The iron ore production has significantly expanded in recent years owing to increasing steel demands in developing countri However the content of iron in ore deposits has deteriorated and low grade iron ore has been processed The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking This chapter shows the status of the pelletizing process The most commonly available ore used in the extraction of Zinc is called Zinc Blende also known as Zinc Sulphide ZnS Historically extraction of zinc has been more difficult than extraction of other metals because at temperatures where metals such as iron typically begins to melt zinc is a gas
