Refining gold from ore or concentrates is done during the smelting process. During this process, flux is used to dissolve contaminates such as metal oxides from the gold. The flux is added to a crucible with the gold that is then melted in a furnace. You can make flux for gold refining by first obtaining all of the ingredients and then mixing them together in the proper portions.

and into the anode (positive electrode), completing the electrical circuit. The current causes the gold to plate out onto the steel wool cathodes. Upon the completion of an electrowinning batch, the cathodes are removed from the cell for calcining and smelting. Calcining involves prolonged heating of the cathodes at 750°C, the purpose being to oxidise the impurities (iron, copper etc) that

metals from wires and circuit boards, glass from monitors, and plastics from casings (fig. 1). For example, 1 metric ton (t) of electronic scrap from personal computers (PC's) contains more gold than that recovered from 17 t of gold ore.1 In 1998, the amount of gold recovered from electronic scrap in the United States was equivalent to that recovered from more than 2 million metric tons (Mt

31.03.2020· Generally, you can get at least a little bit of gold out of anything that contains a circuit board, with additional gold found in elements like connective pins. Computers and televisions tend to be the electronics with the most gold in them, but camcorders, media players, game consoles, and cell phones also contain gold.

The answer relates to the properties of the metals. Gold is used in electronics because it is more inert, ductile and malleable than copper. A few days ago, while buying a new hard disk for my laptop, I noticed that certain parts of it were plated with a gold-colored metal.It made me curious about whether the metal was actually gold or not.

28.03.2017· Gold, silver, platinum and palladium can all be recovered from circuits and processors of electronics. Of all the precious metals, gold is the one most frequently recovered and refined from electronics. Although it is possible to melt the gold plating away from the circuitry, you will cause more of a mess and lose some of the precious metal. The most effective way to reclaim gold from scrap
