Definitions
- the metal received as the end product of the manufacturing process would be obtained in some other form than as a uniform solid object, such as a cathode plate.
- a uniform solid object such as a cathode plate.
- Particularly methods where the end product is obtained as pure metal powder would be extremely useful.
- the arrangement according to the invention is an arrangement for producing metal powder by precipitating yield metal powder by mixing dissolved yield metal powder with a solution containing at least one intermediary metal.
- the arrangement according to the invention comprises an electrolytic cell for dissolving the yield metal located on the anode side of the electrolytic cell and for oxidizing it in the anolyte, and for reducing, on the cathode side, the dissolved intermediary metal located on the cathode side of the electrolytic cell; a precipitation chamber arranged essentially separately from the electrolytic cell; as well as means for feeding anolyte solution and cathode solution respectively from the anode side and the cathode side of the electrolytic cell to the precipitation chamber for mixing the oxidized yield metal that is dissolved in the anolyte, and the cathode solution containing reduced intermediary metal, outside the electrolytic cell.
- a correct mixing ratio With a correct mixing ratio and an effective precipitate recovery, the creation of yield metal agglomerates can be prevented in the precipitation step, and consequently the homogeneity of the yield metal particles contained in the powder is enabled with respect to their size.
- a correct mixing ratio also facilitates a process with a better efficiency, which can be utilized for reducing the amount of energy needed in the process for producing a certain quantity of yield metal mass.
- the first part of the starting solution contains intermediary metal for boosting the dissolution of yield metal on the anode side.
- the first part of the circulating solution created as a result of mixing the anolyte solution and the catholyte solution is returned to anolyte.
- the first part of the starting solution is composed of the first part of the circulating solution.
- the second part of the circulating solution created as a result of mixing the anolyte solution and the catholyte solution is returned to catholyte.
- the second part of the starting solution is composed of the second part of the circulating solution.
- the purpose of the diaphragm is to mechanically separate the solutions located on different sides of the diaphragm, i.e. to serve as a mechanical obstacle, while at the same time being electroconductive to that extent that the electrolytic cell is capable of functioning effectively.
- This diaphragm divides the electrolytic cell to an anode part (or anode side), where the anolyte is located, and to a cathode part (or cathode side), where the catholyte is located.
- the anolyte and the catholyte cannot be mixed together without disturbing the anode and cathode reactions, and metal powder cannot be formed in the vicinity of those electrodes in the electrolytic cell.
- the kinetics in the dissolution step are rapid, as the quantity of yield metal dissolved in the anolyte is directly proportional to the charge that has flown through the anode.
- the quantity of yield metal that is dissolved in the anolyte can be efficiently and accurately controlled, which facilitates a more precise control of the process dynamics, and an improvement in reliability.
- the starting solution contains sulfuric acid. Further, in an embodiment of the invention the sulfuric acid content in the starting solution is at least 50 g/l and preferably within the range 50 g/l - 1,500 g/l. In an embodiment of the invention, the starting solution contains hydrochloric acid or nitric acid. Further, in an embodiment of the invention the hydrochloric acid content in the starting solution is within the range 15 g/l - 500 g/l. Yet in an embodiment of the invention the starting solution contains, in addition to hydrochloric acid, also alkaline chloride, the content of which in the starting solution is within the range 15 g/l - 500 g/l.
- a suitable acid, and content for said acid must be chosen so that the yield metal is dissolved from the supply material to the anolyte, instead of the oxidation of the intermediary metal. Therefore the anolyte pH (i.e. oxygen content) must be suitable.
- the oxygen content must be as high as possible.
- the part that is fed as the anolyte may contain intermediary metal in its high potential value.
- the starting solution may contain two or even several different intermediary metals.
- the first and second part of the starting solution are identical in composition.
- vanadium when the yield metal is copper and the intermediary metal is vanadium, vanadium may be oxidized on the anode side 6 into an intermediary oxidation state V 5+ , which is even higher than the V 3+ state, whereafter the V 5+ reacts with copper, thus oxidizing and dissolving copper. Now the "over-oxidized” vanadium V 5+ is reduced back to its original high-potential value V 3+ . On the anode side 6, a corresponding "overoxidation" to an intermediate oxidation state is also possible with other intermediary metals than vanadium.
- the efficiency and reliability of the process it is useful to ensure that any remarkable amounts of V 2+ and/or Cu 2+ cations are not left in the circulating solution.
- the real mixing ratio of anolyte and catholyte can be 1:N, where N > 2.
- the value of the parameter N also depends on how the circulating solution is cleaned before feeding it back to the electrolytic cell.
- the finding of a suitable mixing ratio is obvious routine testing for a man skilled in the art.
- the solid yield metal powder 14 separated from the solution is finished ( Figure 1 , step S6) in a finish treatment arrangement.
- the separation and finish treatment processes can include many different steps, depending on the desired properties of the end product.
- the yield metal powder 14 separated from the circulation electrolyte is washed in water for minimizing impurities carried along from the solution, whereafter the yield metal powder 14 is dried and coated with a passivation layer for preventing an oxidation of the powder, among others.
