The gravity separation technique is used to concentrate hematite ore. Iron oxide ore hematite is a common resource. Fe2O3 is the chemical formula for hematite. The ore of hematite is black or silver-grey in colour. The hematite ore particles are first crushed to a fine powder, then concentrated via gravity separation. The powdered hematite ore
