The Dangerous Process of Melting Old Phones Into Pure Gold | Backyard Refinery

[00:00:00]Have you ever wondered where those old broken phones go after they're thrown away? Today, let's sneak into a manual recycling workshop to see how they turn tech trash into pure gold. First, thousands of legendary brick phones are gathered and stripped down.

[00:00:17]Workers remove the cases, extract the batteries, and keep the most valuable part, the circuit boards. These boards contain an incredible amount of precious metals.

[00:00:30]Watching this next part will definitely shock you.

[00:00:37]>> Instead of using modern machinery, they mix these circuit boards with dot dot dot dried cow dung cakes.

[00:00:46]This primitive method creates a unique burning environment to easily separate plastic from the metals.

[00:00:54]It might look strange, but it is a highly effective traditional technique.

[00:01:06]>> The entire mixture is piled up into a massive mount and then they light it up.

[00:01:12]The fierce flames quickly burn away all the organic impurities and plastic coatings, leaving behind the raw metallic components, ready for the next stage.

[00:01:28]Once the fire dies down, the ash and slack containing the raw metals are raked out.

[00:01:34]It looks like nothing more than a pile of worthless dirt, but the real treasure is hidden right inside.

[00:01:42]Every single grain of this ash is carefully gathered so not a single bit of metal is wasted.

[00:01:50]This slag is fed into a specialized crushing machine to be ground into a fine powder.

[00:01:58]After that, the craftsman mix this powder with various chemical fluxes right on the ground.

[00:02:06]This crucial step prepares the metals to melt smoothly at a later stage.

[00:02:14]The thorough blending ensures that all impurities will separate cleanly during the upcoming melt.

[00:02:24]The well-mixed powder is packed into large sacks and transported over to the furnace area.

[00:02:31]By this time, the furnace has been preheated and stoked, ready for the ultimate step.

[00:02:40]The intense heat radiating from the core shows just how extreme this process is.

[00:02:51]The metal powder is poured directly into the glowing red hot coal furnace.

[00:02:57]At thousands of degrees C, everything melts down completely, creating a fiery red liquid that looks just like mesmerizing glowing lava.

[00:03:13]It is a fascinating yet incredibly intense sight to behold up close.

[00:03:21]Finally, the molten metal is poured into earthn molds to cool down.

[00:03:32]Shiny metal blocks gradually reveal themselves after the outer layer of slag is chipped away.

[00:03:44]A recycling process that is crude, dangerous, yet full of the raw ingenuity of these craftsmen.

[00:03:55]As soon as the raw metal blocks from the tech trash cool down, they are taken straight to another wood-fired furnace, they are liquefied once again at extreme temperatures to squeeze out remaining impurities.

[00:04:13]When the molten metal reaches the perfect consistency, dot dot dot, the craftsman carefully skims off the dark layer of slag floating on the surface.

[00:04:26]Now the pure core metal is poured into a large earth and pond mold forming a flat circular metal disc that looks incredibly solid.

[00:04:46]This scorching hot metal plate is immediately dropped into a bucket of cold water to cool down.

[00:04:55]Look closely. The water instantly turns a beautiful emerald green color.

[00:05:03]Dot dot dot. Due to the chemical reaction of hydrated copper compounds, this green water is then decanted into large storage containers.

[00:05:21]Next is the extraction phase where they separate the valuable substances from the waste.

[00:05:29]Specialized filter sheets are used to catch the fine dark gray sludge settling at the bottom.

[00:05:38]Don't look down on this dark mud that looks like ordinary swamp dirt.

[00:05:47]dot dot dot because this is exactly where the highest concentration of gold and silver is hidden.

[00:05:57]This precious powder residue is washed repeatedly with clean water and chemical solutions.

[00:06:06]Dot dot dot to completely eliminate any remaining lightweight impurities.

[00:06:16]The more thoroughly it is washed, the higher the ultimate purity of the precious metal will be.

[00:06:24]>> And here comes the absolute pinnacle of chemical refining.

[00:06:32]>> The clean fine powder is poured into a large heatresistant beaker filled with concentrated acid.

[00:06:44]The mixture is stirred continuously until it transitions into a brilliant honey-like golden liquid.

[00:06:56]This liquid solution is then placed onto a gas stove to be boiled directly.

[00:07:07]The craftsman even uses bare hands to stir the boiling chemical mixture, which is incredibly hazardous.

[00:07:18]Once the perfect temperature is reached, pure gold crystals begin to precipitate.

[00:07:28]dot dot dot suspending in the liquid to create a mesmerizing, highly valuable golden glow.

[00:07:41]An unbelievable process from broken phones to pure gold.

[00:08:01]Hey everyone, welcome back to my channel.

[00:08:09]Today I'm taking you to explore an amazing traditional glass recycling workshop.

[00:08:25]Have you ever wondered where old glass bottles go?

[00:08:37]Let's find out together in today's video.

[00:08:48]The first step is sorting. The workers meticulously sift through the broken glass.

[00:08:59]Purity is crucial to ensure the quality of recycled.

[00:09:11]After that, they gather the glasses back and wash them in large water tanks. It's really hard work.

[00:09:26]And here is my favorite part, the furnace. The glass is melted at an extremely high temperature.

[00:09:39]It looks like molten lava. It's truly overflowing standing this close.

[00:09:52]>> With the skilled hands of a craftsman, each drop of liquid glass is placed into the mold.

[00:10:14]In just a few seconds, beautiful little bottles start to take shape.

[00:10:25]Fresh products born from broken char.

[00:10:27]Their creativity is truly impressive.

[00:10:48]Finally, each product is carefully inspected and packed in boxes.

[00:11:18]So from discarded fragments, they are reborn into useful items once again.
