Peace to all! i have an idea in mind that gold tailings from a ballmill can be extracted by other method like AR bath of tailings..... i have an aprox. 400 grams of tailings/soil, dried and then bathed in AR....mixed it and let the AR work, after a few hours and some of the solid settled, i was very excited to see yellow/orange fluid on top of the sludge, i siphoned it and put some …
Using peracetic acid (Vinegar 5% & H2O2 3%) electrolyte to strip a silverplate dish. The solution came from the other silverplate stripping, that was used after electrolysis to get the slimes into solution. Turns out copper acetate is percipitating the copper as the reaction occurs.

Fine gold particles can be recovered in other concentration devices such as flotation and/or leaching. SAG mill circuit. Gold Recovery. Gold recovery comprises similar stages to the processing of most ores. First, the valuable minerals are separated from the gangue through concentration.
Gold extraction can do several methods. In each method depends on material that you use for extraction. In case, We use electricity; it's an easy method that you can do it alone. Silt gold extraction is suitable for plated gold …
Traditional gold extraction involves several steps: crushing, leaching, adsorption, desorption, electrodeposition, and purification. Sodium cyanide is used to leach gold into a soluble complex. Activated carbon (AC) adsorbs this complex, and the gold is then recovered through stripping and electrolysis [1, 2]. AC losses occur due to attrition ...
