- The U.S. is increasingly reliant on supply of mineral raw materials from other countries.
- Advanced technologies are increasingly making use of nearly the entire periodic table of the elements.
- Dynamic studies of critical and strategic mineral supply and demand can identify emerging potential supply risks.
How much gold has been found in the world?
About 244,000 metric tons of gold has been discovered to date (187,000 metric tons historically produced plus current underground reserves of 57,000 metric tons). Most of that gold has come from just three countries: China, Australia, and South Africa. The United States ranked fourth in gold production in 2016.
All of the gold discovered thus far would fit in a cube that is 23 meters wide on every side.
Most of the gold that is fabricated today goes into the manufacture of jewelry, but gold is also an essential industrial metal that performs critical functions in computers, communications equipment, spacecraft, jet aircraft engines, and a host of other products.

What is "Fool's Gold?"
Fool's Gold can be one of three minerals. The most common mineral mistaken for gold is pyrite. Chalcopyrite may also appear gold-like, and weathered mica can mimic gold as well. Compared to actual gold, these minerals will flake, powder, or crumble when poked with a metal point, whereas gold will gouge or indent like soft lead. In addition, actual gold will leave a golden yellow streak when...
What is the meaning of the karat mark on gold jewelry?
The fineness of jewelry gold is stated as the number of parts in twenty-four that are gold. Thus, 24 karat gold is pure gold; 12 K would be an alloy that is half gold and half copper or other metals.
What is white gold?
White gold was originally developed to imitate platinum (a naturally white metal). White gold is usually an alloy containing about 75% gold and about 25% nickel and zinc. If stamped 18 karat , it would be 75% pure gold.
How much silver has been found in the world?
Of the 1,740,000 metric tons of silver discovered to date, 55% is found in just four countries on earth. All the silver discovered thus far would fit in a cube 55 meters on a side. Learn more: USGS commodity website for silver
What is sterling silver?
Sterling silver is the standard of quality for articles containing 92.5% silver and 7.5% copper (and/or other alloys).
How much copper has been found in the world?
To date, roughly 700 million metric tons of copper have been produced around the world. This would fit into a cube measuring about 430 meters on a side. Identified deposits contain an estimated 2.1 billion metric tons of additional copper, which brings the total amount of discovered copper to 2.8 billion metric tons. This would fit into a cube measuring 680 meters on a side. It is also estimated...
How do we extract minerals?
The primary methods used to extract minerals from the ground are: Underground mining Surface (open pit) mining Placer mining The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use. Higher-grade metallic ores found in veins deep under the Earth’s...
How large is a lifetime supply of minerals for the average person?
At today's level of consumption, the average newborn infant will need a lifetime supply of: 871 pounds of lead 502 pounds of zinc 950 pounds of copper 2,692 pounds of aluminum 21,645 pounds of iron ore 11,614 pounds of clays 30,091 pounds of salt 1,420,000 pounds of stone, sand, gravel, and cement Learn more: Mineral Resources: Out of the ground...into our daily lives
How many pounds of minerals are required by the average person in a year?
To maintain our standard of living, each person in the United States requires over 40,630 pounds of minerals each year: 10, 765 pounds of stone 7,254 pounds of sand and gravel 685 pounds of cement 148 pounds of clays 383 pounds of salt 275 pounds of iron ore 168 pounds of phosphate rock 35 pounds of soda ash 34 pounds of aluminum 12 pounds of copper 11 pounds of lead 6 pounds of zinc 5 pounds of...
