  • Flash Smelting Process Outotec

    The Outotec Flash Smelting Process is one of the world’s most commonly used processes for the production of primary copper and nickel. The process is based on our flash smelting principle, which utilizes the internal energy of the feed material for smelting, minimizing the need for external fuel and making the process very energy efficient.
