Production Process
Ferronickel alloys
(Ferronickel = Steel and nickel alloys)
- ①Raw materials process
-
Pre-processing makes it easier to extract ferro-nickel from nickel ore and recycled raw materials.
- ②Smelting process
-
Ferro-nickel is separated using heat and reduction.
- ③Sieving process
-
Ferro-nickel is extracted.
