CESL Process - Teck

Pressure Oxidation: All copper minerals are oxidized into an acid-soluble solid (basic copper sulphate). Example: Oxidation of chalcopyrite (6CuFeS 2 + 7.5O 2 + 2H 2 SO 4 + 2H 2 O -> 2[CuSO 4 2Cu(OH)2] + Fe 2 O 3 + 12S°) The sulphur and the hematite (Fe2O3) solids do not leach or react in the subsequent stages of the CESL Process and are disposed of in their current forms as tails.
