All language subtitles for 20260104 How Is Silver Made？ [History of Simple Things]

[music]

Welcome back to History of Simple

Things. Today's topic comes from one of

our viewers, Hamzat Galag. [music]

Thanks for the great suggestion. You

asked, "How is silver made and where

does it actually come from? [music]

Whether it's in your grandmother's old

tea set, a shiny coin in your pocket, or

the circuitry of your phone, silver is

everywhere. But this gleaming metal

doesn't start out looking anything like

the polished [music] pieces we see in

daily life. It begins its story deep

underground, hidden inside ordinary

looking rock. [music]

So, how does raw, gritty ore transform

into one of the most iconic and valuable

metals in human history? Stick around as

we dig into the incredible journey of

silver [music]

right here on History of Simple Things.

Silver is a naturally occurring element

[music] represented by the symbol AG on

the periodic table and it's found in the

Earth's crust, but it rarely shows up in

its pure form. Most of the time, silver

is extracted from other ores. minerals

like galina, which is primarily lead

sulfide, but often holds silver deep

within. Other times, it can be found

alongside copper, gold, or zinc. In

fact, much of the silver we use isn't

even mined specifically for silver. It's

produced as a byproduct during the

extraction of these other metals.

To get to it, miners use open pit or

underground mining techniques depending

on where the deposits are located. If

the silver ore is closer to the surface,

giant earthmoving machines strip away

the overburden, the soil and rock

covering the deposit [music] and haul

out tons of ore. In deeper deposits,

miners may use tunnels or shafts to

reach the silver rich rock. But either

way, once the ore is out of the ground,

it doesn't exactly sparkle. [music] At

this point, it's just a heavy grayish

mix of rock that requires some serious

chemistry to become usable silver.

Once extracted, the silverbearing ore

underos a kind of mechanical makeover.

First, it gets crushed, literally. Giant

jaw crushers or cone crushers reduce

massive rocks into smaller chunks. Then

it's ground into an even finer powder

using ballmills where rotating steel

balls pulverize the material to the

consistency of flour. This isn't just

for convenience. It's all about

increasing the surface area. The finer

the particles, [music] the more

effectively silver can be separated from

the surrounding waste rock.

After grinding, what remains is called

slurry, a mixture of finely ground ore

and water. It's from this slurry that

silver begins to separate from

everything else. But here's where things

start to get a little more technical and

magical.

Next up is the flotation process.

Especially common when silver is found

with other metals like lead or copper.

The slurry is mixed with chemicals and

air is blown through it. What happens is

quite clever. Those chemicals cause the

silver and other valuable minerals to

become hydrophobic, meaning they repel

water and cling to bubbles. As the

bubbles rise, they carry the silver rich

minerals to the surface, forming a

frothy layer. This layer is then skimmed

off and dried. What's left behind is a

silver concentrate, a far richer version

of the original ore.

Now, it's still not pure silver. This

concentrate often contains a mix of

silver, other [music] metals, and

impurities. So, it's time for the real

purification to begin.

Smelting is where fire meets rock. The

silver concentrate is placed in a

furnace and subjected to extremely high

temperatures, often above 1,000° C. At

this heat, the metal melts and separates

based on density. Silver, being heavier

than many impurities, sinks to the

bottom. Slag, the lighter waste

material, floats to the top and is

removed.

If lead was present in the original ore,

it may be used to collect silver during

smelting. [music] This method known as

cupupilation dates back to ancient

times. The lead absorbs the silver and

once it's all melted together, the

mixture is placed in a special porous

dish called a pupil. When reheated, the

lead oxidizes and gets absorbed into the

pupil, leaving behind metallic silver.

At this stage, the silver is still not

pure enough for fine applications, but

it's a recognizable metal now, shiny and

soft, just waiting to be refined even

further.

To achieve the high levels of purity

required for electronics, jewelry, or

investment grade bullion, silver goes

through electrolytic refining. Think of

it as using electricity to polish the

silver at a molecular level. In this

method, impure silver is used as the

anode while a thin sheet of pure silver

acts as the cathode. Both are immersed

in a bath of silver nitrate solution and

an electrical current is passed through.

Over time, silver from the end node

dissolves into the solution and

redeposits onto the cathode as pure

silver. Impurities like gold and

platinum drop to the bottom as a sludge

known as a node slime which is collected

and processed separately often for

valuable byproducts.

After refining the final product is

99.9%

pure silver sometimes called 3 9 fine.

This is the same grade used in fine

silverware, investment coins and

high-end electronics.

Once refined, silver is usually cast

into large bars or ingots for storage or

sale. These ingots can later be remelted

and fabricated into virtually anything

from thin wires for electronics to

sheets for solar panels to intricate

shapes for jewelry.

Silver might seem old-fashioned,

especially in a world dominated by

digital everything, but it's anything

but obsolete. In fact, silver is more

relevant than ever. Beyond its use in

jewelry, and table wear, it's found in

smartphones, solar panels, electrical

contacts, medical devices, and even

water purification systems. Its

antimicrobial properties make it useful

in wound dressings and hospital

equipment. And of course, it still

carries economic value. Silver bullion

and coins remain popular among

investors.

So the next time you see a silver ring

or spend a silver coin, you'll know

there's more to that shimmer than meets

the eye. There's an entire story behind

it. A story of digging, crushing,

refining, and molding. A story of

science, tradition, and craftsmanship.

Silver doesn't just appear. It's made

through human effort and ingenuity,

shaped over centuries by techniques that

continue to evolve even today. It's a

quiet reminder that even the most common

objects often have incredible journeys

behind them. [music] and silver. It's

one of the best examples we have of

beauty born from beneath our feet.
