Title:
マンガン酸化物系廃棄物からのマンガン系合金の回収方法
Document Type and Number:
Japanese Patent JP5771031
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To recover a manganese alloy from manganese oxide waste and waste derived from the positive electrode material of a lithium ion secondary battery.SOLUTION: Manganese in battery scrap is distributed to the side of a molten metal phase by smelting reduction utilizing a rotary melting furnace under a non-oxidizing atmosphere, thereby recovering the distributed battery scrap as a manganese alloy. Since battery scrap includes nickel, it is alloyed upon the melting to reduce its liquid phase point, and a recovery operation can be progressed at a relatively low temperature. Aluminum in the battery scrap is not separated, and is used as a reducing agent. Further, silicon scrap derived from a solar battery can be also utilized as a reducing agent, and in that case, the waste of the solar battery can be also simultaneously recycled.
