Definitions
- This invention relates to a process for the separatio of nickel contained in nickeliferous cobalt alloys or other metallic substances.
- the said alloys Or other metallic substances may contain other metals than nickel, such as iron, zinc, manganese, copper, lead.
- the object of the present invention is to effect a separation as complete as possible of the nickel from the cobalt contained in the primary materials.
- the present invention consists in a process for the separation of nickel from cobalt contained in primary materials, which comprises forming a nickel-cobalt alloy and adding a dilute acid and sulfur to the primary material, heating the mixture, precipitating nickel in the form of nickel sulfide, and separating the precipitate from the resulting solution containing the major part of cobalt.
- the presence of metallic iron may be advantageous; the presence of other metals may also be beneficial.
- the acid used for dissolving the primary material is preferably sulfuric acid or hydrochloric acid.
- the pH of the solution during the treatment should be maintained below 7, preferably between 1 and 5. At the end and/or during the treatment (or each partial treatment when the process is carried out stepwise), it is advantageous to allow the pH to rise once or several times to 3 or more.
- the amount of sulfur used may vary within wide limits according to the percentage of Ni and of other metals capable of becoming combined with the said metalloid and which are present in the alloy or other metallic substance.
- the sulfur may be added either wholly at the beginning of th operation or after partial dissolution, orvprogressively during the whole operation or part of it. If the treatment is carried out stepwise, the addition of sulfur may be effected in any of the said ways during each partial treatment.
- a wetting agent may be added in order to facilitate the dispersion of the metalloid. For instance, about 0.1% of an alkyl-sulfonic compound may be used.
- elemental sulfur use may be made of a compound of sulfur producing insoluble nickel sulfide during the reaction. For instance, use may be made of SOz-gas injected into the solution, or of a sulfide or hyposulfite. The elemental sulfur or sulfur compound necessary for the reaction may already be present in the primary material used.
- a solution may be obtained containing a ratio of Ni/Co as low as 0.05/ 100 or even lower.
- the yield of the cobalt extraction i the form of a solution free or almost free from Ni varies. among otherfactors, with the solubility of the alloy or other metallic substance. It may exceed to
- the cobalt contained in the nickel precipitate may be separated by any known method, for instance by means of chlorine or hypochlorite after dissolution of the nickel precipitate.
- Example 1 400 gramsv of an alloy containing:
- the duration of the operation was 4 hours
- the product of the reaction was filtered and washed. 2.6 liters of a solution were obtained, containing per liter 50.9 grams of Co, 49.2 grams of Fe, and 0.07 gram of Ni.
- Example 3 200 grams of an alloy as in Example 1 were introduced into 2 liters of a solution as in Exe ample 2, and were treated at 95 C. with 16 grams of flowers of sulfur of 270 mesh and 2 cc. of a wetting agent. 24 grams of H2804 were added and the solution was stirred for one hour at the same temperature. The pH rose to 3.4 and the mixture was filtered and washed. A first solution was thus obtained containing 53.7% of the total cobalt in the alloy and in the primary solution, with a ratio Ni/Co of 005/100.
- the final residue contained 8.5% of the total Go of the alloy and of the primary solution with a ratioNi/Co of 8.38/100.
- the two first solutions mixed together contained 85.5% of the total cobalt of the alloy and of the primary solution with a ratio Ni/Co of 0.0M 100,
- the three solutions mixed together contained 91.5% of the total cobalt of the alloy and of the primary solution with a ratio Ni/Co of 0.07/100.
- Example 4 400 grams of an alloy containing:
- the Residue II contains:
