Definitions

  • ABSTRACT A method for producing high purity nickel from nickel matte comprising successively the following steps: comminuting and roasting said matte at a temperature near 900C to obtain nickel oxide; dissolving this impure nickel oxide in concentrated hydrochloric acid; oxidating to the ferric state the iron which is contained in the impure solution resulting from the preceding step removing the impurities from this solution by means of ion exchange resin and eluting said impurities to recover cobalt; and subjecting said purified solution to an electrolysis to recover high-purity nickel.
  • the present invention relates to the production of high-purity nickel from nickel matte, whereby the expression high-purity nickel designates nickel with an amount of impurities lower than 0.05wt-percent.
  • Nickel matte contains about 73 to 77 percent nickel and to 23 percent sulfur and is generally obtained by subjecting nickel oxide ore to which a mixture of gypsum and coke is added to a sulfidizing smelting operation in a low-shaft furnace. Iron, a great amount of which is present in the obtained matte, is then burnt by blowing air into the molten matte and turned to slag by silica added during this operation which is carried out in convertors of the Bessemer type.
  • a matte which has been refined on this way presents for instance the following composition:
  • one of the objects of the present invention is to provide a complete method for producing highpurity nickel from nickel matte, which involves lower cost and lower capital investment than do known methods.
  • Another object of the invention is to place an optimum technological solution at the disposal of those skilled in the art.
  • a further object of the invention is to provide such a method which can easily be employed on an industrial scale.
  • Yet a further object of the invention is to provide for the recovery of cobalt contained in the initial product.
  • the method comprises successively the following steps:
  • the elution of the impurities which are retained by said resin during the purification step is carried out in a single step and preferably the resin AMBERLITE IRA 400" is used.
  • AMBERLITE IRA 400" is a registered trade-mark of the Company ROHM & HAAS".
  • the elution of the impurities is carried out in two consecutive steps whereby the first one washes away zinc, copper and iron and the second one allows the recovery of cobalt.
  • the aforementioned resin IRA 400 is preferably used in this embodiment.
  • the process may appear simple, but the process is essentially a combination of steps, several of which are themselves novel, and in each step a considerable degree of care must be exercised.
  • the composition of the initial matte shown as 1 on the drawing, has been given hereinbefore.
  • This matte is first comminuted, either by granulating molten matte or by crushing solidified matte.
  • molten matte flows into a highpressure water stream. to percent of the particles thus produced have a particle dimension lower than 800 microns.
  • solid matte is first coarsely crushed in a jaw-crusher to a size of 80 to mm, then finely crushed in a percussion-crusher till about 40 percent of the particles have the desired granulometry.
  • the use ofa sieve and of a ball-mill completes the comminution.
  • the matte presents now the following granulometry:
  • the comminuted matte is then roasted at 2 at a temperature near 900C.
  • oxide and acid are continuously introduced into one or several reactors in series made of glass-coated steel and provided with means for agitating the mixture and for condensing the vapors.
  • oxide and acid are continuously introduced into one or several reactors in series made of glass-coated steel and provided with means for agitating the mixture and for condensing the vapors.
  • the reaction is exothermal, it is easy to maintain the temperature near 106C with, if necessary, providing a small amount of heat from outside.
  • the acid concentration is near 8 moles per liter and the amount of the hydrochloric solution introduced at 4 is about 1.1 times the amount which is stoichiometrically necessary for dissolving the whole amount of nickel and impurities.
  • the volume of the reactor or reactors is such that the time needed for dissolving the oxide is not longer than 4 hours. In these conditions, the dissolution yield is higher than 99 percent for nickel, iron and cobalt.
  • This method makes use of the fact that the concentration of chloride ions in the solution is not high enough for the formation of a nickel complex. On the contrary, all the metallic impurities like Zinc. iron, copper and cobalt are complexed and thus removed from the solution during the percolation.
  • the first column 811 is then rinsed by means of a concentrated solution of hydrochloric acid containing about 8 moles of acid per liter.
  • the first fraction of the rinsing solution represents the impregnation solution of the resin and is added to the solution to purify 7.
  • the second fraction is substantially only concentrated hydrochloric acid which contains all the metals of the initial solution at a low concentration. This second fraction is advantageously recycled at 4 for dissolving fresh amounts of oxide 3.
  • the impurities retained by the first column 8a are then subjected to elution by means of a diluted solution of hydrochloric acid at a concentration of 0.1 mole per liter.
  • the eluate M contains the totality of the impurities zinc, copper, iron and cobalt. It is then possible to begin with a new purification cycle and to percolate fresh amounts of the solution 7 to purify, but now first on the second column 9a and then on the first column 8a. This operation has been shown by double lines on the drawing.
  • the flow of the solution on the first resin column 8b retains the following impurities iron. cobalt, copper and zinc. As cobalt is the least strongly retained element. it is displaced by the other metals and flows away into the nickel solution. The purification is interrupted when copper flows also away from the resin column 81).
  • the column 8b is then rinsed by hydrochloric acid 3 times normal and regenerated by a decinormal solution of the same acid.
  • the elution solutions are flushed away and the solution containing nickel and cobalt is passed on the second resin column 9b which retains only cobalt.
  • This column 912 is rinsed by hydrochloric acid eight times normal and eluted, which gives a pure cobalt solution, the total recovery yield of cobalt being about to percent.
  • an electrolysis 10 is carried out in both cases by means of insoluble anodes, for example graphite or of titanium anodes. With a current density of 600 A/m'- and a voltage near 4.5 volts, this electrolysis step produces at 11 nickel with a purity higher than 99.95 percent.
  • the chlorine released during the electrolysis step 10 is brought to react at 12 with the same volume of hydrogen for the production of hydrochloric acid which is used at 4 for the dissolution of fresh amounts of oxide 3.
  • a method for producing high-purity nickel from impure nickel matte containing cobalt and other impurities comprising successively the following steps: comminuting and roasting said impure matte at a tempera ture of about 900C to obtain impure nickel oxide; dissolving this impure nickel oxide in concentrated hydrochloric acid: oxidizing to the ferric state the iron which is contained in the impure solution resulting from the preceding step; removing the impurities from this solution by means of a ion-exchange resin to produce a purified nickel chloride solution; selectively eluting said impurities to recover a cobalt chloride solution; and subjecting said purified nickel chloride solution to an electrolysis to recover high-purity nickel.
