The process of separating gold from sand mainly consists of four steps: crushing and screening, removing slime from gold sand, separation, thickening and dewatering stage. Step #1: Crush and Screen the Sand. Most of the alluvial gold contain cemented mud, which is attached to the gravel or pebbles. If it is not broken in advance, it will cause ...

The Old Copper Complex in North America has been radiometrically dated to 9500 BP—i.e., about 7480 BCE—making it one of the oldest known examples of copper extraction in the world. The earliest evidence of cold-hammering of native copper comes from the excavation at Çayönü Tepesi in eastern Anatolia, which dates between 7200 to 6600 BCE. Among the various items considered to be votive ...

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 the gold will now be alloyed in the copper.
