Jul 27, 2016· In plant practice, the solution strength for gold approximates 0.05 per cent NaCN, or 1 lb. cyanide per ton solution. Stronger solutions do not seem to hasten the dissolution or improve the extraction, and as the chemical and mechanical loss of cyanide is much higher with strong solutions, obviously it is desirable to hold the solution at the …
