Mining

Open pit mining has been done since prehistoric times. At first, a quarry was probably opened to recover stone used in building. In this light, no one person or group can claim the introduction or "invention" of open pit mining. Certainly the scale on which we conduct open pit mining today doesn't begin to compare with these ancient methods. But the simple idea of opening a hole in the ground to recover useful material has been brought forward and continues.Daniel Jackling first introduced open-pit mining

No, gold does not reform once it has been mined out of the ground. Once gold has been extracted from the earth, it retains its physical and chemical properties. It can be melted, reshaped, and reused, but it does not regenerate or reform on its own.

Open pit mining is a widely used mining technique developed centuries ago, and it is difficult to credit a specific individual with its invention. However, open pit mining has been practiced throughout history in various forms, with the ancient Romans known to have used similar methods for extracting minerals. The technique has evolved and is now a prevalent method in modern mining operations.

The deepest gold mine in Africa is the Mponeng mine, located in South Africa. It reaches a depth of around 4 kilometers (2.5 miles) below the surface. The mine is operated by AngloGold Ashanti and has been in production since 1986.

it costs way to much to mine and to much energy

yes

they can be used for jewelry and even lotion!

There is no Latin word for manufacturing, but there is a French word for manufacturing and it is fabrication.

In the US, at least 18.

No, you really don't want to live near a gold mine if you can help it. People report that their quality of life is greatly diminished. You would be dealing with noise, dust (containing possibly dangerous particles), and vibrations, among other problems.

Mining Engineers earn $180,000-$200,000 per month.

In Northern Ontario, Canada, the gold mines blast rock into smaller pieces, then use cianide to eat the iron ore and granite, leaving gold. This is melted and formed into "buttons", not bricks. Buttons are about a million $ worth of pure gold.

Hard rock mines, the type always shown in old cowboy movies where there are long passages held up with wooden beams are used in the mining of:

* Minerals such as gold, lead, uranium and silver * Halite (rock salt) * Coal * Opals * Diamonds Open pit mines are used to extract materials like coal and are essentially hust large holes that grow bigger as more material is removed. Open pit mines also describe some types of oil sands operations.

Solution mines use liquid to remove minerals from undergroud strata by pumpimg down a solvent (water) and pumping up asolution of the water and the sesired mineral (salt, sulfur, potash)

DUSTY, Is just one of the aspects of coal mining. Do not forget wet from head to toe, either from the top like falling rain or big pools that must be pumped into sumps. Your cold if you are by the slope or sweating hot if you work along the face or belt line. It is a difficult life and I have seen many get injured, crushed, and disabled for the rest of their future. It is a job and people must have energy. However, If you are young, experience other jobs first. This should be a last option. I am saying it is honorable for American miners, however, it will make you a hardened man or woman. So much, that you may not like yourself in the future for all the aches and pains you live with day after day.

Before mining can begin, the land is cleared. The first issue is deforestation. Deforestation immediately destroys wildlife habitats. As the land is cleared and low bushes and vegetation burned and destroyed, wildlife either moves on or dies

Canaries were once regularly used in coal miningas an early warning system. Toxic gases such as carbon monoxide and methane in the mine would kill the bird.

The biggest danger in retreat coal mining is the miners are removing coal pillars as the miners "retreat". The removal of coal pillars, which support the mine's roof, can cause mine collapse.

No, minerals are not alive. A mineral is a naturally occurring solid. The seven characteristics of life are Sensitivity, Breathing (or respiration), Movement, Growth, Feeding, Excretion, and Reproduction. Nothing of the characteristics are held by a mineral.

Develop wind power to it's maximum potential.

Mining can cause pollution of the ground and water, and imperil the lives of workers unless safety precautions are followed.

Answer:

There are many folk-cures and hear-say remedies for growing plants, many if not most will end in weakening if not killing the plant, the best recourse is to know the plant, know what type of soil it likes, and what kind of nutrients it requires, (well balanced nutrient filled diet) the simple course of action would be: Water, Air, Sunlight [full/partial/defused] and a mild form of fertilizer, keeping in mind not to over water or under water.

SPRITE OBVIOUSLY MAKES A PLANT GROW FASTER

The state of North Carolina leads in the production of tobacco as well as in the manufacture of furniture and textiles. The capital of North Carolina is Raleigh.

California gold miners didn't eat "in the mines" they ate at their camp. Usually it was very simple food since everything was cooked over a campfire. Pancakes were popular, eggs (though they could be expensive in the camps), beans, hardtack, (thick, stone hard crackers) coffee was popular, dried peas, chicken, rabbit, and a steak if they found gold. It was a rough life and often the men were sick, wet, and dirty. Bread was an important staple in any miners diet. It was cheap, and easy to make. Many miners cooked their food, and even baked bread in a "Dutch Oven", a large, cast iron pot with a tight fitting lid. They first made their own yeast by allowing flour and water to ferment in a warm place, this was the "starter" for sour dough bread, biscuits, pancakes and more. When the starter was mature, they would take a scoop out, add flour and make the bread dough. They let it rise in the dutch oven near the fire while they slept. In the morning they would dig a hole next to the fire, put hot coals into it, put the dutch oven in, add more coals, and cover it over with dirt and go off to their mine to work. When they came back to camp at the end of the day, the bread was baked and ready to eat.
