Application of CSC Technology in Nonferrous Metallurgy
205
(3) Furnace Top and Uptake
The furnace top is lined with refractory coating of steel water jacket, and it is provided
with a charging opening and an uptake flue surrounded by membrane wall.
Typical Cases of Industrial Application of CSC Technology
Process Copper-Nickel Ore to Produce Low-Grade Matte
Nickel [1]
(1) Typical case: Oxygen-enriched Air Side-blown Smelting Project of CopperNickel Ore of a Plant in Xinjiang.
(2) Design capacity: Granulated metalized high-grade matte nickel (nickel metal
content); 8000 t/a.
(3) Main process: Copper-nickel ore is used as the main raw material, and CSC
oxygen-enriched air side-blown bath smelting-depleted electric furnace slag
depletion-PS converter blowing technology is adopted to produce granulated
metalized high-grade matte nickel, please refer to Fig. 2 for process flow. It was
put into operation in March 2011, with good operation effect. It is the first time
that China to apply this process to treat copper-nickel ores.
