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. The melt can be poured into a mold and ...

· Re: Ag/Auextracting from pyrites (no rosting/no NaCN) Roasting the pyrite to drive off the sulfur does one thing. The pyrite then becomes magnetic and can be easily separated by magnetic means. I use to do this all the time. Then a little sulfuric acid with digest the iron, leaving any gold/silver behind.
Based upon numerous case studies, it appears that gold particles in pyrite are generally fine, ranging from 75 microns down to 2 or 3 microns. The incidence of fine gold's quantity also appears to be related to the gold concentration, as well. If the assay is 2 ounces per ton, there are generally larger gold particles present along with the typically fine micron sized gold. When the grade ...

· The safest way to extract gold from rocks at home is to crush the rocks. However, you might use mercury to extract the gold if you're able to obtain some, though this is dangerous. While both mercury and cyanide can be used to extract gold from rock, it's hazardous to both your health and the environment to use them. Steps. Method 1. Method 1 of 2: Crushing Rocks to Extract Gold.
Separating fine gold particles from black sands is one of the biggest challenges that gold prospectors have to deal with. This article will describe a simple and inexpensive method of capturing fine gold. Most small scale prospectors do not need to invest thousands of dollars to capture small placer gold dust. Using fine gold recovery methods, you can retain the vast majority of gold in your ...
