 0 C, at which temperature leaching was allowed to continue for an additional hour before rapidly cooling the autoclave. The slurry was sampled at the completion of the additional one- hour leach period. The saprolite to limonite ratio was 1.1 and the sulfuric acid addition was 650 kg H 2 SO4 per tonne of ore in this test.
