Apparatus for producing acicular iron or iron alloy particles
First Claim
1. An apparatus for collecting ferromagnetic particles distributed in a strip of metal or metal alloy material, comprising:
- means for electrochemically dissolving said metal or metal alloy material without substantial dissolving of said ferromagnetic particles, said means for electrochemically dissolving including;
a tank containing an electrolyte,a support surface means in said tank being in electrical contact with the dissolving metal or metal alloy material, anda working electrode comprising said support surface means and the metal or metal alloy material; and
magnetic field forming means associated with said support surface means for magnetically adhering dissolved ferromagnetic particles and pieces of metal or metal alloy material having undissolved ferromagnetic particles distributed therein to said support surface means so as to enhance the dissolution of the metal or metal alloy material and to maximize recovery of said ferromagnetic particles.

Abstract
An apparatus for collecting ferromagnetic particles distributed in metal or metal alloy material is disclosed. A tank containing an electrolyte is provided to electrochemically dissolve the metal or metal alloy material without substantial dissolving of the particles. A support surface is provided within the electrolyte for supporting the dissolving metal material and collecting undissolved particles. The support surface further comprises the working electrode in conjunction with the metal material. A magnetic field forming device is associated with the support surface for magnetically adhering undissolved particles to the support surface so as to maximize recovery of the particles.
