Abstract
Manganese dry cells sorted out of used-up dry cells are crushed and sieved to obtain a mixture composed predominantly of anodic substances, which is in turn used for ferrite production. The invention is preferable for a saving of resources and preservation of the environment, and enables ferrites on a practical-enough level to be obtained.
