how to separate gold from aluminum

How to separate gold from other metals like silver ,Gold Smelting

How do I separate gold from other metals like silver, aluminum etc? This can only be done by refining the alloy Normally it would be sent to a refiner, as the materials needed are dangerous (eg, acids) and you would have to know quite a bit of chemistry to do it safely as well as effectivelyGold Smelting : Professional mining companies recover gold and other precious metals in quantities sufficient enough to pay refiners to do the smelting for them But what can smaller scale recreational gold miners do? , Detailed directions are given for use of fire-assay techniques to separate and concentrate the noble metals Ag, Au, Ir, Os.

Use a magnet to separate magnetic metal (ferrous) from non-magnetic metal (non-ferrous) Sort your ferrous metal into tin, lead, and steel Sort your non-ferrous metal into copper, brass, gold, and aluminum Then within your buckets of all individual metals, sort by cleanlinessSeparation processes are an important part of the aluminum manufacturing process The three basic processes used in making aluminum are the Bayer process, for the conversion of bauxite into alumina, the Hall-Heroult process, for the electrolytic smelting of alumina to aluminum, and the alloying, casting, forging, and fabrication processes for making products.

Extracting a metal from its ore

Metals with low chemical activity, such a gold and silver are normally found in their pure state Copper, tin, lead, and iron are more reactive and must be heated with carbon to extract the metals Aluminum, calcium, sodium and other active metals are extracted using electrolysis Copper can be extracted from its ores by reductionAug 03, I am new to refining have an recently disemboweled a cell phone and have ended up with many gold-plated contacts and pins I don't have the means to use chemicals neither do I want to, but I can melt gold I am wondering how to separate the gold plating from these pins/contacts effectively without using chemicals How is this possible? Thanks!.
