·Iron ores are rocks and minerals from which metallic iron can be extracted The main iron ores are hematite and magnetite Hematite and magnetite are iron oxides that have been mined for centuries to produce steel and iron products There are different forms of processed iron pig iron has a high carbon content and is very brittle; wrought
·In contrast the remaining countries in general are mining less than their percentage of global reserves Iron ore is commonly transported to downstream metal extraction plants with minimum beneficiation because of their relatively high ore grades as mined typically 60% for iron ores from Australia
·India s iron ore production has just doubled in the last 5 years achieving a total of 154 MT in 2005 06 compared with 86 MT in 2001 02 The Indian iron ores in general and Eastern Indian iron ores in particular consist of various impurities in the forms of Al P and Si and this poses major beneficiation problems especially in fines
·The possible range of origins has to be taken into account in exploration particularly as regards the depth of drilling and in the characterisation of ores for metallurgical use Many high grade iron ores are considered to result from the supergene enrichment of banded iron formations The secondary processes may be related to either present
· Energy Rock drilling blasting and comminution crushing and grinding consume a vast amount of energy in hard rock mines As mentioned in Sect 1 statistics from hard rock mines indicates that drilling and blasting consumes 2% and comminution does 53% of the total energy input in the whole production chain from mining to mineral processing Spathis
4 ·Drilling Machine is a multiblock added by Create Ore Excavation used to obtain infinite ores Drilling Machine can be mined using at least iron pickaxes Like most Create Mod blocks it can also be sneak right clicked with a Wrench to pick up without using durability of tools If mined by other means it will drop nothing Drilling Machine can be crafted using 25 Mechanical
·The alternative employed ores were being investigated at different temperatures to realize their prospect to be employed as weighting agents in drilling mud technology [18] Solids content rheological properties and density of the analyzed samples were studied [19] An alternative obtained weighting material that be utilized in place of barite could be described as
·The drill bit is threaded onto the core barrel and attached onto a bottom of a hollow drill rod string Because of the opening at the end of the diamond bit Fig it cuts a cylindrical shaped solid column of rock called drill core Fig which moves up into the tubular drill rod pipe as drilling progresses of the drill bits includes a core lifter
·Therefore the iron ores were chemically precipitated from a mixture of seawater and hydrothermal fluids Two conservative end member mixing calculations indicate that the Eu/Sm Sm/Yb and Y/Ho ratios of the Gongchangling iron ores can be accounted for by % high temperature hydrothermal fluid mixed with seawater Fig 10
