This document provides a general overview of the use of cyanide in the gold and silver recovery process, and is not intended to be a technical reference on the use of cyanide to recover these metals.
The cyanidation process for the extraction of gold and silver from ore has been employed since 1898 when it was first used in New Zealand and Africa and soon after in the United States. It is a very efficient process capable of extracting gold in amounts of less than one percent of an ounce from a ton of rock with over 90% efficiency.

cyanide process: Method of extracting silver and gold from their ores by dissolving them in a dilute solution of sodium cyanide or potassium cyanide.
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.
