Ore extraction After a mining company has removed overburden, extraction of the mineral ore begins using specialized heavy equipment and machinery, such as loaders, haulers, and dump trucks, which transport the ore to processing facilities using haul roads. This activity creates a unique set of environmental impacts, such as emissions of

· Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times. Prehistoric people first mined flint, which was ideal for tools and weapons since it breaks into shards with sharp edges.

· The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.

Mine rehabilitation is an essential process for the ecological recovery of the mined area. It aims to minimize and mitigate the environmental effects of modern mining. In other words, its goal is to accelerate natural successional processes in order to increase biological productivity, reduce rates of soil erosion, increase soil fertility and biotic control over biogeochemical fluxes within ...

The Sigatoka iron sand mineralisation is easily accessible and mining is expected to employ lowcost dredging methods commonly used in the mineral sand mining industry. The magnetite and other heavy minerals of value are recovered as concentrates by various combinations of gravity, electrostatic and magnetic processes that are already widely used in the mineral sands .

The size of the chunks is important because the miners don't normally want it in minute pieces. They usually want it in pieces that are capable to be moved with big machinery. This mining is done in elongated, narrow strips. When the ore is done in one strip, the miners start to create another strip next to it.

· The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps. The first is discovery of the iron ore deposit which is carried out through prospecting or exploration to find and then define the extent, loion and value of the ore body.

For a time, the sand and the dust left behind by mined waste rocks left a footprint on the land. It prevented any crops from being grown and essentially ‘killed' the area. One way to do this is to mine the waste rocks for any further minerals. Whilst it increases the efficiency of the mining process, there are economic questions to answer.

March 3, 1999: A metalmaking process known to the ancient Romans could be pressed into service to bring Mars into the Iron Age and start opening the solar system to human habitation. "If you look at the soil composition of Mars, the one thing that really strikes you is that it's 5 to 14 percent iron oxide," said Dr. Peter Curreri, a materials scientist at NASA's Marshall Space Flight Center.

· Miners segregate heavy minerals from sands and ore deposits to produce coltan (columbite and tantalite mineral) and tantalite, and stock at home sometimes significant quantities of these minerals. Because these contain also uranium and thorium series radionuclides, miners and their families expose themselves to significant radiation doses (Carvalho et al. 2014b ).
