iron ore processing vs recycling
Energy Efficiency and Recycling: Start with Recycling Scrap Metal
In fact, recycling scrap steel uses 75 percent less energy to process than iron ore, while recycling aluminum uses 95 percent less energy. It's been estimated, in fact, that by recycling a single aluminum soda can, enough energy gets saved to power a 60-watt light bulb for four hours.

Iron Ore Sintering: Process: Mineral Processing and Extractive
16/02/2017Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents, and solid fuel (coke). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.
