Zayıf ve karmaşık cevher işlemelerinde, binlerce ve hatta milyonlarca ton değerli metaller atık formunda kaybolur. Metallerin bakteriyel liçlenmesi bu

kayıpları azaltır. Bu işlemin temeli, on yedinci bakteride bulunan sülfidik minerallerin oksidasyonuyla yapılır. Böylece çözünmeyen sülfidik formdaki

metaller, suda iyi çözünür olan sülfatlara geçer. Sülfatik çözeltilerden metaller sedimantasyon, ekstraksiyon, emilim ile ekstrakte edilir. Aktif bir

şekilde bakır özütleyen bakteri suşlarına dayanan biyolojik bir ürünün varlığı ve zenginleştirme atıklarından metallerin çıkarılma olasılığının temel

koşuldur.

Anahtar Kelimeler

Bakteriyel liç, Thionew bacteria, liç ceviz, zenginleştirme atığı
