Mining

Nickel can be mined in various countries around the world, with major producers including Indonesia, the Philippines, Russia, Canada, and Australia. These countries have significant nickel reserves and play a key role in global nickel production.

No, your pencil-lead is made out of graphite and pencils are cheap.. so.. mining graphite would be..... cheap! == Expensive is a relative term. If you consider the expenditure of large sums of money to purchase excavating equipment, offices, large trucks, processing equipment, insurance, labor, payroll taxes, accounting, compliance with government safety and environmental regulations, and so on......it doesn't sound cheap anymore.

Yes, minerals are composed of atoms. They are naturally occurring inorganic substances with a specific chemical composition and a crystalline structure formed by the arrangement of atoms.

Aluminum is found in the crust of the Earth. It makes up the third most abundant element in the Earth's crust, following oxygen and silicon, and followed by iron. It makes up roughly 8% of the Earth's crust, so this element is not very rare.

Aluminum is a cheap metal. It is useable for everyday things like aluminum foil and soda cans.

The most economical ore for processing is bauxite -- hydrated aluminum oxide, often with hydrated iron(III) oxide as an impurity. Bauxite is found in many places around the world, but mostly in tropical countries.

Australia is the world's largest producer of aluminum/alumina, with a major resource at Weipa (Gulf of Carpentaria), and Indonesia, China, and Brazil following. Guinea and Vietnam probably have larger reserves.

Petroleum is not a mineral because it is an organic substance derived from the remains of ancient plants and animals, while minerals are inorganic compounds with a crystalline structure formed in nature. Petroleum is a complex mixture of hydrocarbons, whereas minerals are naturally occurring solid substances with a specific chemical composition.

The mining industry finds paleontology useful because studying fossils can help identify potential mineral deposits. Fossils can indicate the presence of certain minerals or the geological conditions that may harbor valuable resources. This information can aid in making informed decisions about where to explore and extract minerals.

Iron can be found naturally in the Earth's crust, primarily in the form of various iron ores such as hematite, magnetite, and siderite. It is commonly extracted through mining operations in locations with abundant iron deposits. Additionally, small amounts of iron can also be found in various minerals and rocks.

The lithosphere is the rigid outer layer of Earth consisting of the crust and uppermost part of the mantle. It is composed of solid rock materials, such as granite (continental crust) and basalt (oceanic crust), which vary in thickness and composition depending on location. The lithosphere also includes tectonic plates that float on the semi-fluid asthenosphere beneath.

Since water has a specific gravity of 1, the mineral with a specific gravity of 5.5 is 5.5 times denser than water. This means that there is 5.5 times more matter in 1 cm cubed of the mineral compared to water.

Large crystal formation in mineral specimens typically occurs when the mineral is allowed to grow slowly under ideal conditions, such as low temperature, high pressure, and limited space for crystal growth. These conditions promote the orderly arrangement of atoms within the mineral structure, leading to the development of large crystals. Factors like the presence of impurities, the mineral's chemical composition, and the length of time the mineral has had to grow can also influence crystal size.

The Amazon rainforest in Brazil and other tropical rainforests are known to produce a significant amount of oxygen. Additionally, countries with large areas of forested land, such as Russia, Canada, and the United States, also contribute significantly to oxygen production. Ultimately, the total amount of oxygen production is a result of global forest cover and plant life.

Calcite is non-silicate, containing no silicon elements.

Dynamite was used in mining to break up rocks, ore, and other materials. It was typically placed in drilled holes and then detonated to create explosions that would fragment the material for easier extraction. Dynamite revolutionized the mining industry by allowing for more efficient and controlled excavation processes.

The ore of mica is called "muscovite." It is a type of mica mineral that is commonly found in metamorphic and igneous rocks. Muscovite is known for its pearlescent luster and excellent cleavage properties.

Gold is typically extracted from gold ore using a combination of chemical processes. The most common method involves cyanidation, where cyanide solution is used to dissolve the gold from the ore. The dissolved gold is then extracted from the solution through adsorption onto activated carbon, followed by refining to obtain pure gold.

China comprises for 90% of Antimony production, followed by South Africa, Russia and Bolivia

Small crystals are called microcrystals. These tiny structures are often too small to be seen or examined without the aid of a microscope.

Silica is seen commonly in nature as sandstone, silica sand or quartzite. It is one of the most abundant oxide materials in the earth's crust. There are three crystalline forms of silica: quartz, tridymite, and cristobalite.

The compass rose has appeared on charts and maps since the 1300's, the term comes from the figure's compass points that represent the petals of a rose. It was first used to indicate the direction of the wind and was known as a 'wind rose'. The 32 points on the compass came from the direction of the winds.

Mineral oil is absolutley insoluble in water. The old saying that oil and water do not mix definitely rings true for this oil. You can, if you need to, go through and intermediary such as IPA (isopropyl alcohol) and then to water. I do this all the time in the lab. Paul

It is definitely a form of the mineral quartz, maybe jasper or carnelian.

The sea smashed into the Headland (when there was one) which then created a archway. The archway then fell into the sea, the stack nearby is a bit off the old headland that has shown as the water level has fallen.Then it built up by quarul.
