  • Process For Smelting Ferronickel By Rotary Kiln

    The complete process of smelting is: dry ore and bulk crushing → coal blending and flux into the rotary kiln, thorough drying and pre-reduction → reduction furnace smelting → ferronickel Hot metal ingot and slag water quenching → produce nickel iron ingot (or water quenched into nickel iron particles) and water quenching residue.

    Ferronickel an overview ScienceDirect Topics

    The smelting of ferronickel using lean nickel ores usually starts with roasting (calcining) of the ore mixture with limestone (~one third of the ore), anthracite (~1/10 of the ore amount), and recycled dust. Roasting is carried out in rotary kilns (~3 m in diameter, ~75 m in length, with a hot zone length of 9 to 12 m in the case of lean ore processing).
