Mining
Mining for coal is something that is widely known, but did you know that diamonds, uranium, copper, and other non-renewable natural resources are also mined? There are two types of mining; surface and subsurface. Questions about the methods and types of mining, what ores are mined, and related questions should be asked in this category.

What is a layer of ore called?
A layer of ore is called a mineral deposit or an ore deposit. It is a concentration of ore minerals within the Earth's crust that can be economically extracted for use in various industries.
How long has whatley quarry been around?
Whatley Quarry has been in operation since the 1930s, with quarrying activities starting in the 1960s. It is one of the largest limestone quarries in the UK and has been supplying construction materials for over 50 years.
Pieces of quartz free on the surface and not in the bed rock, as it has eroded from the a quartz vein and rolled and or washed to its current location.
Iron ore typically feels heavy, dense, and often gritty or coarse due to the presence of mineral particles. It can vary in texture depending on its composition and any impurities present in the ore. Some types of iron ore may also feel slightly magnetic due to their iron content.
What is the history of iron mining?
The mining of iron ore only began after the 1830's. During that time there was a shortage of aluminum and titanium, so various industries began substituting with iron and einsteinium for building material. Since then, iron has continued to be mined, as it has the highest compressive strength of any material known to man, and it is over really cool looking in machinery.
What is the smelting temperature of a gold ore?
The smelting temperature of gold ore typically ranges between 1,600 to 2,000 degrees Fahrenheit (870 to 1,100 degrees Celsius). This high temperature is required to melt and separate the gold from other minerals in the ore during the smelting process.
What are some disadvantages of Uranium mining?
Some disadvantages of uranium mining include environmental damage from pollutant releases, potential health risks to workers and local communities due to radiation exposure, and the risk of nuclear accidents associated with processing and transportation of uranium. Additionally, there are concerns about the long-term storage and disposal of radioactive waste produced from uranium mining.
What is the major difference between mineral characteristics and mineral properties?
Mineral characteristics refer to the physical and chemical features that define a mineral, including its crystal structure, composition, color, and hardness. Mineral properties, on the other hand, are specific attributes used to identify and differentiate minerals, such as luster, streak, cleavage, and specific gravity. Characteristics are intrinsic to the mineral itself, while properties are observable and measurable traits used for identification.
What does coal and iron ore combined make?
Coal and iron ore are often combined to make steel. The coal is used as a source of carbon in the steelmaking process, while the iron ore provides the necessary iron content. The two materials are melted together in a blast furnace to produce molten steel.
Granite counter tops cost 48$-150$ per sq. foot Granite tile cost $4-$20 per sq. foot. The price of granite very's so much that it mostly depends on the type of granite. Example:
Granite tile price's at home depot:
$5.00 sq. foot for black granite
$7.00 sq. foot for Brazilian green granite
$10.99 sq. foot for tan brown granite
and for counter tops, it cost $48.00 sq foot. at the lowest.
Note: prices are of 6/28/10 this is not from home depot. And the price of granite changes from year to year.
Lutetium never is found alone. Instead, it's found in the earth's crust, along with other rare earth metals. Specifically, there's a chance of finding it where the element yttrium occurs. Lutetium is difficult and expensive to isolate and prepare. As an uncommon and costly rare earth metal, its occurrence tends to encourage its mining only in Australia, Brazil, China, India, Sri Lanka, and the United States of America.
Answer by TedlyW
The rare-earth element Lutetium was first discovered as an impurity in samples of ytterbia. Six times as expensive as gold, lutetium is today found in small concentrations within the rare earth phosphate mineral monazite. Monazite has been found in many places, even in North Carolina in the U.S. But commercially viable deposits today are worked only in Brazil and southern India. Large monazite sand deposits tend to have come from the erosion of large masses of certain granites and gneiss.
"No conclusive" means that there is not enough evidence, information, or proof to confirm a definitive conclusion or decision. It indicates uncertainty or lack of finality in a particular situation or outcome.
Does Platinum occur with Gold ore?
Yes, platinum can occur with gold ore in some deposits. These are known as platinum-rich gold deposits and typically contain both gold and platinum group elements. These deposits are rarer than typical gold deposits.
How do you extract gold from copper ore?
Gold can be extracted from copper ore through a process called cyanidation, where a cyanide solution is used to dissolve the gold from the ore. The resulting solution is then processed to recover the gold through a series of chemical and physical processes.
Minnesota led the world in the mining of what element?
Minnesota led the world in the mining of iron ore.
What is the name of the main ore of silver?
Argentite, or silver glance, is the most important and common of silver minerals.
Pyrite is sometimes called fool's gold because of its metallic luster and pale brass-yellow hue, which can resemble real gold to the untrained eye. However, pyrite is a different mineral with a lower value and hardness compared to gold.
How and where is uranium obtained?
See the link below for uranium mines; the preparation of pure uranium metal (or other compounds) from ores is a long and expensive work.
Chemical engineering processes and other processes are of course involved: radiometric sorting, grinding, dissolving, filtration, separation with ion exchangers, separation by solvent extraction, precipitation, calcination, etc.
What is the formula for Biotite Mica?
Mica's chemical formual is:
Si0 2 05 and oH
2 sillicon
5 Oxygen
oH hydrated
Are there any quarries in Pennsylvania?
Yes, Pennsylvania has several active quarries that mine for materials like limestone, sandstone, and granite. These quarries supply materials for construction projects, road building, and landscaping throughout the state and region.
How can you get iron out of rock?
Iron is extracted from iron ore simply by heating the ore, a process known as smelting.
This depends on the rock.
If the rock contain IronOxide (of which many do), then heat alone is not enough.
When adding heat to Iron Oxide, you get melted Iron Oxide, of which is of hardly any use to anybody as such.
The trick is affinity of materials.
Oxygen has got a high affinity for Iron but an even greater love for Carbon.
This is why one (Espechally in olden days) uses loads of charcoal when melting the rock containing IronOxide.. The material melts. The oxygen breaks up its relationship with Iron and falls in love with the carbon instead.
This leave the Iron alone, it melts and forms at the bottom.
One can also use electricity in order to force affinity to where there normally is none.
If rocks have got Iron bound other ways, electricity can be used, but always together with high heat.
I suppose one could "burn" the rocks (Not that they burn, but they heat up) so that the Iron inside reacts with Oxygen forming IronOxide. Then use that product together with charcoal separating and leaving the pure Iron.
It takes a lot of energy to produce Iron.
+++
Yes, charcoal was used in the early days as fuel and reagent but this was replaced by coke (coal burnt in low-oxygen conditions to drive off its volatile and gaseous compounds). Coke has a far higher calorific value than charcoal, so is far more efficient as a fuel, and the effiency of the Blast Furnaces in which the process takes place is raised still further by using the very hot exhaust gases to heat the incoming air.
The last paragraph does not make sense. The "rocks" are Iron Ore, which is Iron Oxide, so the reaction can only be one that separates the iron from the oxygen.
No, metal ores are naturally occurring minerals that contain metal elements in their chemical composition. They are formed through geological processes such as volcanic activity, sedimentation, and metasomatism over millions of years.
What are the mineral resources in Iceland?
Iceland's mineral resources include geothermal energy, silica, and diatomite. Additionally, the country has deposits of zeolite, sulfur, and gypsum. However, Iceland does not have significant deposits of traditional metals like iron, copper, or gold.
Pyrolusite is a manganese oxide mineral, that has yet to cause any fatalities. It could kill you if you grind it very fine and inhale it, or eat enough of it, or drop a block of it on your head, but other than that it's not much of a hazard to anybody.
