Champlain Scrap Make Money Scrapping Metal & Gold Recovery

Updated on April 24, 2016

What should you do when you pickup or get items to scrap

The first thing you should always do is check on Google or eBay to see if other are selling what you have. See if anyone is selling broken ones. Maybe see if parts from the model you have are value and sell them that way.

If you don't find that they have any value, you should scrap them. Separate all the metals and if you're into gold recover, keep all the gold material. Keep in mind scrap is the lowest value you will get for an item and you would need a lot to make it worth your trip to the scrap yard. I usually fill up my mini van and usually get a$300 to $400 out of a trip

Aqua Regia Warning Use at your Own Discretion

WARNING: Chlorine (Cl2), nitric oxide (NO), and nitrogen dioxide (NO2) are poisonous!

The gas evolution will lead to pressure build-up and container rupture if the container is closed.

Preparation and Safe Handling

  • Appropriate Personal Protective Equipment (lab coat, safety glasses, with side shields or splash goggles and gloves compatible with nitric and hydrochloric acid) should always be used when handling aqua regia.When handling large amounts (>500mL) or when splashing is more likely, wear acid resistant gloves with extended cuffs. Check the manufacturer's rating for hydrochloric and nitric acid.
  • All handling of aqua regia MUST be done with glassware inside a fume hood. Never remove a container with aqua regia from the fume hood. Keep the sash as low as possible to capture the toxic fumes. Never raise it above the indicated position (18 inches).
  • Perform all work in a secondary container that is clean and free of organic matter.
    Warning: NEVER add any organics to aqua regia solution, it could cause an explosion. Any chemical containing a C-H bond, e.g., acetone, isopropanol, ethanol, photoresist, detergents, is organic. Even small amounts of organics could make the aqua regia solution unstable.
  • For best results and for safety reasons, make only small, fresh batches of aqua regia for each use.
  • When preparing aqua regia, always add nitric acid to hydrochloric acid, never vice versa.

Emergency Procedures

Accidental Exposure

Skin Contact

Rinse the affected skin immediately with copious amounts of water for about 15 minutes; if necessary, use the safety shower. Remove contaminated clothing.

Eye Contact

Use the eye wash to rinse the eye thoroughly for at least 15 minutes, occasionally lifting the upper and lower eyelids and rolling the eyeballs.

Inhalation

Move into fresh air immediately.

Ingestion

Do not induce vomiting. Rinse mouth with water.

If any symptoms persist after the first aid procedures, seek medical attention. Provide the medical team with the Safety Data Sheets (SDS) for hydrochloric acid and nitric acid.

Spills

Spills should be neutralized immediately with sodium bicarbonate or other acid neutralizer.

Storage

WARNING! Never store a stoppered bottle of aqua regia—it may explode! Aqua regia should be made fresh before every use and excess amounts neutralized shortly after use.

Disposal

Pour excess and waste aqua regia into a large quantity of ice (500 grams of ice per 100 mL of aqua regia). Neutralize the mixture with an aqueous basic solution, such as 1M or 10% sodium hydroxide (NaOH) or saturated sodium bicarbonate (NaHCO3) in water until pH is neutral. The neutralized solution may then be poured down drain. If the neutralized mixture contains heavy metals (e.g., gold, platinum, lead, chromium), the solution should be labeled and disposed of through the chemical waste management system. Fill out a Request for Pickup of Chemical Waste (CWM-TRK-01).

  • Aqua regia (with barium, cadmium, lead & selenium waste) – UI# 80574
  • Aqua regia (with chromium waste) – UI# 80575
  • Aqua regia (with all other wastes) – UI# 586

Gold Recovery Process

Please read the article above for Safety because Aqua regia is made up of acids that could be dangerous. I'm just providing some information on how this is done but I'm in no way a specialist and trying this is at your own discretion.

There are many different processes for gold recovery. This is the simplest process compared to other hazardous chemicals. Here we go…
Step 1
Cut the parts of the circuit boards that contain gold and put them in the bucket & throw away the other parts of the board. If you also have CPU chips hot them with a hammer as the gold parts are usually inside the chip. Place these in the bucket too.
Step 2
Take a clean 5 gallon bucket and either use aqua regia (nitric acid and hydrochloric acid) In the ratio 1:3. Remember to use gloves these are very hazardous materials.
Step 3
Place your CPU chips and cut up boards in a plastic wire mesh basket and then place this in the solution. The metal should start to fizz and give off a brown fume. (these fumes are toxic so make sure you are doing this process with an adequate mask or in an open area!) This chemical reaction is the gold dissolving into the acid solution, this process can take up to 2 hours so leave the boards in the solution for a while. Come back in 2 hours and check the boards to see that all the gold has been dissolved.
Step 4
The gold is now dissolved into the acid solution. This acid is reusable until there is no longer a chemical reaction of fizzing and fuming. Once the acid liquid is no longer reacting and dissolving the boards then remove the basket and check the liquid to see if any lumps of other material still remain in the liquid. If there are then filter this liquid or simply decant it into another container leaving the solid lumps behind.
Step 5
Your acid liquid should be a dark green clear liquid, if it looks cloudy or there are bits floating in it then you need to decant it or filter it until it is clear. Once its done then add some urea to the acid liquid little by little. It should react by fizzing - keep on adding the urea until the liquid does not fizz anymore.
Step 6
Once it has stopped fizzing you need to add precipitant to the acid liquid to extract the pure gold. You need roughly 1.5 spoonfuls of precipitant (Sodium Bisulfite (Na2HSO3) for every ounce of metal dissolved so remember to roughly weigh what you dissolved in the first place. Add the precipitant to a clean bucket and then add the acid solution. The precipitant and the acid will react forming a muddy solution that should sink to the bottom. This mud is your pure gold! To know whether you have extracted all the gold from the acid liquid - test some of the acid for gold content - using a gold detection liquid - if there is any gold in the acid still the gold detection liquid will turn purple brown. If there is still gold in the acid then add more precipitant.
Step 7
The acid should now be a clear green or amber color with mud sunk to the bottom. Pour off the acid into another container leaving only the mud. When the acid has been poured off add 2 or 3 gallons of water to the mud then pour off the water making sure you dont pour off any of the mud. The rinsing ensures the high purity of the gold. Test the mud with aqua ammonia for the purity of the gold. If it turns blue then you need to keep rinsing. Give a final rinse with distilled water.
Step 8
Once you are sure of the purity of the gold then you have your mud or powder. You can melt the powder and you will then have your pure gold.
