Gold in eWaste

Global Scale

Electronic waste has a lot of gold inside. In 2022, people made about 53.6 million metric tons of e-waste. Experts say this waste had over $91 billion in valuable metals. ذهب was a big part of that value. By 2030, the world could make 74.7 million metric tons of e-waste. This fast growth means more ذهب will be thrown away in old electronics.

The United Nations Environment Programme says up to 7% of the world’s yearly ذهب supply is now in e-waste. This number shows how much ذهب people toss out each year. Most of this ذهب is not recovered because only a small amount of e-waste is recycled.

ملحوظة: One ton of e-waste can have up to 75 pounds of ذهب. This makes e-waste one of the richest places to find ذهب today.

By Country

Countries make different amounts of e-waste and recover ذهب at different rates. The United States makes the most e-waste. In 2022, the US made enough e-waste to get about 13,767 kilograms of ذهب. China and India also make a lot of e-waste and have lots of ذهب in it.

The United Kingdom is working to get more ذهب from e-waste. The UK Royal Mint started a program to take ذهب from old electronics. This plan wants to get hundreds of kilograms of ذهب each year and show other countries what to do.

Compared to Ore

E-waste has much more ذهب than mined ore. Studies show e-waste has about 10 times more ذهب than regular gold ore. على سبيل المثال, e-waste can have 10 ل 10,000 grams of ذهب in each ton. Mined ore has much less ذهب per ton.

This high amount makes e-waste a great place to get ذهب. Getting ذهب from e-waste uses less energy and hurts the environment less than mining. Many experts think recycling e-waste is a better way to get the world’s ذهب.

نصيحة: Recycling ذهب from e-waste saves resources and helps stop harmful mining.

Why Electronics Use Gold

Key Properties

Gold is a favorite for making electronic parts. Engineers pick gold for many good reasons:

• ذهب lets electricity move fast and easily. This helps circuits work well.

• Gold does not rust or get damaged by air. Devices last longer because gold stays the same, even in tough places.

• Gold is soft and easy to shape. Makers can turn it into thin wires or sheets. This is important for building small circuits.

• Gold sticks well to other things like copper and silicon. This helps devices work well for a long time.

• Gold does not change when it touches air or water. It keeps shining and working, so it is great for important parts.

• Gold’s softness helps make smaller and stronger electronics.

ملحوظة: Gold’s mix of being a good conductor, lasting a long time, and being easy to bend makes it very important in many high-tech uses.

Devices with Most Gold

Some electronics have more gold than others. These devices need strong and lasting connections. The devices below usually have the most gold:

• Computers and laptops, mostly in motherboards, CPUs, and connectors

• Smartphones and old mobile phones

• VCRs and other video machines

• Sound systems and audio gear

• Semiconductors in many smart devices

Gold is found in gold-plated contacts, connectors, and tiny wires inside these items. Each device has only a little gold, but it adds up fast when many are thrown away.

نصيحة: Recycling these devices can get back a lot of gold. This means less new mining and helps protect the environment.

eWaste Recycling Challenges

Collection Issues

Getting e-waste for gold recovery is hard. Workers often take apart devices by hand. This job takes a lot of time and work. Taking out circuit-board parts and batteries needs care. Printed circuit boards have metals and plastics mixed together. This makes it hard to separate them. Factories use many steps to sort the materials. They crush, use gravity, and other methods to help. Treating the mixed stuff from these steps is also tough.

Unsafe recycling can hurt people and nature. Burning plastics outside lets out bad fumes. Small businesses cannot match big factories. They also have trouble using safer chemicals. E-waste is growing fast because devices do not last long. This puts more stress on collection and recycling.

نصيحة: Safe and smart collection helps get more gold. It also keeps workers and nature safe.

Awareness Gaps

Knowing about e-waste is very important. Many people do not know what e-waste is. They also do not know how to recycle it. More than half of people do not know how recycling works. Most people have never recycled their electronics. Many keep old devices at home instead of recycling. Some worry about their data being stolen.

When people learn e-waste is valuable, they recycle more. Ads and rewards like gift cards can help. If people know and get rewards, most will recycle. Good collection and recycling save gold and other materials. This means less mining and helps the planet.

Regulatory Barriers

Laws decide how e-waste is collected and recycled. Weak rules let unsafe recycling happen. Illegal groups may not follow safety rules. This can cause pollution and make people sick. Hard rules can slow down good recycling companies. They may have to pay more or wait longer to follow the law.

Clear and fair rules make eWaste Recycling safer and better. Good checks make sure recyclers use safe ways. This protects people and the earth.

eWaste Recycling Methods

Chemical-Free Innovations

New ways without chemicals are changing how companies get ذهب from electronic waste. Laser ablation is a top method. It uses strong laser pulses to turn ذهب on parts into vapor. The laser can change the size and shape of ذهب bits by changing its settings. This way is fast and does not use bad chemicals. It also keeps other stuff safe from harm. Many experts think laser ablation is cheap and good for the planet.

Flinders University found another new way. Their team uses a safe compound called trichloroisocyanuric acid with salt water to dissolve ذهب from e-waste. A special polymer with lots of sulfur grabs the ذهب. This polymer can be used many times. The process does not use dangerous chemicals like mercury or cyanide. It works even when there is only a little ذهب. Early tests show it gets a lot of ذهب and picks it out well. Bigger tests are planned, and this way looks safer and better for getting ذهب.

ملحوظة: Chemical-free ways help keep workers and nature safe. They also make eWaste Recycling better for companies and people.

Biological Approaches

Biological ways use living things to get ذهب from e-waste. These ways are greener than old methods.

• Microbial bioleaching uses bacteria like Acidithiobacillus و Pseudomonas to turn solid ذهب into a form that can be collected. These bacteria break down metals using acidolysis and redoxolysis.

• Companies such as Mintek use special bacteria in big tanks to get ذهب from hard materials. They now make similar systems for e-waste.

• Mint Innovation mixes chemical and biological steps. أولاً, they use chemicals to remove base metals. ثم, they use Cupriavidus metallidurans bacteria to take in ذهب ions. This works in small test plants.

• Scientists use genetic engineering to help bacteria make more cyanide. This helps get more ذهب by making it easier to dissolve.

• Teams often use groups of different bacteria. Each kind works best on certain metals, so more ذهب is recovered.

• Researchers change things like pH and particle size to help bacteria work better. They also train bacteria to handle the toxic parts of e-waste.

These biological ways are growing fast. They give a safer and greener path for eWaste Recycling.

XRF محلل Role

تحليلات XRF are important in today’s e-waste recycling. These small devices use X-rays to find metals in scrap. When X-rays hit a sample, the atoms give off special energy signals. The analyzer reads these signals to tell what metals are there, يحب ذهب, فضة, and platinum.

Recyclers use XRF analyzers to sort and grade metals fast. This helps them find the best parts and separate them from less valuable ones. The process does not hurt the materials. XRF analyzers also help find dangerous stuff, making recycling safer for people and nature.

نصيحة: Sorting fast and well with XRF analyzers helps get more ذهب. It also helps companies follow safety and green rules.
