(1) 鉄(III)イオンと、全ヨウ素濃度が8〜100mg/Lであるヨウ化物イオンを含有する硫酸溶液を浸出液として用いて、硫化銅鉱を含む鉱石から積層体浸出法によって銅を浸出させることを特徴とする、硫化銅鉱からの銅の浸出方法。
(2) 前記硫化銅鉱を含む鉱石が、黄銅鉱を主成分とするものである、(1)に記載の方法。
(3) 前記浸出液中の全ヨウ素濃度に対する鉄(III)イオン濃度の割合が重量比で20倍以上である、(1)または(2)に記載の方法。
(4) 前記浸出液への鉄(III)イオンの添加量が、浸出液後中の全鉄濃度に対する鉄(II)イオン濃度の割合(Fe2+/Fe)が濃度比で20%以上になるような量である、 (1)〜(3)のいずれかに記載の方法。
2I−+2Fe3+→I2+2Fe2+ (式1)
[化2]
CuFeS2+I2+2Fe3+→Cu2++3Fe2++2S+2I− (式2)
CuS+I2→Cu2++S+2I− (式3)
また輝銅鉱(Cu2S)と斑銅鉱(Cu5FeS4)は鉄(III)イオン(Fe3+)により酸化されて比較的容易に溶解することは公知であり、ヨウ素を添加することでその反応が阻害されることはない。反応式は(式4)と(式5)に示される。
[化3]
Cu2S+4Fe3+→2Cu2++4Fe2++S (式4)
Cu5FeS4+12Fe3+→5Cu2++13Fe2++4S (式5)
(実施例1)鉱石積層カラムにおけるヨウ化物イオンおよび鉄(III)イオン共存による銅浸出促進効果
模擬鉱として、黄銅鉱を主成分とするカンデラリア産の銅精鉱0.5kgと砂(市販の熱帯魚飼育用砂)9.5kgをミキサーで混合して用いた。この銅精鉱の品位はCu:28mass%、Fe:28mass%、S:32mass%であった。よって、銅品位としては1.4%となる。

低品位硫化銅鉱としてチリ共和国産粗鉱への適用を検討した。この粗鉱の品位はCu:0.8mass%、Fe:5.9mass%、S:2.7mass%であった。
ヨウ化カリウム:130mg/L(ヨウ素濃度100mg/L)
硫酸鉄(III):2g/L(Fe3+濃度)
(浸出条件O)
ヨウ化カリウム 無添加
