This question is often answered by East African miners by actually engaging into gold cyanidation business. Some of them are winning, majority of them are loosing fortunes, and even if making it profitable, they are still loosing a lot of gold while endangering environment, animals, fish and crops around them. In the program Start Your Own Gold Mine we are not using any cyanidation methods.
