Abstract:
Gipronickel Institute is developing a brand new process of Buruktal Deposit nickel oxide ore treatment to ferronickel based on Vaniukov Furnace smelting technology. The new process based on Two-zone Vaniukov Furnace smelting has been proposed for treating saprolite ore of one of the largest in Russia Buruktal Deposit. The process flow-sheet is as follows: Ore crushing and drying-Briquetting-Roasting of briquettes in Tubular Rotary kiln-Smelting of hot briquettes in Two-zone Vaniukov Furnace to Ferronickel and dump slag - Refining of ferronickel Ladle-type Furnace. The paper presents the new process flow-sheet laboratory and pilot testing results. Technological peculiarities of the processes taking place in the furnace smelting and reduction areas are considered.
