Dec 14, 2012 iron extractionraw materials, furnace, reactions taking place, collection of iron, memory technique to remember the entire process.Inquire now extraction of iron, iron extraction process, iron ore the extraction of iron is based on magnetic difference of iron ores.
Leaching offers an alternative to copper mining.First, the ore is treated with dilute sulphuric acid.This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate.The copper is then recovered by electrolysis.This process is known as sx-ew solvent extractionelectrowinning.Read More
