Environmental Guidelines For Nickel Smelting And

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

A Process For Direct Stainless Steel Production From

May 01 1987 After the nickel oxide ore blended with high-iron-content nickel ore is dried with a rotary dryer and crushed with an impeller breaker it is mixed with coal as a reductant and fed into the kiln. In the kiln the ore is calcined and pre-reduced Ni reduction ratio 80 Fe reduction ratio 60 and then hot- charged at a temperature of about 1000 into the 60000 KVA closed electric smelting furnace.

The process works best when the ore is crushed to small pieces before roasting. Additives such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted and the sulfur is driven off the extraction of the gold or silver from the ore is not especially difficult.
