<p>A method for removing cyanide from an aqueous stream is disclosed, wherein: the aqueous stream (such as a tail stream from a carbon in leach (CIL) mining operation) is contacted with activated carbon in particulate form under conditions wherein the Eh (oxygen reduction potential (ORP) measured in mV) of the aqueous stream is from 0 - 300 mV, to remove cyanide from the stream; or the aqueous stream is treated to control the Eh to from 0 - 300 mV, and thereafter the aqueous stream is contacted with carbon to remove cyanide from the stream.</p> |
