The gold should slip down into the smelting vessel After this occurs you can cool and remove the gold from the smelting vessel and also remove the slag as well Its common at this point to refine the gold through a separate refinement process to ensure a high level of purityFurther Details

Separation of copper from gold mixture A discussion started in 2004 but continuing through 2017 2004 Q Dear I am a student in University of Sulaimany in Iraq I have a question please show me a way for separation copper from gold and I mixed gold with copper I want to separate the two metals by any chemical methods Please help meFurther Details
React the mixture with H2SO4 because copper is more reactive and a mettalic oxide so it would displace H2 from H2SO4 which would escape out in form of gas and CuSO4 would form Then mix the mixtureFurther Details

Feb 24 2013 · was351 Depending on gold to silver ratio content of the metal the silver in aqua regia can make it hard to dissolve the gold as the silver chloride forms a crust keeping the acids from dissolving the gold and then also the gold can make it hard for nitric acid to get at the silver to remove the silver copper from the goldFurther Details
Smelting which results in nearly pure gold involves melting the negative terminals in a furnace at about 2100 degrees F 1149 degrees C When workers add a chemical mixture known as flux to the molten material the gold separates from the metal used to make the terminals Workers pour off the flux and then the goldFurther Details
These foils are about 80 gold and copper 20 In order to reach a higher level of purity a second bath is required For that we will need to create a test Chemical called Stannous cloride or Sn CL2 This metal is essential for Identify how much gold is left in our 2nd chemical bathFurther Details
In this Instructable I will show you how to extract gold from computers using products most people have lying around in their homes The way I extract the gold is relatively straightforward and pretty easy but the chemicals used are very dangerous and should not be performed without proper knowledge and equipment This process is not supposed to be lucrativeFurther Details
