    She's "a fieldie" working with the iron ore drill rigs She shares how iron ore is found She explains how the drill goes down a set distance, for example 30m, and collects a sample every half a metre She tests the sample of soil to see if the sample is waste or ore by scratching the surface to look at the colourIron ore was won by drilling and blasting ( Figure 71 ) As mining technology generally developed, so did drilling techniques and the explosives used Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as “dogger”) allowing mine drivages to be selfsupportingIron ore extraction techniques ScienceDirectdrilling methods for iron ore 4chefspl drilling for iron ore magazene Environmental impact of iron ore mining Wikipedia The environmental impact of iron ore mining, in all its phases of,, Common methods of extracting the iron ore consist of blasting, drilling, or general excavating,,, Iron ore mines are projects with activities branching off into most aspects of ecologydrilling methods for iron ore analizainstytucjipl

  • Geology, Prospecting and Exploration for Iron Ore

    There are two main methods of exploratory drilling namely core drilling and percussion drilling Core drilling, yields a solid cylinder shaped sample of the ground at an exact depth Percussion drilling yields a crushed sample, comprising cuttings from a fairly well determined depth in the holeHow is iron extracted from its ore? Iron is concentrated by the process of calcinations Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed This concentrated ore is then mixed with limestone (CaCO 3) and Coke andIron Ore Mining | Techniques | Metal ExtractionThe gravity method was first applied to Fe ore exploration as a tool for detecting nonmagnetic ores, but advantages of this method over other exploration methods have also made it useful under certain geological conditions in the study of magnetic ores and regional structures favorable for the occurrence of Fe oreApplication of the gravity method to iron ore exploration
