"Inside digital cameras—especially older ones—you’ll find a CCD sensor, the brain that captures images.

 And guess what? It has a tiny bit of gold!"

 "See these thin golden wires? They connect the chip to the circuit board! And yes, they’re real gold—because gold is super good at conducting electricity and doesn’t rust!"

 "BUT… before you start smashing cameras for treasure, hold on. There’s barely a few milligrams of gold in each one… that’s like finding one noodle in a whole pot of soup!"

 "To get a gram of gold, you’d need hundreds of these sensors. That’s a lot of old cameras!"

 "So unless you're a tech recycler with tons of these, don’t quit your day job just yet!"

 "But hey, next time you see an old camera, you can say, ‘That thing’s got gold in it!’ And sound super smart. 😆"

Gold wire from IC chip by boiling with sulfuric acid

ChatGPT พูดว่า:

Extracting gold wire from an IC (integrated circuit) chip using boiling sulfuric acid is a dangerous process that requires extreme caution. Sulfuric acid at high temperatures can cause severe burns, toxic fumes, and violent reactions if not handled properly.

Overview of the Process

Gold wires inside IC chips are usually bonding wires that connect the semiconductor die to the chip's leads. These wires are extremely thin (usually 99.99% pure gold) and embedded in resin or epoxy. Boiling sulfuric acid can dissolve the epoxy and expose the gold wires.

Materials Needed

IC chips (from CPUs, RAM, old circuit boards, etc.)

Concentrated sulfuric acid (H₂SO₄, 98%) – highly corrosive!

Heat-resistant glassware or ceramic crucible

Hot plate or controlled heating source (not open flame)

Fume hood or outdoor well-ventilated area

Personal protective equipment (PPE):

Acid-resistant gloves

Face shield & goggles

Respirator (for acid fumes)

Chemical-resistant apron

Procedure

Preparation:

Ensure the work area is well-ventilated (preferably under a fume hood).

Wear all safety gear before handling sulfuric acid.

Heating the Sulfuric Acid:

Pour concentrated sulfuric acid into a heat-resistant container.

Slowly heat the acid on a hot plate (NOT an open flame) to ~200–300°C.

WARNING: Boiling sulfuric acid releases sulfur dioxide (SO₂) and sulfur trioxide (SO₃), which are highly toxic!

Adding IC Chips:

Drop the IC chips slowly into the hot acid.

The acid will dissolve organic materials (epoxy, resin, plastic, etc.), leaving behind gold bonding wires.

Gold Recovery:

Once the process is complete, carefully remove the gold wires using tweezers or filter the solution through a fine mesh.

Neutralize any remaining acid using sodium bicarbonate (baking soda) slowly.

Rinsing and Refining:

Wash the gold wires with distilled water and isopropyl alcohol to remove acid residues.

Further refine the gold if needed.

Safety Precautions

Do NOT use glass beakers unless they are high-temperature resistant. Sulfuric acid at high temperatures can cause thermal shock and break glass.

NEVER add water to sulfuric acid! Always add acid to water if dilution is necessary.

Handle acid fumes carefully. Prolonged exposure can cause lung damage.

Dispose of waste properly. Neutralize used acid before disposal.

Alternative Methods

Aqua Regia (HNO₃ + HCl) can dissolve gold, which can then be precipitated.

Nitric acid can dissolve base metals, leaving gold behind.

Incineration (burning off plastic in a controlled environment) can expose gold wires.

Gold wire from IC (integrated circuit) chips is an ultra-thin, high-purity gold wire used for bonding semiconductor components. It connects the silicon chip to the lead frame, allowing electrical signals to pass between the chip and the circuit board. This process, called wire bonding, is crucial in microelectronics due to gold's excellent conductivity, corrosion resistance, and reliability. However, due to high costs, manufacturers sometimes replace gold with copper or silver. Recovering gold from IC chips is a common practice in e-waste recycling, where the chips are processed to extract and refine the gold.

**Gold wire from IC (integrated circuit) chips** is a fine, high-purity gold wire used in **wire bonding** to connect semiconductor chips to their packaging.

Gold Rush: The Socket Pin Edition

Characters:

• Dave – A DIY enthusiast who thinks he's a gold mining expert.
• Lisa – His skeptical but supportive friend.
• The Narrator – A dramatic voiceover that makes everything sound more intense.

---

[Scene: A cluttered garage filled with old electronic parts. Dave stands proudly with a bucket of socket pins.]

Narrator: In a world where treasure is hidden in the most unexpected places... one man dares to seek it!

Lisa: (crossing arms) So let me get this straight—you think you're gonna get rich from these tiny, crusty socket pins?

Dave: (grinning) Not just rich, Lisa. Filthy rich! Do you know how much gold is in old electronics? Tons! Well, like… micrograms, but still!

Lisa: (rolling eyes) Right. So what’s the plan? Melt them with a hairdryer and hope for the best?

Dave: (scoffing) Oh, ye of little faith! I have a scientific process. First, we use acid to dissolve the base metals, then we extract the pure gold flakes, and finally, we forge our own jewelry empire!

Narrator: The road to riches is paved with… potentially hazardous chemicals and bad decisions!

Lisa: (grabbing the bottle of acid) This says, "WARNING: Highly dangerous! Do not inhale, touch, or think about too hard." Are you sure you know what you're doing?

Dave: (hesitating) Well… I watched a bunch of YouTube videos. That counts as expertise, right?

Lisa: (deadpan) Yeah, like watching cooking shows makes me a five-star chef.

[Cut to: Dave wearing an oversized lab coat, ski goggles, and oven mitts, ready to pour acid into a beaker.]

Narrator: And so, the alchemist begins his work…

Lisa: (ducking behind a table) This is how supervillains are made, Dave.

[Dave carefully pours acid. The mixture starts bubbling ominously.]

Dave: (nervous chuckle) That’s… probably normal.

Narrator: But then, a plot twist!

**[The beaker starts foaming over. A small spark flies out.]

Lisa: (panicking) Probably?! Dave, I’m not trying to grow an extra eyeball today!

Dave: Relax, it’s just a chemical reaction. (pause) Probably.

[Suddenly, a tiny speck of gold emerges from the foam.]

Lisa: (grabbing a magnifying glass) Wait… is that actual gold?!

Dave: (beaming) I TOLD YOU! I AM A GOLD MINER!

Narrator: Against all odds, our hero has struck gold… approximately 0.0001 grams of it!

Lisa: (calculating) So if we process about a thousand more socket pins, we might afford a cup of coffee.

Dave: (thinking) …Okay, new plan. We start a YouTube channel about extracting gold!

Narrator: And thus, an empire is born. Or at least, a very, very weird hobby.

[Scene fades out as Dave and Lisa start brainstorming ridiculous video ideas.]

Hello friends

Normally, gold extraction usually has chemicals left over from gold extraction, which is usually water, which will contain gold.

Today, I have a technique for separating gold from chemicals left over from gold extraction. We will use electricity to extract gold from the remaining chemical water.

You should make the chemical basic first, the pH should be at or near 7.

We will use electricity to pull the metals in the water to stick to the plate.

When we have the metal that is stuck to the plate, use nitric acid to dissolve the metal. There will be a small amount of gold and metals that nitric acid cannot dissolve. At this stage, we may need to extract

 the remaining gold with aqua Regia again to make it more pure.

Extracting gold using electricity is typically done through a process called **electrowinning** or **electrorefining**. Here are two common methods:  

### 1. **Electrowinning (Electroextraction)**  

- Used in gold mining operations to extract gold from a cyanide or acid leach solution.  

- Gold ions in solution are plated onto a cathode (usually made of stainless steel or carbon) using an electric current.  

- The process is efficient and commonly used in gold recovery from low-grade ores.  

### 2. **Electrorefining**  

- Used to purify gold after initial extraction.  

- The impure gold is made the **anode**, and a pure gold sheet is the **cathode** in an electrolyte solution.  

- When electricity is applied, pure gold ions move to the cathode, while impurities settle as anode sludge.  

These methods require electricity, chemicals, and careful control to ensure efficiency and safety.
