The secret of the gold production process is guarded so much that in order to get inside the factory and take pictures, the operators of Radio Wrocław had to undergo an hour-long procedure of security control at the entrance to the plant. Any devices that record sound and photograph the image are unacceptable.

This is where gold and silver are produced from copper waste. From the "black mud", that is from the anode slime, extremely valuable precious metals are obtained here. In addition to gold and silver, palladium, platinum and technical selenium are smelted.
