Mining

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.

Plutonium occur in deposits of uranium ores but only in ultratraces. In the nature plutonium appear as a result of spontaneous natural fission of uranium isotopes a process with a very low cross section.

A cut ruby is smooth and very hard, like a diamond. An uncut ruby may be rough and bumpy and still have sediment around it.

One common method to separate components of a mineral mixture in the mining industry is through a process called flotation. This involves adding agents to the mixture that selectively attach to and float one component while leaving the other behind. Another method is using gravity separation, where the different components settle at different rates due to their density differences, allowing for separation.

To mine the iron you need a lot of land. This usually means cutting down trees - deforestation - which is bad for the environment. It destroys habitats and disrupts wildlife, and ruins the natural environment. Also, dust and sound pollution are a problem. Once the iron is mined, transporting it pollutes the air.

If this is for homework, you can copy word for word I don't care :-)

A mineral structural group refers to minerals that have similar crystal structures due to their chemical composition and arrangement of atoms. These groups help classify and categorize minerals based on their internal structure and bonding characteristics. Examples of mineral structural groups include silicates, carbonates, sulfides, and oxides.

Copper is mined through open-pit or underground mining methods. In open-pit mining, large machinery and explosives are used to extract the ore from the earth's surface. In underground mining, tunnels are dug to access the copper ore, which is then extracted using various methods such as blasting or drilling.

A clay catalyst is a type of catalyst that is based on clay minerals. These catalysts are used in various chemical reactions to increase the rate of the reaction and improve selectivity towards desired products. Clay catalysts are known for their stability, reusability, and low cost.

Granite is mined out of the ground in large blocks, usually up to 3metres long by about 1.5 metres square. These individual blocks are cut into multiple'slabs' of the requisite thickness, usually 20mm or 30mm thick, using a huge reciprocating arm attached to a series of blades. It's a bit like a bread slicer, only it takes a bit longer to cut through, usually about a week
