| Precipitation of solids from a liquid is effected in a confined contact zone by passing the liquid downwardly through a rising stream of hot gas. A number of light weight spheres are confined within and freely movable throughout the zone. The upper and lower limits of the zone are defined by partitions each composed of a horizontal foraminous divider and an imperforate wall. The imperforate wall extends upwardly and outwardly from the divider and terminates at a wall defining the side limit of the zone. The velocity of the rising gas is highest as it passes through the divider and decreases upwardly therefrom. The gas causes the spheres resting on the divider to move upwardly and outwardly until the gas velocity is no longer capable of keeping the spheres in suspension whereupon the spheres fall downwardly along the side wall and imperforate wall scouring solids precipitated thereon.

| PURPOSE: To produce high purity nickel carbonate for plating at low cost by allowing NaOH solution to absorb CO 2 to produce Na 2CO 3 solution and neutralizing this solution with refined NiSO 4. CONSTITUTION: The NaOH solution is allowed to absorb CO 2 gas in an absorption tower packed with packing to produce Na 2CO 3. Refined NiSO 4 is added to produce NiCO 3, which is then filtered, washed with water and dried to obtain high purity NiCO 3. Further, high purity NiO can be obtained by decomposing the NiCO 3 by heat. COPYRIGHT: (C)1990,JPO&Japio | ||||||

| PURPOSE: To reduce the cost by recovering the gaseous CO 2 generated when ZnCO 3 or NiCO 3 is dissolved in an acidic liq., and using the recovered CO 2 as the extractant or neutralizer at the time of obtaining NaCO 3 or NiCO 3. CONSTITUTION: The material contg. Zn or Ni supplied to a dissolver 1A is dissolved in a liq. solvent supplied from a liq. solvent tank 2, the soln. is introduced into an ion-exchange tank 3 through dissolvers 1B and 1C, and metallic Zn or Ni is added. The soln. is then passed through a precipitation tank 4, a precision filter 7, a dissolver 8, ammonium distillation tanks 9A-9C, crystallization towers 10A and 10B, a collection tank 11, and a filter 12 to obtain ZnCO 3 or NiCO 3. The ZnCO 3 or NiCO 3 is supplied to a dissolver 13, and dissolved in an acidic liq. The generated gaseous CO 2 is returned to an absorption tank 14, and absorbed in the aq. ammonia or NaOH recovered in the distillation tanks 9A-9C. The obtained (NH 4) 2CO 3 or Na 2CO 3 is led to the liq. solvent tank 2. COPYRIGHT: (C)1990,JPO&Japio | ||||||

| PURPOSE: To obtain NiCO 3 useful as semiconductor devices readily and stably by adding an alkalizing agent of carbonate to a specific solution to give NiCO 3 precipitate and washing the precipitate with water, adding NaClO to remove a NH 4 compound. CONSTITUTION: NiSO 4 containing 0.3W0.5wt.% NH 3 is dissolved in water under heating with steam to give an aqueous solution of NiSO 4 (A). Then an alkalizing agent is added to component A to give NiCO 3 precipitate (B). Then water is added to the component B, which is stirred about 30min and sufficiently washed with water by decantations of two or more times to remove NH 3 attached to the component B. Then NaClO is continuously added to the prepared component B from which NH 3 is removed under control of ORP (oxidation-reduction potential) until ORP becomes equilibrium approximately at 600mV and the component B is treated until the grade of NH 3 in NiCO 3 becomes ≤0.05wt.% of product standard to give the component B from which NH 3 is highly removed. NaClO is removed from the component B by washing with water to produce NiCO 3. COPYRIGHT: (C)1989,JPO&Japio | ||||||
