Prior to 1900, mining technology had used the cyanide process, a method whereby gold or silver could be more easily separated from low grade ores, or those with a low percentage of valuable metals. Simply stated, the cyanidation process involved treating finely crushed gold bearing ores with solutions of sodium or potassium cyanide.
