H ow we get coal Mining the Coal . Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many U.S. coal beds are very near the ground's surface, and about two-thirds of coal production comes from surface mines.
What is mining? Mining is the extraction (removal) of minerals and metals from earth. Manganese, tantalum, cassiterite, copper, tin, nickel, bauxite (aluminum ore), iron ore, gold, silver, and diamonds are just some examples of what is mined.
Mining is the process of taking things from the ground. Any material that cannot be grown must be mined. Mining things from the ground is called extraction.Mining can include extraction of metals and minerals, like coal, diamond, gold, silver, platinum, copper, and iron.Mining can also include other things like oil and natural gas.. Some mining is done by scraping away the soil (dirt) from the ...

In solution mining, wells are erected over salt beds or domes (deposits of salt forced up out of the earth by tectonic pressure) and water is injected to dissolve the salt. Then the salt solution, or brine, is pumped out and taken to a plant for evaporation.

Mining iron ore is a high volume low margin business, as the value of iron is significantly lower than base metals. It is highly capital intensive, and requires significant investment in infrastructure such as rail in order to transport the ore from the mine to a freight ship. 
Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
Beyond the Iron: Mining Webinar series Success in today's environment requires more than the industry's best mining equipment. It requires solutions—and partnerships—that extend well beyond the iron.
Scientific American is the essential guide to the most awe-inspiring advances in science and technology, explaining how they change our understanding of the world and shape our lives.
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Iron ore refining process uses heat and another substance, so that oxygen molecule can bond to them and separate from iron. Carbon readily bonds with oxygen and so coal or coke (a form or carbon ) is used in the iron ore refining process.
