additional recovery of 3.697% of the original analyte; and the third sequen- tial extraction produces further recovery of 0.142% of the original analyte, for a cumulative recovery after three sequential extractions 3 50 ml of 99.993%.
the jee main syllabus is out and we figured that iron extraction is a very important topic when it comes to chemistry. keeping that in mind, we are here with a detailed explanation of the concept. the extraction of iron from its ore is the third and the penultimate process in metallurgy, which is the process of separating metals from their ores.
extracting iron here i use a gentle supply of oxygen at the surface of the reaction mixture to generate the high temperatures >1000ºc necessary for the direct reduction of iron oxide with carbon. 1 the resulting sparks, smell and bright light make for a dramatic demon-stration, and the resulting lump of iron can be handled when cooled.

extraction of iron step1: concentration the ore is crushed in crushers and is broken to small pieces. it is concentrated with gravity separation process in which it is washed with water to remove clay, sand, etc. 8. steps of extraction step1: concentration step2: calcination the ore is then heated in absence of air calcined .
for the iron tablet extraction, the second part of the experiment, an iron tablet and 20 ml of 5 m hno 3 was placed into a 25ml flash and heated on a hot plate. after 10 minutes, the tablet was crushed and heated for another 10 minutes.
the iron product, which may be completely free from zinc and other impurities, will be an iron salt or iron oxide, depending on the stripping procedure. in the following, each of the three operations, the organic leach, the solvent extraction, and the stripping will be discussed and described in more detail.
the total content of iron was determined by the technique of atomic absorption spectrometry, which allowed for the determination of iron content in organic and inorganic complex compounds. detection limits of 1 mg kg 1 were obtained for all determined iron forms, with the precision ranging between 0.7 % and 1.5 % for 10 mg kg 1 concentration.
