• ## Biological based approaches for iron removal from mining

All these elements are mined as a byproduct of base metals mining or other processes There is large presence of these metals in the waste generated by Zinc mining and Copper mining in both India and Australia However, the recovery of these metals is impeded by the presence of 100 – 1000 times excess iron present in them So far, there is no technology present to remove iron from theseIronHydroxideRemoval from Mining Affected Rivers Felix Bilek 1, Felix Moritz 1, Sören Albinus 2 1 DGFZ Dresdner Grundwasserforschungszentrum eV, Meraner Str 10 01217 Dresden, Germany, 2 LMBV Lausitzer und Mitteldeutsche Bergbauverwaltungsgesellschaft mbH, Knappenstr 1, 01968 Senftenberg, Germany, Abstract Oxic and ferricIronHydroxideRemoval from Mining Affected RiversThe occurrence of iron in water can also have an industrial origin ; mining, iron and steel industry, metals corrosion, etc In general, iron does not present a danger to human health or the environment, but it brings unpleasantness of an aesthetic and organoleptic nature Indeed, iron gives a rust color to the water, which can stain linen, sanitary facilities or even food industry productsIron removal by physical chemical way Lenntech

01/02/2009· The bioleaching of iron oxides by Aspergillus niger resulted in removal of 47 70% of the total iron in the quartz sand, and suggested that this strain has not a good ability to remove iron impurities from quartz sand in comparison with chemical leaching The iron content decreased from 0315% Fe2O3 to 0164% Fe2O3 in the bioleached quartz sandWrought iron is the purest form of iron available commercially available and is prepared from cast iron by heating cast iron in a furnace lined with Haematite (Fe 2 O 3) The Haematite reacts with Carbon in the cast iron to give pure iron and carbon monoxide gas which escapes $$Fe{2}O{3}+ 3 C \rightarrow 2Fe + 3 CO$$ Limestone is then added as flux, and it createsExtraction of Iron | Metallurgy | Blast Furnace and ReactionsSteel making and mining Separation of steel materials and collection of iron in residues Machine, press, plant Treatment of scraps and collection of ﬂ ux Food, candy, can making Removal of iron from raw materials and foreign matter in manufacturing processes Pulp, paper, stone crushing Removal of iron from raw materials and protection of crushers Chemicals Removal of ironMAGNETIC SEPARATORS

• ## Iron ore Wikipedia

Mining iron ore is a highvolume, lowmargin business, as the value of iron is significantly lower than base metals It is To convert it to metallic iron it must be smelted or sent through a direct reduction process to remove the oxygen Oxygeniron bonds are strong, and to remove the iron from the oxygen, a stronger elemental bond must be presented to attach to the oxygenOpen pit mining initially involves the removal of soil and rock on top of the ore via drilling or blasting, Openpit mining is probably most advanced because of developments in mining lowgrade copper deposits and iron ore It is suitable for much of the resource if it is done on a large scale and will allow lowcost removal of most of the resource Research needs include studiesOpen Pit Mining an overview ScienceDirectSteel making and mining Separation of steel materials and collection of iron in residues Machine, press, plant Treatment of scraps and collection of ﬂ ux Food, candy, can making Removal of iron from raw materials and foreign matter in manufacturing processes Pulp, paper, stone crushing Removal of iron from raw materials and protection of crushers Chemicals Removal of ironMAGNETIC SEPARATORS kaneteccojp

Mining The ore is removed from the ground in either open pit or underground mines Underground – sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore Openpit – 90% of ore is mined using the open pit method Ores near the surface can be quarried after removal of the surface layers The ore
