There are several problems that fine and ultra-fine particles can cause depending on the process. In gold leaching operations they can cause carbon fouling or interfere with Merrill-Crowe. Fines are notorious for being difficult to selectively float as well as degrading the selective flotation of coarser particles when they are intermixed.

Q. I am retired and am a recreational prospector with a small (3 in.) suction dredge and a creek with a little gold worth messing with. Some of the gold is so fine it is floater and I figure there is maybe an economical way to capture this like a revolving screen barrel with an electrolysis setup of some kind to attract the fine gold and maybe adhere to the screen.

The more gold, the faster the process. This is because it is the friction of gold against gold which facilitates the cleaning process. Once the gold is glittery, rinse the soapy water out of the jar, pour the gold into a small (metal) finishing pan, and heat it up (outside and down wind) until the gold takes on a deep, natural, shiny luster.
