What are 5 minerals mined in the US?
There are many minerals mined in the United States. Here are five: *Coal *Gold *Magnesium *Gypsum *Copper These are only five of the many.
What is the best reservoir rock?
Porous sandstone is a good reservoir rock for its porosity enables it to store the fluid (oil?) and also to allow easy release.
Compare with oil shale, where the rock is very fine grained and will not release the fluid easily.
Both would ideally be capped with an impermeable cap rock to constrain the oil.
How does uranium mining give off carbon emissions?
Uranium mining involves machinery and transportation that run on fossil fuels, emitting carbon dioxide during operations. Additionally, the processing of uranium ore into fuel for nuclear reactors also requires significant energy, contributing to carbon emissions from the electricity generation process.
What is 1 way that mining for mineral resources damages the land?
Mining for mineral resources damages the land by causing deforestation and habitat destruction. The excavation process can lead to soil erosion, contamination of water sources, and disruption of ecosystems, impacting wildlife and plant species.
Where is the largest granite quarry in the world?
The Rock of Ages quarry is in Barre, Vermont. This is the largest granite quarry in the world, covering 24 acres and nearly 300 feet in depth.
What is the largest copper mine in the world?
The Escondida copper mine in the Atacama Desert in Chile is the Worlds largest copper mine.
What are the effects of bauxite mining?
It pollutes the environment and destroys animal's habitats.
The first effect is that of the extraction of the minerals from the ground.
These should also include the resources necessary to do this - the fuels, metals, and so on.
Transport of the bauxite to the refining site is the next contributor, with similar side effects to the extraction phase.
The refining of the bauxite into aluminum is very energy intensive, and considering this phase, one should consider the alternate uses to which this energy could have been put.
Bauxite is refined by an electrolysis process, and consumes silica and carbon as part of that process, but also emits fluorine into the atmosphere. Which is not a nice chemical.
What are some common uses for rhenium?
Rhenium is commonly used in high-temperature superalloys for aerospace applications, as a catalyst in the production of gasoline, and in the manufacturing of electrical contacts and filaments due to its high melting point and resistance to corrosion.
Gold is typically harvested through mining, where gold ore is extracted from the earth using various techniques such as open-pit mining or underground mining. Once the ore is extracted, it is processed to separate the gold from other minerals, usually through a combination of crushing, grinding, and chemical processes. Finally, the extracted gold is refined into pure gold bars or other forms for commercial use.
Why do people set land mines in the ground?
People set land mines in the ground as a form of warfare to restrict enemy movement, protect valuable resources, or defend borders. Land mines are designed to explode when activated by pressure or proximity, causing injury or death to those nearby.
Is limestone mined in a open-pit mine?
Yes, limestone is often mined in open-pit mines where the rock is quarried by blasting and then loaded onto haul trucks for transport. This method is commonly used due to the shallow nature of limestone deposits and the relatively low cost of extraction compared to underground mining.
How can silver mining have a negative impact on the environment?
I am not a 100 percent sure i am right but here i go...
Silver is a negative impact on the environment because it has to shipped to different country through oceans on boats which produce oil into the water.
BTW i am just guessing
Where in the us are talc mines generally located?
Talc mines in the US are generally located in states like Montana, Vermont, Texas, and California. Montana, specifically, is known for having large talc reserves and being a major producer of talc in the country.
What are the 3 main parts of the Earth?
The three main parts of the Earth are the crust (outer layer), mantle (middle layer), and core (innermost part). The crust is the thinnest layer and where we find land and oceans, the mantle is made up of solid rock that flows slowly over time, and the core is composed of a mostly iron-nickel alloy.
Why can you use phytomining when it would be too expensive to extract metals in other ways?
I had this question set too. I wasn't sure but I think it's because it is a natural way of extracting metals because the plants naturally absorb the chemicals from the ground. Also because the technology used to create the metals are simple to use.
How much copper is left in the world?
It is estimated that there are about 5.6 trillion pounds of known copper reserves left in the world. However, the total amount of copper resources, which includes undiscovered deposits and unconventional sources, is much higher. The exact amount of copper left in the world will depend on future discoveries and advancements in mining technology.

Why do we quarry?
For thousands of years man has used stone for building, whether it was for monuments, religious buildings or houses. Early on, when Britain was only sparsely populated, man's use of stone and his primitive quarrying would have had little lasting impact on the environment. Gradually, as time went on, more stone was used in building. It was a good material with which to build castles, walls, churches and important buildings since it was strong and weather resistant. As the demand for stone grew, so did the demand for quarrying.
During the Industrial Revolution demand soared. The Victorians used stone for all their major buildings and with better transport and new technology they were able to meet these increasing demands, probably with little thought as to their impact on the environment.
What do we quarry?
Today the demand for carefully worked stone for building has been reduced by the fact that we have so many new, easier to use and cheaper building materials but this does not necessarily mean that there is less quarrying. Although stone blocks are not used so much for building as they used to be, we still use stone in a different form for building and construction work today.
There is now a great demand for stone - especially limestone - in the form of 'crushed rock' and it is also an essential constituent in other building and construction materials.
Creating one kilometre of road 10 metres wide could use well over 500 lorry loads of crushed stone.
Because the stone used for this sort of construction work does not have to be extracted in a high quality block form, the techniques for quarrying have changed. Now, those that quarry can be less selective. Consequently one of the best methods of quick quarrying is the use of explosives which means that great chunks of hillsides may be blown up and transported away in a relatively short time.
Sand and gravel are used along with stone in construction work. Consequently millions of tonnes are being removed from sand and gravel deposits both on land - usually close to the urban areas where they are needed - and also from the sea bed.
What are the Advantages of rock salt mining over solution mining?
Rock salt mining has lower operating costs as it requires less energy and equipment compared to solution mining. It also has fewer environmental impacts since there is no need for large volumes of water to dissolve the salt deposits. Additionally, rock salt mining is typically more straightforward in terms of extraction and processing compared to solution mining.
Bio-prospecting can be best understood by splitting them into two parts:-
Bio- any biological material (floral or faunal parts)
Prospect- it's prudential use
therefore, bio-prospecting means exploration and buying of biological materials for studying and then to finally change them into products of commercial interest
Biotite is mined in North W.A
dnt noe if its rightt, cuz im only 11! IM DOING MY HOMEWORK IT SAYS ITS MINED IN NORTH WA BUT I DUNNO IF IT IS BIOTITE! ....anyway... tell mee wat ya think :)
Galena has a hardness of 2.5 on the Mohs scale. It has a specific gravity of about 7.4. to 7.6. Galena is main mineral in which lead is found.
Azurite is typically mined through traditional mining methods such as open-pit mining or underground mining. Miners locate azurite deposits, extract the ore using equipment like drills and explosives, then transport it to a processing facility for extraction of the azurite mineral. Environmental and safety regulations are typically followed during the mining process.
- Reclamation requirements: Mining operations are often required to restore the land to its original state post-mining, including backfilling open pits and re-vegetating the area to reduce erosion and restore wildlife habitats.
- Water management controls: Mining operations must implement measures to prevent contaminated water from entering nearby water bodies by treating it on-site or using sediment and erosion controls to minimize the impact on water quality.
How is ore extracted from the ground?
The general term we apply to ore extraction from the earth is mining, and mining technology or mining engineering are the disciplines under which mining is practiced. Need a link? You'll find one below to the Wikipedia post on mining. If your question is applied to the mechanics of mining, we have to locate and map deposits of mineral ores. Then sample and test them for concentration ("richness"). Then either dig a shaft or start removal of overburden to form a pit. We can drill to set charges, blast, and then send in men and equipment to remove the material and get it out to a place from which it can be routed to processing, either on site or at a remote location.
What is the density of galena?
Galena (lead sulfide- PbS) is identified by its metallic luster, light to dark gray color, and high average density of 7.4.
