Production of Ferronickel from Spent Nickel Catalyst
Implementing Organization
National Metallurgical Laboratory (NML)
About
The main use of ferronickel is in the manufacture of steel.
Outcome / Output
It is a simple smelting process for recovery of nickel as ferronickel of various grades from different nickel catalysts containing nickel in the range, 8 -18%, By controlling the parameters and the process techniques, ferronickel of 20 - 75% Ni grade have been produced with 90% Ni recovery, The slag generated is non-toxc and can be dumped.
