Mining

Portugal is the leading European producer of tin.

There is really no reason to drill for oil in Antarctica -- it's physically challenging and too expensive because it's a polar climate, and the Antarctic Treaty forbids commercial extraction from any location south of 60 degrees south latitude anywhere on earth.

over 100,000 people were killed in the mines

Calcite (CaCO3).

Mining, Forestry, etc .

France does mine for minerals. Some of them are:

1. gold 2. silver 3. talc 3. tungsten 4. bromine

It is found in New Jersey [Franklin], Tennessee, Illinois, and other states of the U.S.; Mexico, Germany, India, England, and other parts of the world. I found this on: "http://library.thinkquest.org/05aug/00461/calcite.htm"

foliated rocks, defined as "metamorphic rocks with parralel layers or "bands". three examples of these foliated rocks are gneiss, slate, and schist. three examples of foliated rocks are schist, gneiss, and schist.

Common minerals that are found in Antarctica are antimony, chromium, copper, gold, lead, molybdenum, tin, uranium and zinc. There are also large deposits of coal and sedimentary iron found in some Antarctic areas.

Maybe you mean element instead of mineral? If that's the case, knife steel is composed of a variety of elements to achieve specific characteristics for the knife. Some common elements in quality cutlery steel are:

-chromium

-molybdenum

-vanadium

-manganese

-carbon

other elements are used as well but these are just a few of the "core" elements that are more commonly found. As an example, steel with a higher carbon content will be tougher and less prone to chipping however it will corrode faster than a more "stainless" steel. If you have a blade with a high nitrogen content, the knife will be very resistant to corrosion but may not be quite as tough.

Indiana is most known for farming, and their most popular crops are corn and soy beans, but they also grow large quantities of wheat, tomatoes, and pumpkins.

Indiana's state tree is the tulip tree, and there are many types of oaks and maples popular there too.

Central Indiana also has coal and oil deposits, however these haven't been tapped into much. Recently, ethanol plants have sprung up around Indiana because of the discovery of turning corn products into an alternative source of fuel.

It can be found almost everywhere in soil and rock, in rivers and oceans. Traces of uranium are even found in food and human tissue. However, concentrated uranium ores are found in just a few places, usually in hard rock or sandstone. Uranium deposits are found all over the world. The largest deposits of uranium are found in Australia, Kazakhstan and Canada. High-grade deposits are only found in Canada. It is also found in ocean water.

Iron ore can be found all over the world, in the form of rocks and other minerals. To be economically viable for mining, iron ore must contain at least 20% iron. Magnetite ore has the highest proportion of iron, at 65%. Haematite ore also has a high content of iron at 60%. All iron ore contains ferric oxide and it is from this that iron is extracted. Approximately two billion tonnes of iron ore are mined each year.

Zircon is the oldest known mineral, at over 4 billion years, but the youngest is impossible to say. Minerals are forming all over the Earth at this very moment. You could perhaps safely say that the youngest will be found in the rock of the the latest volcanic eruption.

Sandstone, as its name implies, is composed of many small grains of sand loosely held together. You may be able to rub some off with your hand. The grains will be small and there will be spaces between the grains. Granite on the other hand is formed from the melt underground, and has crystallized there. The crystals will be larger - up to cm size - and firmly bound. [Except if the granite is badly weathered.]

Nuggets found in placer deposits, like Gold.

Gemstones often symbolize important events such as engagements or marriage. Some people also believe they have healing powers or influence over the mood of any location.

Deep blue hope diamond necklace is the most expensive but cursed. Legend has it that anyone who buys the 45.52 carat diamond will have really bad luck such as deaths of loved ones and so on.

The Hope diamond was mined in Kollur in present day Indian state of Karnataka from where it reached the USA after several European royal owners.

However the costliest jewelry around could be the diamond studded crown worn by the Thirupathi Venkateshwara in Andhra Pradesh in India.

Pyrite can be identified as a bright-yellow mineral, with a bright-metallic luster. Pyrite can be used to spark a fire if struck against metal or another hard material. Pyrite was used as a spark-producing material in flintlock firearms.

Panning and cardling were the most popular- as they were inexpensive and not hard to do and in dryer areas people would use the method of dry blowing (panning minus the water) but the big companies would use stamper batteries and other big machinery.

Apparently, over 99% of iron ore commercially used is for steel making. Steel is used in construction (housing/housing appliances), aircrafts, automobiles and containers (steel cans).

When dragged across a streak plate, gold will leave a yellow streak, pyrite will leave a greenish-black streak. It is one way of differentiating gold from pyrite.

Pink Marble is called Tennessee Marble and is a highly pure crystalline limestone. It is pink to cedar-red in color.

the color of crushed pyrite is a greenish brown. Compared to gold which is gold.
