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.

1. 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.
2. 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.

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.

Galena (lead sulfide- PbS) is identified by its metallic luster, light to dark gray color, and high average density of 7.4.

This struggle is known as competition. Organisms must compete with one another for resources such as food, water, and energy when these resources are limited. The competition can be intense and can drive organisms to develop adaptations and strategies to outcompete others for survival.

Granite forms deep underground through the cooling and solidification of molten rock, known as magma. Over time, granite can be uplifted to the surface through tectonic forces, where it is exposed to weathering and erosion. The eroded granite can then be transported and deposited as sediment, eventually becoming buried and undergoing the process of lithification to form new rock, completing the cycle.

Good question! I've done much research on this for my Physical Science class. But the most information I've found and that I can give you is that iron is the predominant metal/element of Earth's core. Iron (and Nickel) mainly take over the Earth's inner and outer cores. But most of the research I have done tells me the Earth is made of 5% iron.

You're Welcome :D

Quartz is a mineral consisting of silicon dioxide (SiO2) and is not classified as a rock on its own. It is one of the most abundant minerals in the Earth's crust and can be found in various types of rocks, including granite, sandstone, and quartzite.

Iron ore is found in various regions around the world, including Australia, Brazil, China, India, and Russia. These countries have significant reserves and production of iron ore due to the presence of large deposits and efficient mining operations.

A clast is a fragment of rock or mineral that is produced by the weathering and erosion of larger rocks. Clasts can vary in size, shape, and composition depending on the parent material from which they originated. They are commonly found in sedimentary rocks.

Quartz and feldspar are the most likely pair of minerals found in felsic rock. Felsic rocks are rich in silica, which forms minerals like quartz, and feldspar is another common mineral found in these rocks.

Gold is a precious metal with a distinct yellow color and is very malleable and ductile. Pyrite, also known as "fool's gold," is a brassy yellow mineral with a metallic luster and a different chemical composition from gold. Mica is a silicate mineral that forms in thin, sheet-like layers and is commonly shiny and flaky in appearance, with no metallic properties like gold and pyrite.

Pumice has a hardness of about 6 on the Mohs scale of mineral hardness.

Oil is extracted from the ground by drilling down hundreds of feet into the earth. Once a discovery is located, a pipe is inserted through which the oil ascends to ground level and is captured into containment areas

Around 1.2 trillion barrels of oil have been pumped from the earth since the beginning of the oil industry in the mid-19th century. It is estimated that we have consumed approximately two-thirds of the world's total oil reserves.

A rock with more silica is likely to be lighter in color, such as light gray or white, due to the presence of minerals like quartz. In contrast, a rock with less silica tends to be darker, as it is typically composed of minerals like mafic minerals (e.g., biotite, amphibole) that give it a darker hue.

Minerals can have various shapes depending on their crystal structure. Common mineral shapes include cubic, hexagonal, prismatic, and rhombic forms. These shapes are determined by the internal arrangement of atoms within the mineral.

Slate is a type of metamorphic rock that does not have the ability to change or adapt to weather conditions. It is a durable material often used in roofing or as a writing surface due to its resistance to weathering.

Some advantages of mining include job creation, economic development in local communities, and access to valuable natural resources that are essential for various industries. Mining can also contribute to infrastructure development and technological advancements.

The specific gravity of iron ore typically ranges from 4.5 to 5.3, depending on the specific type of iron ore. It is a measure of how dense the ore is compared to water, with higher values indicating greater density. This property is important in the processing and transportation of iron ore.
