Abstract
Description
[実施例1]
D50が100μmに粉砕した多金属団塊1kg(乾燥状態)を水3.1Lにブレンドする。スラリーを500rpmで連続撹拌し、95℃に加熱する。合計510gのSO2ガスをスラリーに1.5時間吹き込む。その後、H2SO4 280gを、2時間でゆっくり加える。この添加中に、いくらかのSO2が溶液から放出され、その結果400gが効果的に消費される。pHは1.6に達している。スラリーをろ過によって分離する。溶液は、9g/L H2SO4を含有する。固体は洗浄する。
[実施例2]
この実施例は、実施例1に類似している。しかしながら、CaCO3の代わりに再循環させた炭酸Mn及びFeを中和剤として使用する。その結果、セッコウが形成されず、対応するろ過工程が排除される。
