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

cyanide process or cyanidation, method for extracting gold from its ore. The ore is first finely ground and may be concentrated by flotation if it contains certain impurities, it may be roasted. It is then mixed with a dilute solution of sodium cyanide or potassium or calcium cyanide while air is bubbled through it.read more

Cyanide process is also called as Macarthur-forest Process. It is the process of extracting gold or silver from the ores by dissolving in a dilute solution of potassium cyanide or sodium cyanide. This process was introduced in the year 1887 by the Scottish chemists naming Robert W. Forrest, John S. MacArthur, and William Forrest.read more
