CYANIDE DETOXIFICATION OF CYANIDATION TAILS AND …
O 2 + H 2 SO 4 → H 2 SO 5 + H 2 O (4) The "hot" process yields 25 - 45% Caro's acid, whilst a "cold" process yields 70 - 80% (1). Due to its instability, Caro's acid is produced on-site and used immediately for cyanide detoxification with only minimal or no storage. The reaction of Caro's acid with cyanide (and WAD cyanides ...
