Mining

lower risks for the miners and lower cost for extracting the ore

In 1996 most iron ore mine workers were union members of the United Steelworkers of America.

No, the mantle is composed primarily of solid silicate minerals rich in magnesium and iron, with smaller amounts of other elements like aluminum, calcium, and sodium. The metallic component is mainly found in the Earth's core, while the mantle is predominantly rocky in composition.

Copper can be found to contain more valuable metal within it, thus making it a bit more valuable.

Industrial technology brought a paradigm shift on the mining in Nevada. It increased the amount of gold produced since gold was first discovered in 1859, attracting more prospectus and money to the state.

Sandstone is used for paving slabs because it is cheap and easy to replace. It is also very popular because it is really easy to cut

Pyrite is weathered by both exposure to sunlight and to rain or temperature variations. The mineral is relatively easily weathered.

Mining is work to remove material to recover a mineral or substance. It's the large-scale blasting, digging, loading, transporting and processing of earth, rock or other material. Searching or prospecting seeks only to locate, map and assess the distribution and concentration of a mineral or substance to gauge the cost-effectiveness of actually engaging in mining.

Bronze is an alloy of (usually) copper and tin. We mine the metal ores separately and then combine them to make bronze.

The four major countries that hematite can be found are Italy, Brazil, England and Australia. In the United States, Michigan and Minnesota are the two major states that hematite is located. Other states include New York, Wyoming, Alabama, Pennsylvania, Colorado, New Jersey and Missouri.

Scientists have this theory on how the moon was formed:

They believe that when the Earth was still a bubbly hot lava thing, something the size of Mars struck Earth, and bits and specks of particles flew everywhere. Gravity pulls it together, and it makes the Moon. Scientists think of this as the best logical theory as to how the Moon was formed, and that the Earth could be just a bit older than the Moon.

500 trillion tons.

One is able to observe the grains in granular pyrite but unable to observe any grains even under hand lens for massive pyrite due to fine grains.

As much as the sellers could charge. Not only mining supplies, but ALL supplies used by the miners. A shovel or pick might sell for $100 (normal price at that time might have been $1.00) and eggs sold for $1.00 each (instead of 12 for a nickel).

Some made money mining gold- some made money selling shovels.

it is extracted from electrolysis of potash.

The lure of quick wealth

Concord, North Carolina, was the site of the Reed Farm in Cabarrus County. Farmer John Reed (aka Johannes Reith, 1752-1845) operated a gold mining operation after his son found a large chunk of gold ore in 1799.

Titanium ores (rutile or ilmenite) are mined in Australia, New Zealand, USA, Canada, Ukraine, Mozambique, China, India, Norway, South Africa, etc.

In the United States, significant copper mining began in 1845, when the Pittsburgh and Boston Company started a mine in Michigan's Upper Peninsula.

Mining and farming in the Western Cordillera occur due to the region's rich mineral deposits and fertile soils. The mountains contain valuable resources such as gold, copper, and silver, attracting mining activities. The valleys and plateaus offer suitable conditions for agriculture, allowing crops such as fruits, vegetables, and grains to be grown.

They sold supplies that were needed by the miners. Supplies like food, shelter, buckets, and other mning tools

Nano steel is an Advanced High Strength Steel, with strength levels > 900 mPa with good ductility. The source of strength is grain size on the order of 1000 times finer (nano meter size) than conventional steel.
