1. Removal of nitric acid: Add urea until no more visible reaction (fizzing stops)
2. Precipitation of Gold: Add ferrous sulfate. This causes the gold chloride to "reduce" to gold, yielding a cloudy solution ready for filtering.
3. Filtration: Allow precipitation to occur for as long as possible (1 night here). Siphon and filter gold. Clean and cast.
Answer
Not very easily! I don't know of any ways... Presumably you'd want to either use a precipitation reaction or an electrochemical method, but in both cases I don't know of any reagents that wouldn't get destroyed by the aqua regia themselves in the process.
Answer
Or you can just place a piece of metal higher in the reactivity series than gold (that's just about every metal) in the solution and the gold will come out.

Can water be used to separate salt from sugar why or why not?
A mixture of salt and sugar can be separated by using an organic solvent to dissolve the sugar. When the sugar is dissolved, it can be separated by filtering the salt from the liquid sugar,then recrystallise both solutions to from back their original crystals.
After dissolving gold in aqua ragia how to get back gold?
Well i have read that if you are desolving unpure gold i.e. 14k then you first add salt a bit at a time to precipitate silver, filter the silver solids and then add Sodium Hydroxide or sodium sulphate (Lye) a bit at a time until all gold is precipitated. filter out the gold solids (black dust) then kill the mixture with Lime juice for safe disposal.
Can you separet gold from aqua regia with k2s2o5?
Yes, it is possible to separate gold from aqua regia using potassium disulfite (K2S2O5). When K2S2O5 is added to aqua regia, it can reduce gold ions back to metallic gold, precipitating it out of solution. This process is often used in gold refining to recover gold from the aqua regia solution after it has dissolved the metal. However, proper safety precautions should be taken, as aqua regia is highly corrosive and toxic.
Is Aqua regia a mixture or compound?
Mixture of hydrochloric acid and nitric acid, latin means "royal water" because it disolves gold
How would you separate dissolved sugar from water?
By evaporating the water out, which precipitates the sugar back into its crystalline form.

What should you use to separate sand and sugar?
Dissolve it it water and filter it through paper. The sand will be in the paper and then sugar will be dissolved in the water. You can let the water evaporate and you will have the sugar back.
