primary copper and nickel is produced using Outotec's proprietary process. The process is highly energy efficient because it makes full use of the reaction heat of the concentrate, meaning that no external fuel is required for smelting. The high sulfur capture rate of more than percent is achieved by using lowvolume process gas, a compact layout, and a sealed furnace. For these .

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.
