Ask The Experts - How do I recover gold in pyrite?

It is not easy to get the gold out of that pyrite—there is no simple and easy method. The best answer as to how to recover that gold depends on the amount of pyrite you intend to process. If you have only a few pounds, it can be roasted by heat in the open air and then mixed with a flux like sodium borate and melted with a collector metal like copper.It is not easy to get the gold out of that pyrite—there is no simple and easy method.
