Extract gold from scraps electronic items
1) Collect any gold-containing metal scraps to which you have access, including jewelry, computer processors, old telephone wiring or gold tooth crowns. Keep in mind that outdated electronics items are produce enough gold.

2) For scrap metal choose correct size of container, jar and chemicals. In which you wish to refined. You need container capacity 300 milliliters, 30 milliliters nitric acid, and 120 milliliters of hydrochloric acid for every ounce of scrap gold metal.

3) Apply all safety gear correctly before working with any chemicals. The acids involved in this process are highly corrosive and react strongly.

4) Add your scrap materials and the appropriate amount of nitric acid, as mentioned above, to the smaller of your plastic containers. Wait 30 minutes before adding the hydrochloric acid. Let the chemical reaction develop overnight to be sure that all of the gold has dissolved.
5) Filter the particles out of the acid in the plastic container by attaching a Buckner funnel filter and pouring the remaining liquid into the larger of the plastic containers. The resulting acid will be deep green and translucent.

6) Create a urea and water solution boiling a quart of water and combining it with one pound of urea Pour this mixture into the acid slowly. until no chemical reaction can be observed. This process raises the pH levels of the acid, there is eliminating the nitric acid.

7) Heat a quart of water. and add the sodium bisulfite to the boiling water in the ratio of one ounce of sodium bisulfite for every ounce of metal being refined. Pour this mixture slowly into the acid and wait for a reaction.

8) Observe the muddy separation. that collects at the bottom of the acid container. This substance is pure gold. Extract the gold from the container. using a filter.
Substance three time filter with clean water. and The result will nearly 100 percent gold.

Tips & Warnings
1) Some experts recommend using SubZero in place of nitric acid. This nitric acid replacement reacts in lower quantities and does not create as many fumes.
2) Do not attempt this process if you do not have adequate chemistry lab experience.
