Iron ore: Confounding the expectations of experts | Edison

So far, iron beneficiation appears to be a mostly mechanical process, but with flotation it becomes a chemical one. In flotation, chemicals are mixed with water and crushed ore. The chemicals make minerals hydrophobic (unable to adhere to water), but allow them to attach to bubbles formed by a (chemical) frother.
