🙏 Miners feel their difficult work produces something precious

Q & A

How deep underground do the miners go?
-The miners go 112 meters underground, which is as deep as a 30-story building.
What makes finding gold difficult in the mines?
-Gold exists as small particles mixed in with rock, not as pure nuggets, so it's hard to locate.
Why did Japan conceal some gold veins during their occupation?
-To hide riches from Koreans and extract more gold later after regaining control of the mines.
What makes the drilling work dangerous?
-The hard quartzite rock can damage drilling equipment and falling debris from drilling threatens workers.
How much gold is typically extracted from the processed ore?
-From 70 tons of processed gold ore, only about 1 ton of pure gold is extracted.
Why add various chemicals during gold smelting?
-Chemicals like borax help collect gold particles together into one mass and remove impurities.
What gives the workers pride and meaning in their job?
-Discovering Korean gold that can contribute to the national economy gives them pride in this difficult work.
How does the geography aid in gold formation?
-Cracks in granite let rising magma carry gold deposits upwards, concentrating the gold in veins.
Why is rail work important in the mines?
-Straight, gapless rails allow safe transit of heavy materials in the narrow tunnels.
What advancements have helped with drilling?
-Electric detonators and dynamite allow safer, more controlled blasting than older manual techniques.
