Answer» Correct Answer - d The iron ores contain`20% and 65%` of iron , the chief impurities silaca and alumina Both have such high melting points that they would not melt in th eblast furnac but would form an ash which would have to be removed mechenically to overcome this diffetlity become into calcium oxide, which combinas with the silica ab=nd alumina , removing then as a fusible slag . `CaO+SiO_(2) rarr CaSiO_(3)`
