Nickel-metal-containing solids for use in manufacturing nickel metal complexes are disclosed. The nickel-metal-containing solids are made by reducing basic nickel carbonates. By varying the molar ratios of carbonates and bicarbonates to nickel salts, the methods provide basic nickel carbonates that produce superior nickel metal-containing solids that react more effectively with phosphorous-containing ligands. The phosphorous containing ligands can be both monodentate and bidentate phosphorous-containing ligands.

An ammonium carbonate leach solution containing dissolved nickel and/or cobalt values is sprayed into a flash chamber to flash a portion of the ammonia therefrom, resulting in the production of a fine precipitate of nickel and/or cobalt carbonate. The solution is introduced into a stripping tower wherein remaining ammonia is stripped therefrom to precipitate further nickel and/or cobalt carbonate on the previously precipitated carbonate, which function as nuclei to reduce deposition in the column.
55 Method for contact between fluids US37626673 1973-07-03 US3905900A 1975-09-16 GULYAS JAMES W; VYDRA CHARLES
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.
