METHOD OF RECYCLING AND PROCESSING WASTE BATTERY

摘要

A method of recycling and processing a waste battery. The method comprises the following steps: (1) preparing a waste battery, additionally preparing a slagging agent containing at least 10 wt.% of Si and/or Mn; (2) adding various prepared materials to a smelting furnace so as to generate an alloy containing Co and/or Ni, and slag containing Mn, and dust; controlling a partial pressure of oxygen, a smelting temperature and duration time in a smelting furnace, such that a generated Mn-containing slag contains ≥ 15 wt.% of Mn, ≤ 5 wt.% of Fe, and ≤ 30 wt.% of Al2O3, and 0.2 ≤ Mn/SiO2 ≤ 3.0.
