Aqua Regia Gold Recovery | Gold Recovery | Gold Refining with Aqua Regia/How to refine gold with Aqua Regia

Those who want to learn the gold recovery process from e-waste extensively use the keywords how to recover gold from aqua regia. This is because most people have the conception that the aqua regia process is the only and  best method to extract gold from e-waste. There are many other methods to remove gold from e-waste, and aqua regia is one of them. The economic viability and easy availability of the material or chemicals used in the gold recovery process are the first considerations when choosing a method to remove gold from e-waste.

Undoubtedly, the aqua regia method is an easy gold recovery process. To prepare aqua regia, you need to mix one part of nitric acid and three parts of hydrochloric acid. These acids are very corrosive and produce toxic fumes. So, while mixing them, you should be careful to avoid splashes, as they might cause burns. In case you happen to have some splashes on your body, you should immediately wash them with plain water.

Jewellers normally use aqua regia to get their gold from old jewellery, scrap jewellery pieces, filings, jewellery bench work, etc. One kilogramme of scrap jewellery can be digested by 3.5 to 4.5 litres of aqua regia. You can use Teflon plastic or glass for the aqua regia gold recovery method. First, gold scrap should be placed in the digesting pot, and then aqua regia should be poured onto it slowly and carefully. The scrap metal begins to dissolve into the aqua regia. The aqua regia is poured until the whole metal is dissolved. Once the metal undergoes digestion, we filter the solution. If only gold metal is present in the filtered solution, the colour of the solution is yellowish; if other metals such as copper, nickel, etc. are mixed in the solution, the colour of the solution is green. We should neutralise the excess nitric acid in the solution to ensure the easy and complete precipitation of gold. It is either done by boiling the solution to almost dryness or by adding some chemical that neutralises the nitric acid.

By now, you have only half the answer to how to recover gold from Aqua Regia. Precipitating a hundred percent gold from the gold chloride solution is not as easy as it sounds. Many precautions are taken to ensure the complete recovery of gold from the aqua regia solution, and the correct choice of the gold-reducing chemical is also a very important part of this gold recovery process. Occasionally, for various reasons, some particles of other metals may also settle to the bottom with the gold dust. To ensure the maximum purity of gold, it may be necessary to repeat the entire process.

Gold from CPUs Processors/Gold Extraction from Processors/Gold Recovery from Chips/How recycle Chips Processors

From one kilogramme of CPU (386 and 486), we get 6 to 6.5 grammes of gold. Everyone desires a CPU, including you and me. CPUs have gold wires inside them. It is very easy to recover gold from the CPU. You can make it your part-time or full-time business, too. When we consider gathering CPUs in large quantities, it may seem daunting, but it's actually not that difficult. In India, the e-scrap business is a very organised trade. We have a great number of scrap dealers in every city, and these scrap dealers have contacts in big companies from where they lift large quantities of e-scrap, and each scrap dealer is associated with numerous mobile scrap collectors who go door to door or shop to shop to collect e-waste. And, this way, these wholesale scrap dealers have great quantities of e-scrap. And you may purchase just about any kind of e-waste item from them.

If you want to recycle gold from CPUs and make it your part-time or full-time business, I can assure you that it is profitable. You need a 50-square-foot area of land or at least a 20-foot x 20-foot properly ventilated room.

The basic requirements of equipment for this business are some plastic tubs, one water storage tank, one small furnace, one blower, one exhaust fan, one large heat-resistant glass bottle, two pairs of medium- and full-size gloves, one hammer, a pair of tongs, two or three different types of pliers, cutters, files, a gas stove, etc.
As for chemicals, you can use either aqua regia or the cupellation process. The Aqua Regia method is more preferable. Old CPUs have a golden cap on them, but the latest CPUs don’t have a golden cap. You must cut or break them into small pieces so that the chemicals can reach inside and react with gold. To prepare aqua regia, you have to take one part of nitric acid (HNO3) and three parts of hydrochloric acid (HCL). Prepare the solution according to the requirements. Don’t make too much of it. Place the CPUs in the plastic tub and start putting aqua regia on them gradually.

Aqua regia will start the reaction with the metals in the CPUs and produce toxic fumes. So, don't stand too close to the tub. When the reaction slows down, see if the metals have dissolved fully into the solution. If the metal is left, add more aqua regia to the solution and keep pouring the acids slowly till the metals are completely digested. This reaction turns gold into gold chloride. Now we need to separate the remains of the CPUs from the solution and wash them with plain water two to three times to remove gold chloride from them. Mix this water with the solution, and filter this solution through a filter paper.

To achieve 100% gold recovery, it is crucial to carefully and patiently remove the gold from the solution. For this, you may contact us either by phone or through the mail.

 

Gold Recovery from Chips/How to Recover Gold from Chips/Gold Extraction from Chips

People think that gold recovery is limited to computer chips only. Every electronic device has a motherboard, and that motherboard has some chips mounted on it. It could be a DVD, a mobile device, or just any electronic device. We get gold from all the chips. Gold is an essential part of a chip. It takes the form of very thin wires inside a chip. Undoubtedly, extracting gold from chips is a very profitable business. I receive numerous calls every day, and most of the people ask me how to recover gold from computer chips. Before starting the business of gold recovery from chips, we must have the correct knowledge of the precious metal content of one pound or kilo of chips or integrated circuits so that we can make the right purchase. Well, we can’t obtain the same quantity of gold from all the chips. There are many factors behind it. Chip manufacturing companies used a lot of gold at the early stage of chip manufacturing because, at that time, gold was very cheap. As gold became more and more expensive, chip manufacturing companies reduced the quantity of gold in them. But certain chip manufacturers maintained their standards, and they did not reduce the quantity of gold so heavily. But they had to sell their chips at higher prices. We get a comparatively lesser quantity of gold from chips made in China.

Now, the question is: how do you recover gold from computer chips? Well, it is not so easy. Many companies have made a big investment in installing very expensive machinery to extract gold from chips and other precious metals from different types of e-waste. The first and foremost thing is not to pollute the environment when you remove gold from chips. Pyrolysis and hydrometallurgy are used to extract gold from chips. Chips are first incinerated and crushed into a fine powder, and then mixed metals are either melted or treated chemically to separate gold from them.

In India, some people are engaged in gold extraction from chips in a manner that is not environmentally friendly. In the open air, they simply burn chips. They are unaware that this type of electronic scrap burning produces toxic fumes. Poor people engaged in this kind of work are not at all aware of what kind of health risks they are exposing themselves to. So, my advice to those who want to start this business is to have proper knowledge about it so that they can take sufficient precautionary measures.

Since obtaining gold from chips is a very profitable business, a lot of people all over the world are interested in starting this business, either on a small or large scale. These days, there are numerous videos on the net telling people how to get gold from chips. But they forget one thing: the use of chemicals without proper guidance can also be hazardous. I am not trying to scare anybody unnecessarily or discourage people from doing this business, but the fact of the matter is that it is always safe to have a trained teacher guide us at the initial stage of a business, especially one of this nature.

We have developed some safe, environmentally friendly methods of gold extraction from different kinds of e-waste. And we are always ready to provide solutions to your problems regarding gold

How to earn money fast and easy from e-waste/Instant Money from E-waste/How to Start E-waste Business

For quite some time, people have been suggesting numerous ways of making fast and easy money on the internet while living in the comforts of their homes. And this has been going on even before the internet existed. The money-making gurus have mastered this skill so well that they easily convince you to buy their techniques for becoming rich soon. They start by claiming to be your best well-wishers and unique examples of humanity. But ultimately, the whole episode leads to their selling books, CDs, etc. to you. Whether you make money through their suggestions or not, they certainly do.

But I would be very straightforward here, right from the beginning, without creating any background for it. I am telling you this because I also want to make money when you do. If you fully understand and then start what I am going to tell you in a very short time, I can assure you that you can undoubtedly make fast and easy money beyond your imagination. You see, every day, the e-scrap generates like anything in every part of the world now. And most people have become conscious enough to get rid of it as soon as possible. So, you can make fast and easy money through the e-waste business.

Here is how: You can start it by making a free website or a blog to collect e-waste from people in your city. There is a very good way to collect e-waste free of charge. But you must be honest. You must first decide that a particular share of your income will go to charity. And you should say the same thing to people on your website: that by giving their e-waste to you free of charge, they will be able to help the needy people of society.

You can either do it alone or form a group of like-minded people on a profit-sharing basis belonging to different parts of the city. Make a proper strategy so that all the group members can collect e-waste from their neighbourhoods as well as from certain other areas conveniently. You will soon start receiving calls from people interested in donating their electronic waste. The strange thing about e-waste is that, until some time ago, people identified it with computers only. But now people have a better understanding of it. They know that the scrap of any electronic device is e-waste. Be it computers, cell phones, TVs, calculators, etc.

Once you start receiving e-waste, you can change a room in your house into a dismantling unit. Dismantling e-waste is not a big deal. There are many videos available on YouTube about how to dismantle a computer or TV, etc., so you can watch some videos for that. And the tools required for dismantling are quite affordable, too.
There are many recycling plants that always want to buy e-waste. And you can easily sell your e-scrap to them. But, Beware! Recycling companies don’t pay you much for the scrap. The fact is that their profit margins are quite large. This is a secret that only a few people know. So, to make the maximum profit out of it, what you have to do is don’t sell them everything. You can easily recover gold, silver, and palladium from certain items.

Those items are golden fingers, gold-plated connectors, gold-plated printed circuit boards, processors and chips, etc. We can also help you recover precious metals from computer parts or from any other kind of e-waste.

It is very easy to dismantle hard drives and power supplies. On hard drives, you get gold-plated connectors and logic cards that have gold-bearing chips on them. You also get Multilayer Ceramic Capacitors (MLCCS) from logic cards. These MLCCS are a good source of palladium, silver, etc. On hard drives, you also get aluminium, magnets, bearings, motors, and platinum-coated platters. Platters are not worth trying. Since the recovery cost of platinum is greater than the amount of platinum that you get from platters, you can sell such items to recycling companies.
The positive side of this business is that it is a metal business, and all the metals sell for cash. Additionally, this business does not experience any issues with dead stock. So, this is the business that allows you to make money easily and quickly.
