Mining

The value of chert can vary depending on the quality, size, and location of the material. In general, chert is not a highly valuable material compared to other gemstones or minerals. It is often more prized for its use in tools and weapons by ancient civilizations rather than for its monetary value.

Limestone may be mined in a surface quarry, typically by drilling, blasting, and crushing the shot rock. In some areas, limestone mines are underground. In Florida, some limestone mines are under water- the rock is drilled, shot, and mucked while under water. Limestone may be crushed to aggregate sizes, or finely crushed to a powder state for agricultural limestone, or used a "mine safety dust" to control methane and dust in coal mines. Powdered limestone (calcium carbonate) may be roasted and hydrated to form quicklime (Calcium oxide or calcium hydroxide)

True. Copper can be obtained from its ores by smelting, a process that involves heating the ore in a furnace to extract the metal.

"No, gold, silver, and platinum are some of the metals which are not ores".

Yes, these metals do occur as nuggets of native element, and are dredged, or panned from stream, and river sediments, but there are many sulfides, and oxides of these, and other metals as well.

These oxides, and sulfides are the Ore Minerals sought after by prospectors, and mined from in sittu Hard Rock Deposits.

1. Metallic minerals have a high luster and shine due to their reflective properties.
2. They often conduct electricity and heat well due to the presence of free electrons in their structure.

Yes, glass is primarily made from silica, which is a mineral. However, the manufacturing process of glass typically involves adding other materials like soda ash and limestone to improve its properties, which may also contain trace minerals.

Plastic is not mined like natural resources such as metals or minerals. Instead, plastic is typically produced from petroleum-based chemicals through a refining process. These chemicals are then molded into various plastic products through manufacturing processes.

I believe you are referring to strip mining. In parts of Kentucky, Ohio, Pennsylvania, Tennessee, Virginia and West Virginia, entire mountaintops have been shorn off in order to easily get to the coal lying beneath them. A drive up I-75 from Knoxville, TN to Lexington, KY reveals many such examples of strip mining wherein the hills and mountains once had rounded tops, but are now flat on top.

The mineral olivine is (Fe, Mg)2SiO4, or ferromagnesian silicate.

Mica is both mined and extracted. It is typically mined from underground deposits using techniques such as open-pit mining and underground mining. Once the mica-bearing rock is extracted, the mica is then separated from the ore through a series of processing steps.

The depth of the mine can be calculated using the formula: distance = 1/2 * acceleration due to gravity * time squared. Given the time is 6 seconds and the acceleration due to gravity is about 9.8 m/s^2, the depth of the mine would be approximately 176.4 meters.

Without minerals, many essential functions in both living organisms and ecosystems would be impaired. Minerals are necessary for the growth of plants and animals, as well as for maintaining proper bodily functions in humans. Without minerals, soil quality would deteriorate, disrupting the food chain and ecosystem balance. Additionally, industries that rely on minerals for manufacturing products would be severely impacted.

Sodium cyanide is commonly used in gold mining to extract gold from ore. It forms a stable complex with gold ions, allowing for efficient extraction of the precious metal. However, it is a highly toxic substance and requires stringent safety measures to prevent environmental contamination and human exposure.

1. Copper ore is mined and crushed.

2. It must be processed to remove the useful mineral or element.

3. Smelting is the process used to obtain copper. In the smelting the ore is melted and material are removed. After smelting, the copper is refined ,or purified.

4. Then it is made into many types of products used in homes, businesses, and industry.

The smelting of iron equation is typically represented as:

Fe2O3 + 3CO -> 2Fe + 3CO2

This equation represents the reduction of iron ore (Fe2O3) using carbon monoxide (CO) to produce iron (Fe) and carbon dioxide (CO2) as byproduct.

It is processed to separate it from any impurities, cast into ingots then sold as raw material for further processing into the materials for a wide range of applications: bullion, jewellery, electronics components, medical equipment and so on.

Rocks and minerals are made up of various types of atoms such as silicon, oxygen, aluminum, iron, calcium, and others. These atoms are naturally occurring elements that form different combinations and structures to create the wide variety of minerals found in nature.

Mica is commonly found in thin, transparent sheets that can easily be split into layers. It is known for its unique physical properties, such as flexibility, heat resistance, transparency, and electrical insulation. Mica is often used in electrical components, cosmetics, and as a pigment in paints and ceramics.

Nickel is mined in various countries around the world, with major producers including Indonesia, Russia, Canada, and Australia. These countries have significant nickel deposits and mining operations that contribute to global nickel production.

Life was rough in mining towns. Few women or families came with the miners. The women that did end up in the gold towns generally were prostitues or did miners laundry. There is a reason why the gold rush towns had names like Hangtown.

It's real name is Tiger Eye, but according to mindat.org it is a combination of chalcedony, a variety of quartz, and riebeckite, an amphibole mineral.

No, this statement is not accurate. Ores containing methane, such as coal beds, are considered to be non-renewable resources because they are finite and take millions of years to form. Methane itself is a natural gas that can be considered a non-renewable resource as well.

The environment is defined as the surroundings of man and other living things. It comprises of four major components namely: Hydrosphere (Water bodies), Atmosphere (air), Lithosphere (earth's crust) and Biosphere (living things).

Hydrothermal processes are responsible for creating ore bodies at divergent plate boundaries. When water interacts with hot rocks, it dissolves minerals and can concentrate them in fractures and openings, forming valuable ore deposits. This process occurs in hydrothermal vents along mid-ocean ridges where new oceanic crust is forming.
