Some gold can be found by panning in rivers heavy gold will remain in the pan whereas lighter rocks and minerals float out This small scale form of gold mining has little effect on the body of water but the large scale practice of mining gold from ore can have tremendous negative effects on water qualityMining 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 and processing Common methods of extracting the iron ore consist of blasting drilling or general excavating Most iron ore is produced from open pit min After the iron ore is out of the ground it may be shipped to the iron and steel manufacturing plantOpen pit mining where material is excavated from an open pit is one of the most common forms of mining for strategic minerals This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations which increases the amount of ore needed to be mined
