Pig Iron Manufacturing ProcessHow are impurities in iron ore removed Answers

In the electric furnace production of pig steel from ore carbon in the product can be kept below 22 per cent and regulated to an extent by the amount of carbon charged without resulting in excessive loss of iron in the slag or in the production of a pig steel very high in impurities if a fair grade of ore is usedAfter iron ore is mined it is crushed into a powder then injected into a blast furnace Under the extreme temperatures the ore melts and since iron is more dense than the impurities it sinks to
