Process for recycling used-up dry cells, and ferrite production process |
摘要 |
<p>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. <IMAGE></p> |
