Mining

India is the top producer of mica in the world, accounting for a significant portion of global mica production. The majority of mica in India is extracted through illegal and unregulated mining practices, leading to concerns about child labor and environmental damage.

Ferromagnesian silicates are those minerals containing ions of iron (iron=ferro) and/or magnesium in their structure. Because of there iron content, ferromagnesian silicates are dark in color and have a greater specific gravity, between 3.2 and 3.6, than nonferromagnesian silicates. The most common dark silicate minerals are olivine, the pyroxenes, the amphibloes, drk mica (biotite), and garnet.

Yes, iron ore is considered a finite resource because it is a natural mineral that exists in limited quantities in the Earth's crust. Extraction of iron ore can lead to depletion of reserves over time if not managed sustainably.

Advantages of underground mining include fewer environmental impacts, such as reduced greenhouse gas emissions and land disturbance, compared to surface mining. It can also have less impact on local communities and reduce the risk of accidents from vehicles or equipment traveling on the surface. Additionally, underground mining can access deeper mineral deposits that may not be feasible for surface mining.

Forms of subsurface mining include drift mining, slope mining, shaft mining, and room and pillar mining. These methods involve accessing minerals or resources beneath the Earth's surface through tunnels, shafts, or other underground workings.

No, not in the current sense of the word.

However, because diamonds are formed deep within the earth's mantel, new diamonds are probably being formed now. And it will take millions of years for those stones to be completely formed and erupt to the earth's surface where they can be discovered.

Vein mining is a mining technique where a player systematically mines all blocks of a particular type (such as ores) within a vein or deposit without leaving any behind. It involves clearing out the entire vein of ore rather than just mining specific blocks, resulting in more efficient resource gathering.

There are hundreds of uranium mines worldwide, with major producers located in countries like Kazakhstan, Canada, Australia, and Namibia. The exact number of uranium mines fluctuates as new mines are developed and others are closed due to market conditions.

No, Bauxite is not a type of iron ore. it is an ore of aluminum.

One of the largest excavations in the world has been made by opencast mining at the Bingham Canyon copper mine in Utah, USA, measuring 790 m/2,590 ft deep and 3.7 km/2.3 mi across.

Underground mining is a method of extracting minerals or resources from beneath the Earth's surface through shafts, tunnels, and chambers. This method is employed when the mineral deposit is deep or too dangerous to extract through surface mining.

Slope mining is a method of accessing valuable geological material, such as coal. A sloping access shaft travels downwards towards the coal seam. Slope mines differ from shaft and drift mines, which access resources by tunneling straight down or horizontally, respectively.

There are several, the main ones are coal, chalk and stone for building purposes. Many countries have restrictions on open cast mining and there are regulation for repairing the land afterwards.

Geologists are interested in the history of the earth because they want to know how the world became what it is today. Geologists study the history of earth because it's a thing they've grown to like and are in to. History is a major part of earth and the way of life, someone has to know the statsitics.

Health risks of mining bauxite include exposure to dust and chemical fumes, potentially leading to respiratory issues and skin irritation. Environmental risks include habitat destruction, water contamination, and soil erosion. Additionally, mining bauxite can contribute to deforestation and loss of biodiversity.

Shale can be turned into slate through metamorphism, which involves applying heat and pressure to the shale over time. This process causes the minerals in the shale to recrystallize and align, creating the distinct layers, smooth texture, and foliation characteristic of slate.

Gold can be found at varying depths in the Earth's crust, typically ranging from a few meters to a few kilometers deep. Commercially viable gold deposits are usually found at depths of hundreds of meters to a few kilometers below the surface, where geological conditions have concentrated the gold into mineable ore bodies.

Iron ore is commonly transported using trains, trucks, and ships. Trains are often used for long-distance transportation from mining sites to processing plants or ports. Trucks are typically used for shorter distances within mining sites or between processing facilities. Ships are used for bulk transportation of iron ore across large bodies of water to reach international markets.

The difference between surface run-off and subsurface run -off is that surface run-off is that when it is precipitation the water goes on the ground like a river and lake. The water that goes on the top of the ground is going to the oceans. The subsurface run-off is that when it is preciptation the water

Crusher dust is a byproduct of crushing stone or rock. It is used as a compacting material and is often mixed with cement to create a solid surface for pathways, driveways, and other construction projects. It can also be used as a base material for landscaping projects.

The circulatory system is responsible for transporting oxygen, nutrients, hormones, and waste products throughout the body. It consists of the heart, blood vessels, and blood. The system plays a crucial role in maintaining homeostasis and supporting overall bodily functions.

spatial mining is the extraction of knowledge,spatial relationships and intresting measures that are not explicitly stored in spatial database where as temporal mining is the extraction of knowledge about occurence of an event or values whether they follow cylic,random,seasonal variation etc...and other intrestion time related patterns.

Shale turns into slate through a process called "low-grade metamorphism." Under heat and pressure, the clay minerals in shale recrystallize to form very fine-grained mica minerals, giving slate its characteristic layering and foliation. This metamorphic process occurs at temperatures between 200-450°C and pressures of 200-300 megapascals.

Define "recover." If you mean as, say, farmland or for some similar use, one needs to remember that the mineral-rich and fertile layer on which vegetation grows is a thin shell on the earth, mostly created by decomposing matter and similar deposits. Strip mining removes this thin shell to get to the minerals below. Since it's truly difficult to rebuild a suitably fertile topsoil, it's therefore difficult to recover strip-mining activities.

Talc has been used by humans for thousands of years and its discovery dates back to ancient civilizations. It was used by Egyptian and Greek cultures for various purposes including cosmetics, medicines, and sculptures.
