Mining

Other mineral properties such as luster, streak, and specific gravity are less useful for identification because they can vary widely among different minerals and may not be unique to a specific mineral. In contrast, properties like hardness and cleavage are more consistent and can help accurately identify a mineral.

The noose is the loop at the end of the rope which is placed around the victims neck, the actual rope is known technically as a ligature and the gallows is the platform.

Hematite and magnetite are the primary minerals used to create iron ore through the process of extraction and refining. These minerals contain a high concentration of iron, which is extracted and processed into iron ore for various industrial applications such as steel production.

The value of iron pyrite can vary depending on quality and market demand. On average, it can range from $1 to $10 per pound. So, for 16 ounces (1 pound), the value could be anywhere from $1 to $10.

A barometer shows a greater reading when taken into a coal mine because the air pressure is higher underground due to the weight of the earth's atmosphere above it. This increased pressure causes the barometer to indicate a higher reading.

Minerals like uraninite and carnotite are highly radioactive ores of uranium.

From 1000 g of ore containing 1 percent metal, you would be able to extract 10 g of metal. This is calculated by taking 1 percent of 1000 g.

The Chilean miners were mining for copper at the San Jose copper-gold mine in Copiapo, Chile. Copper is a valuable metal used in various industries like electronics, construction, and transportation.

The most common ore in iron is hematite (Fe2O3).

First, the ore must be mined from the ground. Next, it needs to be processed to extract the desired minerals from the ore. This is typically done through crushing, grinding, and separating the ore. Finally, the extracted minerals are further refined and processed to create the final product.

One of the biggest problems for miners is ensuring the safety of their workers in often hazardous conditions underground. Additionally, fluctuating commodity prices and market demand can also pose challenges for miners in terms of profitability and sustainability. Lastly, environmental concerns related to pollution and land degradation from mining activities are significant issues that miners need to address.

Density is used to separate gold from surrounding material because gold is much denser than most other minerals and rocks. By exploiting this difference in density, it becomes possible to use techniques such as panning, sluicing, or shaking tables to effectively separate gold from the lighter materials it is often found with. This enables efficient recovery of the valuable gold particles.

ROCKS USED FROM THE EARTH'S CRUST

We get lots of different types of rock from the earth's crust, such as gems building material and ores. Ores such as lead gold and manganese are used to make coins. Gems, for instance diamonds, rubies and sapphires, can be carved and used in rings necklaces and earrings. Carbon fuels like coal peat and oil are flammable materials from the earth's crust. There are different types of rucks used from the earth's core for example brick, sandstone and limestone are used for building houses. Quartz is used for making clocks and chalk is used for writing.

We also get gravel and granite from the Earth's crust. Granite is used for countertops in kitchens, bathrooms, etc. We dig and mine gravel. Gravel is used for driveways and in some parking lots. It looks like little pieces of rock.

Farming typically takes place in the Central Lowlands of Australia due to the fertile soils and sufficient rainfall for agriculture. Mining activities are less common in this region compared to other parts of Australia.

Amethyst can form over tens of thousands of years as silica-rich water containing traces of iron seeps into cavities in rocks, where it slowly crystallizes and builds up to create amethyst crystals. The exact time can vary depending on environmental conditions and the specific geological processes involved.

Ore is processed to extract valuable metals or minerals from it. The processing removes impurities and separates the desired materials for further refining and utilization in various industries such as manufacturing, construction, and electronics. This process helps in making the most out of natural resources and meeting the demands for these materials in the market.

Realgar is an orange-red mineral used in pyrotechnics and as a pigment for tanning.

Tin is separated from tin ore through a process called smelting, where the ore is heated with carbon in a furnace to create tin metal. This process allows the tin to be separated from the other impurities in the ore, resulting in pure tin metal.

Yes. There is an enormous amount of mineral resources in the Himalayas. Mining has been occurring there for centuries and then transported all over the world through the Great Silk Road. One of the royal crowns has a Spinel (ruby) the size of a golf ball that was mined from the Himalayas. Due to the extremely rough terrain, modern mining has been kept to a minimum in Nepal and Bhutan which lack the infrastructure and financial resources required for large operations. Many outside companies have tried setting up shop there but few have worked out. Another thing limiting the mining in Nepal and Bhutan has been the importance placed on not impacting the environment which is ingrained in their Tibetan roots. They mine for; Iron, Limestone, numerous rare gems (some found only in the Himalaya), Granite, Dolomite, and many others

India has the largest reserves of thorium in the world, followed by countries like Australia and the United States. Thorium is a naturally occurring radioactive element that can be used as a fuel in nuclear reactors.

mafic because it is-dark colored. Ultramafic - no light colored mineral which means it it attracts most heat from a volcano taking it longer to cool down from the lighter, in between substance known as felsic :D

Gallium is not found free in nature, and it is present in only ppm (parts per million) quantities in minerals. For that reason, we recover gallium (III) salt as a byproduct of bauxite (a chief ore of aluminum) and sphalerite (a primary ore of zinc) processing. In either case, gallium chloride (GaCl3) is the salt we generally extract. Recovery of gallium from other sources is negligible. Use the link below for more information on this interesting poor metal.

China is the largest producer of neon in the world. The country accounts for a significant portion of global neon production due to its large chemical industry and manufacturing sector.

I can't bother to write the right answer, so this is it:
