Description
Claims (5)
- 銅とモリブデナイトを含有する鉱石を粉砕し、浮遊選鉱に付して総合浮選と優先浮選を行う際に、総合浮選での浮上物を粉砕して優先浮選を行い、優先浮選で得られた浮上物を20μm以上75μm以下の範囲の粒度で分級して、粗粒側にモリブデナイト精鉱を得ることを特徴とするモリブデナイト含有銅鉱石からのモリブデナイト回収方法。
- 前記総合浮選での浮上物を80%通過粒度で10μm以上100μm以下の範囲の粒度に粉砕することを特徴とする、請求項1に記載のモリブデナイト含有銅鉱石からのモリブデナイト回収方法。
- 前記総合浮選での浮上物を湿式により粉砕することを特徴とする、請求項1又は2に記載のモリブデナイト含有銅鉱石からのモリブデナイト回収方法。
- 前記優先浮選で得られた浮上物を湿式により篩を用いて分級することを特徴とする、請求項1〜3のいずれかに記載のモリブデナイト含有銅鉱石からのモリブデナイト回収方法。
- 前記分級により細粒側に得られた回収物を更に浮遊選鉱に付して精選を行い、モリブデナイト精鉱と銅精鉱とに分離することを特徴とする、請求項1〜4のいずれかに記載のモリブデナイト含有銅鉱石からのモリブデナイト回収方法。
