Mining

overburden

A metamorphic rock.

Zinc is associated with copper and lead in sulfide minerals.

It is the same way as mining other ores as well as coal. The only difference (for all different ores you want to mine) is the rock you mine from. Make sure it has gold colour.

All substances are MADE FROM elements but they are not elements. For example CH4 is made of one carbon atom and four Hydrogen atoms. Carbon and Hydrogen are pure elements but CH4 is not an element.

Renewable refers to things like wind or sunshine, which keep on coming even if we use them to produce energy. Other things are classed as renewable if we can grow them as fast as we use them. Like vegetables. Other things get used up and don't renew, like rain-forests and minerals.

So bronze is non-renewable. It's an alloy of copper and tin, usually. When we use it all up, there's none left. All we can do is recycle it.

Common iron ores include

Iron Oxides:

Magnetite (Fe3O4)

Hematite (Fe2O3)

Other iron ores include

Geothite FeO(OH)

Limonite (FeO(OH).n(H2O)))

Siderite FeCO3

Gold mining is controlled by the government because there is a lot of money at stake.

The Sierra Nevada Mountains.

a rock with a layer of oil on it.

As of 2009 there were no active diamond mines in Saskatchewan, but the area around Fort a La Corne is being actively explored and contains large amounts of kimberlite, which is being tested for profitability. Time will tell whether there are enough diamonds to justify a mine, which could cost $2 billion to get into production.

Well, one answer is saloons- to remove the gold from the miners! However, once the easy placer gold was mined from the streams, mining companies that sought to mine the rock that the placer gold came from moved in, and began mining gold ore that required processing to extract the gold.

Longwall and shortwall mines use huge machines with cutting heads. The heads are pulled back and forth across a block of coal up to about 150 feet long in shortwall mining, though much longer in longwall.

Per unit, a bit more than other minerals. But mining runite is extremely slow, so if it is experience you want, better get iron.

We see the application of the term mine (as in land mine) to a high explosive weapon that can be set on or beneath the ground, and which is triggered by someone stepping on it or a vehicle rolling over it.

The same name applies to a similar nautical weapon that floats at or just below the surface and is detonated when hit by (or sometimes by the proximity of) a ship.

They worked in coal mines and some children didn't servive in the mines because of all the fumes.

"African" is not a language. Africa is a continent that contains 54 countries and more than 2100 completely different languages. Some estimates place the number of languages at around 3000.

If you have any quesitons about African languages, you will have to specify the language.

The most prominent languages spoken in Africa are:

Afrikaans

Amharic

Arabic

English

French

Fula

Hausa

Igbo

Oroma

Somali

Swahili

Yoruba

Zulu

They were unruly mud holes with crude men looking for gold. No services, no schools, no churches, no government. They had tents, bars, and "ladies of the night", a few stores sold food, shovels, gold pans, and clothing. They were no place for a family.

Between 1812 and 1860, the growth of cotton and iron industries meant that coal was at a higher demand. New technology was introduced to try to make coal production quicker and more efficient. Cage elevators were introduced to raise coal and miners from the pits, rails and carts were used to transport coal, instead of 'Putters', some mechanical machinery was introduced to cut coal, instead of the 'Hewers' doing it by hand. The invention of the davy safety lamp meant that miners could go deeper into mines, but it also lead to many injuries.

You just smelt out the iron and collect both the iron and sulfur remaining, or by weathering the pyrite you can rust away the iron and use water to collect the sulfur as sulfuric acid.
