Abstract
【解決手段】 本発明のV、Mo及びNi含有廃棄物からの有価金属の回収方法は、V、Mo及びNi含有廃棄物をFeで還元して、V含有スラグ及びFe−Mo−Ni系合金を生成させると共に、前記V、Mo及びNi含有廃棄物中のP成分をFe−Mo−Ni系合金中に残す工程と、前記Fe−Mo−Ni系合金を前記V含有スラグと分離した後、前記Fe−Mo−Ni系合金の脱Pを行う工程と、前記V含有スラグに還元剤を投入してFe−V系合金を生成させる工程と、を備える。
【選択図】 図2
Description
分を酸化物にして除去するのに適した温度であり、950℃以下にするのはMoが昇華して回収率が落ちてしまうのを防止するためである。
,脱Cを行ったFe−Mo−Ni系合金を鋳型に鋳込む。
S2・・・乾燥したV、Mo及びNi含有廃棄物を粉砕する工程
S3・・・粉砕した廃棄物を造粒して団鉱に成形する工程
S4・・・団鉱した原料を焙焼する工程
S5・・・V含有スラグ及びFe−Mo−Ni系合金を生成させる工程
S6・・・Fe−Mo−Ni系合金をレードルファーネルに出湯する工程
S7・・・脱S,脱P,脱Cを行う工程
S8・・・V含有スラグをレードル・ファーネスに出湯する工程
