Hello Gold refining forum ! i have 3 containers of solution with sludge i let set to the bottom. Now i know im gonna get schooled in this forum because there are some bright minds in here and im an amateur at this ! so i took a pyrex dish set 2 heavy duty beakers inside the pyrex dish, and filled them half way with my gold plated, and karat scrap items but mostly pins from different kinds of electronic devices, and i poored about one cup of hydrochloric acid in each beaker then i slowly added a half cup of nitric acid in both beakers let it cook for about 15 minutes or untill i seen there was no more gold on the pins. I processed about 12 pounds of pins. Then after that i poored the stripped pins out of the beakers into the pyrex dish and diluted it with filtered water.Then i took some tongs and grabbed the pins bunch by bunch and rinsing then off in another pyrex dish with water in it. Then i poored the solution into the containers you see in the pics, and let it settle for a couple days. Now i figured i would carefully scoop the water off with a ladle but now what do i do with my sludge ? and the picture with the red lines on it can someone please tell me what those 4 different layers in the sludge are ?
