(D) The process of removing gangue from an ore is known as concentration or dressing of ore. Common methods for concentration include Froth flotation,Magnetic separation,and Centrifugation (or Gravity separation). Calcination is a process used in the extraction of metals from concentrated ore,where the ore is heated strongly in the absence of air to convert carbonates into oxides. Therefore,Calcination is a metallurgical process used for refining/extraction,not for the concentration of ore.
