How minerals recovered or extracted from their ores?
The methods used to extract minerals from ores vary; each ore has its own suitable method(s) of extraction. For example, iron can be extracted from its ore through the blast furnace method, while more reactive minerals (such as aluminum) may need to be extracted through electrolysis.
What kind of surface or subsurface mining was done in Leadville Colorado?
In Leadville, Colorado, both surface and subsurface mining were conducted. Surface mining involved open pit mining for materials like gold and silver. Subsurface mining involved digging shafts and tunnels deep underground to extract minerals like lead and zinc.
What is the world's chief diamond mining center?
The world's chief diamond mining center is Botswana, particularly at the Jwaneng and Orapa mines. Botswana is one of the world's top diamond producers, known for its high-quality diamonds and efficient mining operations.
How can people obtain water from an aquifer?
People can obtain water from an aquifer by drilling a well into the ground until it reaches the water table of the aquifer. A pump is then installed to lift the water to the surface for use. Proper management and monitoring of groundwater extraction is essential to ensure sustainable use of the aquifer's water resources.
A tornado can cause destruction by uprooting trees, damaging buildings, and throwing debris at high speeds. It can also result in injuries and fatalities due to its strong winds and flying objects.
The study of rocks is called petrology. It involves examining the composition, structure, and formation of rocks to understand their properties and geologic history. Petrologists use various techniques such as microscopy, chemical analysis, and field observations to study rocks.
On which continent is the deepest point on land?
The deepest point on land is in Antarctica. It is called the Bentley Subglacial Trench, and it reaches a depth of about 8,200 feet below sea level.
What type of scientists that do the study of rocks are called?
Scientists who study rocks are called geologists. They specialize in the field of geology, which includes the study of the Earth's history, structure, and processes, including the formation and properties of rocks.
How is copper extracted from earth?
Copper is extracted from the earth through a process called mining. Open-pit or underground mining methods are typically used to access the copper ore deposits. The ore is then crushed, ground, and processed to extract the copper minerals through a series of physical and chemical processes.
How does sand get transported along a beach?
Sand gets transported along a beach primarily through longshore drift, where waves approach the shore at an angle and carry sediment parallel to the coastline. Additionally, tides and currents can also contribute to the movement of sand along a beach.
Quartz is a mineral primarily made up of silicon and oxygen. It is the second most abundant mineral in the Earth's continental crust and is commonly found in igneous, metamorphic, and sedimentary rocks.
How does coal mining harm the environment?
Coal mining has the following adverse effects on the enviroment:
Extraction of the coal causes the landscape to sink
Water is used to separate coal from stone which creates lots of dirty water.
Deep mining requires vast amounts of contaminated water to be pumped out of the workings
The waste solid material separated from the coal has to be disposed of.
Transportation of the excavated coal requires railway links.
Burning most types of coal can result in more air pollution (Carbon dioxide (CO2) causing global warming and climate change) than any other type of fossil fuel.
Pollution with coal powders of the environment; coal burning release carbon dioxide, nitrogen dioxide, sulfur dioxide, flying ash.
How far below the surface are the chilean miners trapped?
They are nearly 625 meters below the surface with some of the toughest, hardest rock in the world between them and daylight. The escape hole was completed on Saturday the 10/10/10 (John Lennon's 70th Birthday) with much of the credit going to the skill of a 40 year old American, Jeff Hart.
"After the cave-in, engineers initially bored narrow shafts the width of a grapefruit to locate the men.
When they were found 17 days after the accident, all still alive, celebrations sprang up across Chile. Rescuers then passed high-energy gels, water and food down the narrow ducts to keep the miners alive".
Why was iron discovered before aluminum?
Iron was discovered before aluminum because iron is more abundant in the Earth's crust and has a lower melting point, making it easier to extract and work with. Aluminum, on the other hand, is typically found in compounds with other elements that made its extraction more challenging and costly until the 19th century when better extraction methods were developed.
Type of mining where passageways are dug underground to reach the ore?
This type of mining is called underground mining. Miners access the ore through tunnels and shafts dug beneath the surface of the Earth. It is often used when the ore deposits are located deep underground.
Name some problems involved with quarrying?
Noise pollution Visual Pollution Loss of habitat for wildlife Loss of farmland Quickly exhaust natural resources Destroy beautiful areas of karst landscape Dust pollution Pollution and lots of traffic because of lorries coming to collect the rock (this also furthers global warming) Wildlife will be driven away because of the noise and dust
What are the advantages and disadvantages of mining?
The advantage is that it supplies raw materials (metals, coal) that are needed to build and maintain modern industries and economies.
The disadvantages include:
Reasons for Mining
Gold, diamonds and ores such as uranium supply national governments with trading goods, and provide jobs for millions of miners.
Mining is essential to modern society. The computer you are using to read this contains about 37 materials that came from mining. The electricity to power it may come from coal, oil, or gas brought from underground.
A tornado effects the world, in many ways. Firstly, it can effect people, the environment, animals etc. Since a tornado is a really dangerous type of storm with all different kinds of harmful bacteria.
What was the Granduc Mine Disaster?
The Granduc Mine Disaster occurred on November 18, 1965, in British Columbia, Canada, when an avalanche struck the Granduc copper mine, killing 26 miners. The avalanche was triggered by heavy snowfall and unstable snow conditions. It remains one of the deadliest mine disasters in Canadian history.
How much money does a mining geologist make?
A mining geologist typically earns between $50,000 to $120,000 per year, depending on factors such as experience, location, and the specific industry they work in. Advanced degrees or certifications can also contribute to higher earnings.
Subsurface mining is a method used to extract minerals and ores that are located deep underground. It involves creating tunnels and shafts to access the deposits and extract the resources. This method is often used when the mineral deposits are too deep to be reached with surface mining techniques.
Can Fluoroantimonic acid burn through Iron ore?
Yes, fluoroantimonic acid is a superacid that is extremely corrosive and has the capability to burn through iron ore due to its strong acidic nature. When exposed to iron ore, fluoroantimonic acid can react with the iron present in the ore, leading to dissolution and corrosion of the material.
Where are limestone-micrite rocks found?
Limestone-micrite rocks are typically found in shallow marine environments, such as platform carbonate settings or coastal lagoons. They form from the accumulation of fine-grained carbonate mud that becomes lithified over time. These rocks are commonly associated with sedimentary environments that have low energy conditions and high amounts of organic matter.
Fluid mining is extracting the metals from hydrothermal fluid vents from under the ocean. The "Smoke" coming out of these vents are actually very high in metal, especially gold, silver, copper, and zinc. To do this, you pump the fluid into a kind of "Metal extraction" device. There are a few problems, though, such as the such high temperature of the fluid, and how to keep the fluid from clogging up the device.
What do diamonds look like when they come out of the ground?
Diamonds come out of the ground looking like rough, unpolished crystals. They may appear cloudy, dull, and in various shapes such as octahedral or cubic. The raw diamonds have a rough texture and must be cut and polished to reveal their natural sparkle and beauty.
