When final sample (72 hours usually) has been taken, the residual cyanide must be determined. Procedure for this determination is outlined elsewhere. Wash solids with warm water and dry, setting aside for final residue. Comments on this Cyanide Gold Extraction Process/Method:

What is cyanide and why do we need cyanide-free gold leaching process? Cyanide (CN –) has been used since 1889 to recover gold from hard rock. As sodium cyanide (NaCN), it reacts with gold, oxygen (O), and water (H 2 O) to form a gold cyanide complex (Na [Au(CN) 2] ) and sodium hydroxide (NaOH). The chemical reaction dubbed …
