Question

Name the methods for concentration of ore

The ore has higher density particles interspersed with a large bulk of lower density materials

Answer 1

• The gravity separation method is the method that is used in concentrating this ore.
• The gravity separation method is used to concentrate Hematite ore.
• ${\mathbf{Fe}}_{\mathbf{2}}{\mathbf{O}}_{\mathbf{3}}$ is the chemical formula for Hematite.
• The hematite ore particles are first crushed to a fine powder and then concentrated via gravity separation.
• The powdered hematite ore is washed away by an upward stream of flowing water during the process.
• And the lighter particles are washed away by water.
• The ore particles that are heavier are left behind.
