A typical banded iron formation consists of repeated thin layers (a few millimeters to a few centimeters in thickness) of silver to black iron oxides either magnetite (Fe 3 O 4) or hematite (Fe 2 O 3) alternating with bands of iron-poor shales and cherts often red in color of similar thickness and containing microbands (sub-millimeter) of iron oxides
Magnetite resembles a number of other metal ores but it is the only common mineral that exhibits magnetism So magnetism alone is sufficient to distinguish relatively pure magnetite samples It is more difficult to distinguish cases where magnetite is mixed with
Understandably the amount of mining activity and its associated negative environmental impact can be significantly reduced by extracting various minerals from the CCBs which are abundantly available in numerous ash ponds all over the US Developing beneficial use of CCBs have been a major focus of coal researchers for last several decades
Mining - Mining - Underground mining When any ore body lies a considerable distance below the surface the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive and underground techniques must be considered Counting against underground mining are the costs which for each ton of material mined are much higher underground than on the

Mining has had a large impact on environmental sustainability in South Africa and will continue to affect the area into the future Open-pit mining in mines like Kimberley have created large deep pits which grew wider and filled up with water during rainfall it can increase up to 20 metres at times with heavy rain An indirect effect of mining is the larger population increases strains in the
The entire Jharkhand area rich in minerals will now throw open for plunder and loot by these vested interests With the expansion of the mining activities land degradation air water and noise pollution will attain alarming proportions This will have serious economic impact
The environmental impact of iron ore mining in all its phases of Iron in ore iron is most commonly found in the form of magnetite (Fe 3 O 4) hematite (Fe 2 O 3) Most iron ore is produced from open-pit mines After the iron ore is out of the ground it may be shipped to
