Environmental Guidelines for Nickel Smelting and Refining
Sulfidic ore processing Modern technology uses electric smelting or flash smelting. Flash smelting is the most common process but electric smelting is used for more complex raw materials when increased flexibility is needed. Both processes use dried concentrates. Electric smelting requires a roasting step ahead of the smelter to reduce sulfur content and volatiles. .
