SELECTION OF IRON ORES The iron ores are taken out or extracted from earth by mining operations, While selecting the site for such mines, the following points should be carefully examined: 1. The iron ores available from mines should be rich in metallic iron content. For ores containing less percentage of metallic iron, considerable amount of coke and flux will be required and it will not be economical to manufacture iron from such ores. 2. The mines for the iron ores should be located suitably in both ways, geographically and geologically. By geographical location, it is meant that the mines should be easily accessible and they should be linked up with surrounding towns by suitable transport facilities. By geological location, it is meant that site for mines should not contain conditions which might develop complications in quarrying and mining operations. 3. The composition of gangue or substances associated with ore should also be carefully studied. Some substances are such that t
