Did you Know?


SILVER

Over 95% of the silver produced in a year is used in photography, jewelry and silverware, and industrial products

Kodak and Fuji companies are the world's largest consumers of silver

Silver is effective in treating burns by killing bacteria, allowing the burn to heal more quickly pure silver has the highest electrical and thermal conductivity of all metal.

The main producers of silver are the United States, Mexico and South America

GOLD

Gold was made into art objects and jewelry as far back as 4000 BC

Alchemists, the forerunners of today's chemists, attempted  to turn base metal into gold

Gold does not tarnish, rust or corrode

One cubic foot of gold weighs more than half a ton

The main producers of gold are South Africa, the United States, Australia, China, Canada, and Russia

PLATINUM 

Platinum is the rarest of all precious metals

Approximately 10 tons of raw ore have to be mined to produce one pure ounce of platinum

The main producers of platinum are the former Soviet Republics, South Africa, and Canada

All the platinum ever mined would fill a cube less than 25 feet on each side

Scarce metals, such as platinum, face depletion risks this century because of the lack of suitable substances in such devices as catalytic converters and hydrogen fuel cells.
