"With stricter limits globally being imposed on cyanide discharge levels in plant tailings, having a reliable and well designed cyanide detoxification circuit is critical for any operation. The INCO SO2/Air method is most commonly used for cyanide detoxification where sulfur dioxide and oxygen combine to oxidize cyanide to the much less toxic cyanate. This …

In fact, it is so slow that complete destruction of all cyanide by chlorination at high pH is not possible in a flow-through system. By lowering the pH below 10, the ionization of cyanides increases and the activity of the chlorine accelerates, resulting in more efficient cyanide and cyanate destruction. In other words, at pH values above 10 ...
