» Drywashing for Gold
Fine pieces of gold, while not magnetic, do tend to be attracted to surfaces which have been electrostaticallycharged, similar to the way iron particles are attracted to a magnet. So the bottom matting in these concentrators often attract fine particles gold to itself and tends to hold them there. Some motorized dry concentrators also use a highfrequency vibrating device to keep the entire ...
