Prospect of commercial production of ferro-nickel production in India

摘要

The most important use of nickel is in steel industries where bulk of it or nickel in alloy form is required for the production of stainless steel. The country imports ferro-nickel as there is no viable process to produce ferro-nickel from the internal resources. looking into the country's import of nickel to meet its requirement, efforts have been made to produce ferro-nickel from the workable deposit lateritic ores or chromite overburden in Sukinda region, Orissa. The lateritic ore or Chromite overburden materials is reduced by pan sintering technique followed by magnetic separation and the smelting of magnetic fraction to produced ferro nickel. The smelting studies have been carried out using various amount of reductant and it has been possible to produce Fe-Ni of grade varying from 4 - 25% Ni.
