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 straight-forward and pretty easy, but the chemicals used are very dangerous and should not be performed without proper knowledge and equipment.Get A Quote
This process is not supposed to be lucrative. It is a great science project. So dont try to make money off of this process. You will end up losing moneyAlso, please remember if you like this Instructable, please vote for me. I work very hard and spend a lot of time to make these Instructables. It would truly mean a lot. Thanks and Enjoy.
Although this method of gold extraction calls for household chemicals, that doesnt mean they are safe. Please be advised that you must handle these chemicals with care. Goggles, gloves, glass apparatus and a very well ventilated room with a fume hood and a gas maskrespirator are needed as well or an outside area is highly recommended.
After this experiment is over, I will show you how to properly dispose of the chemicals. You should know before starting this experiment, you must set up an appointment with a haardous waste processing facility or H-MRF.
Sep 23, 2017nbsp018332Electrostatic concentration occurs because the high-velocity air flowing through the unit creates an electrical charge which attracts and holds gold to the riffle tray cloth like a magnet. The same airflow then holds the material in suspension allowing the heavier materials to sink into the riffles where it.
If you have any question regarding the safety of this experiment, please ask me through comments or a PM before performing any of this experiment.
And last but not least, the chemicals1 Toilet Bowl Cleaner must contain hydrochloric acid. If you have lab grade hydrochloric acid, by all means use it. Can be found at Home Depot, most home improvement stores and plumbing supply stores. HAZARDOUS do not ingest or get in eyes and mucous membranes.

Computers and other electronic devices contain gold and other precious metals in their circuit boards. As consumers upgrade their electronic gadgets, the precious metals remain trapped in piles of waste. Theres about 0.2 grams 0.007 ounces of gold in a typical mobile phone handset. Recovery of this gold requires knowledge of basic chemistry and considerable care.
Assemble the scrap circuit boards from computers or phones, memory chips from phones and cameras, and the small components behind LCD screens. Gold in these circuits occurs as a layer over a base metal substrate such as nickel or copper. Separate the gold-plated metal parts in the circuit boards using a magnet. Some gold-plated parts may be inside ceramic components.
Put on the goggles and gloves. Place all of the recovered circuit parts in one of the glass containers. Use another glass container to mix hydrochloric acid and hydrogen peroxide in the proportion 2 to 1. Pour the mixture over the circuit board scrap in the glass vessel. Leave for a week, stirring occasionally with the plastic rod. The acid will turn into a dark solution. The gold will slowly flake from the scrap and accumulate at the bottom of the container.
Separate the gold flakes from the solution by pouring it through a coffee filter. Allow the solution to drip through to a third glass beaker. The gold flakes will remain on the filter. Fill the plastic tray with water to half of its depth, place the remaining circuit board scrap in it and rinse. Pour this water through the filter to extract any remaining gold flakes.
Flush water over the gold flakes to wash them. Pour the methanol through the filter to wash the gold flakes. Wash the flakes again by pouring water over them. Leave the gold flakes to dry on the filter paper.
Put on the overalls and boots. Use the blowtorch to heat up the crucible or clay bowl you are using to melt the gold flakes. Place a teaspoon of borax powder into the bowl and continue heating until it begins to place. Add the gold flakes at this point. Continue heating until the gold flakes melt to form a bead. Cool the crucible and its contents. Use the metal prod to chip out the gold from the solid borax.

Gold Extraction Gravity Separation. Gold ore extraction electrostatic separation methods gold extraction and recovery processes semantic scholar various methods such as gravity concentration flotation panning common method used in the leaching of gold from the ore amalgam and then the separation of the gold.
The goal of this study was to assess the sustainability of a modified cellulose nanofiber material for the recovery of precious gold from chloride solution, with a special focus on gold recovery from acidic solutions generated by cupric and ferric chloride leaching processes.
2014-6-19ensp0183enspThe Merrill-Crowe or Cementation process is used for concentration and purification of gold and silver from cyanide solutions. Among other available options for recovery of precious metals from cyanide solutions, Electrocoagulation EC is a very promising electrochemical technique for the recovery of this precious metals.
Nov 21, 2018nbsp018332Many artisanal and small-scale miners are achieving high rates of gold recovery without mercury, benefiting their health, the health of their communities, and the environment. On this page, we summarie some of the techniques in mercury-free artisanal and small-scale gold mining.

Have some scrap gold laying around Have you recently scored some gold dust or small nuggets on a recent creek panning adventure If so you might be happy to know that you can actually melt it at home. This article will show you how to smelt melt gold at home using nothing more than an old 1200 watt microwave. Sounds strange right Not really people are doing it every day. If you are safe and follow directions you can do it too. It beats the old method of melting gold with a propane torch.
Gold has long been valued for currency, as well as being desired for beautiful jewelry. For centuries, gold has been one of the most pried metals found in the earth. The more pure the gold, the more valuable it is. The process of smelting is how gold is separated from impurities, with the end result being solid gold.
It is possible to melt your own gold, with the proper equipment. If doing small amounts, like melting down broken jewelry, it is possible to even use a 1200 watt microwave to do the job. It is best for the microwave to not have the magnetron on the top of the unit, but rather either the side or back. It is also important to make sure that once you start using a microwave for working with the gold, it should no longer be used for food preparation.
By using a specially designed ceramic kiln, and following the safety guidelines, you will be melting downyour own gold nuggets in no time. Before beginning, make sure to wear eye protection, a dust mask, gloves, and long sleeves. Tongs are another important piece of equipment, to allow the safe handling of the crucible. It is also a good idea to work in a well ventilated area.
