Hydrometallurgical processing makes it possible to precipitate nickel on the surface of different solid materials (powder, hollow granules, particles in the form of threads, etc.). The particle size of the powder produced is determined by the size of seed powder top-charged in the autoclave and ranges from 20 to 2000 μm.
