How to Recover Gold from Cell phones/Gold Extraction Method from Mobile Phones/Gold Recovery from Mobile Phones

The cell phone has become an essential thing in our lives today. We seem to be incomplete without cell phones. And it is a plus for the e-waste recyclers. There is a great variation in the yields of precious metals from cell phones of different makes. I mean, you don’t get the same amount of precious metals from all the cell phones. Branded mobile phones give you better gold recovery than the cheaper ones, especially those made in China. If you dismantle a cell phone, you will find the gold on its motherboard (PCB). The connectors in cell phones are gold-plated. The chips on the mobile motherboard also contain gold.

Before recovering gold from the cell phones, you have to dismantle them. The ceramic capacitors in cell phones contain silver, gold, palladium, and sometimes platinum. So, first of all, remove all the components from the motherboards carefully. There are many videos on YouTube that explain the dismantling of cell phones. You can watch one or two videos and understand the whole process.

First, we will talk about gold recovery from mobile PCBs. These days, there are many non-cyanide gold recovery chemical compounds with different brand names available on the market. You can search for them on the internet and buy one. They are very economical, and most of them are made in China. Their brochures provide you with complete details about how to use the chemicals for gold recovery. So, you can use that chemical to recover gold from mobile PCBs. Another option is cyanide gold recovery. But cyanide is harmful. If you need some help with it, You can write to me as well.

Secondly, we need to recover gold from gold-plated connectors used in mobile phones. You can use nitric acid to do so. Gold recovery from gold-plated pins through nitric acid is also a good process. However, you should do it in an open place or in an appropriately ventilated room.

Thirdly, you have to process chips for gold recovery. Chips are first burned and then ground into a fine powder. Then the pins are separated from the powder or ash through a sieve. Store these pins, and when you have a saleable quantity of them, you can sell them to a smelter.

The fine ash contains the very thin gold wires used in bonding in the integrated circuits. So, using a metal bowl, you can wash away all the ash with water. This technique is referred to as panning. There are many companies that sell these panning bowls. They show you a demo as well. It is not very expensive. You can get it at an affordable price. After removing the ash, you have silicon chips and golden wires left in the bowl. With aqua regia, you can recycle that gold.

Apart from chips, there are other components on the motherboard that contain gold. Aqua regia can also treat these components to recover gold.

I have intentionally kept the article short. Mentioning all the details about gold recovery processes would make the article too long. Some people might find a long article boring. So, I have given the basic ideas about the processes mentioned above. You can always write to me if you need to know more about any of the processes mentioned in the article.

Is there any future for e-waste recycling in India / E-waste Recycling Business / E-waste Recycling Plant

E-waste recycling undoubtedly holds a great future in India. But you have to streamline this trade. Last year, 1.85 million tonnes of e-waste were generated in India.

We are all increasingly addicted to a variety of electronic devices. So, obviously, every year the quantity of e-waste in India is going to be even greater. India is marching towards prosperity at a faster pace. And this has given the Indian consumer a great deal of power to buy good brands of mobiles and laptops, etc. Expensive brands use more precious metals in their gadgets. As a result, recycling companies make more money when they recycle precious metals from them.

A metal recycling company recycles electronic scrap. The metal business has many advantages; it is a cash business. Any metal sells like hot cakes. Iron is the cheapest metal compared to copper, aluminium, etc.; you can even sell this metal any time on the phone. The reason being that every metal finds so many uses that its demand never decreases. There could be a little timely fluctuation in the prices sometimes, but it does not affect the demand much. These factors, plus many more, make people opt for e-waste recycling businesses in India.

All the big companies just want to get rid of e-waste because they want their place to be clean. That’s why they dispose of their e-waste either at a very low price or free of charge. Some of the workers in the big firms are very careless. They throw away the computer or just any other electronic device, even with the slightest fault. And the recyclers benefit greatly from this practice. When the recyclers pick up CPUs or monitors from big companies, they segregate them and have those machines tested and refurbished. Around 30 to 40 percent of the of the material, be it computers, mobile phones, or just any other e-scrap, becomes functional with a slight repair. In this way, recyclers generate significant profits. And this will never stop.

Another important thing that goes in favour of the licensed recyclers is that the government has made a law that only licensed recyclers can pick up the material now because 80% of e-waste in India is processed in he illegal or unauthorized  sector. And the people in the unauthorised sector don’t use any machines to process it. They simply burn large piles of it in the open, resulting in a lot of pollution. Until sometime back, it was a big problem for the authorised e-waste recyclers because they had tough competition with the small-scale illegal sector recyclers. But now, the government of India is very strict about pollution issues. It is coming down very hard on the unauthorised sector. A lot of the raids are conducted in the illegal sector; unbilled materials worth hundreds of millions of rupees are seized every month. Severe penalties are imposed. And this works in favor of the registered recyclers. Because all these strict measures are taking the e-waste recycling industry towards an opportunity that registered recyclers have long been waiting for. So, there is definitely a good future for e-waste recycling in India in an environmentally friendly manner.
