WERKWIJZE VOOR HET NEERSLAAN VAN EEN METAAL UIT OPLOSSING.

摘要

A precipitation method is provided in which a metal is precipitated from a solution of the metal which comprises, introducing into a solution of a first metal discrete particles of metal to precipitate the first metal from the solution, and maintaining the metal particles in motion effective to release precipitated metal deposited on individual portions of the metal particles; for example the metal particles may comprise non-powderous pieces of iron for precipitating copper from solution; desirably the motion if effected by subjecting the metal particles to a vibrating motion, in a vibratory reactor having a frequency and amplitude such that individual portions of metal particles are maintained in constant motion and collide with each other.
