If one has to use cyanide process for gold extraction, never use laboratory grade always use commercial grade and use sodium cyanide instead of potassium cyanide that is less risky. I have seen gold electroplaters gold plating jewelry or doing reverse plating using sodium cyanide of commercial grade. It works wonders if handled properly.
