Overview of innovation

The invention relates to a novel process of partial oxidation of un-agglomerated chromite ore in ferrochrome production processes.

The process includes the steps:

  1. providing a source of un-agglomerated chromite ore;
  2. subjecting the source of un-agglomerated chromite ore to pre-oxidation at a temperature of 700 °C to 1100 °C, both values inclusive;
  3. controlling the above-mentioned pre-oxidation temperature such that maximum migration of iron (Fe) to the surface of the chromite ore particles takes place and minimum Cr2O3 formation takes place; and
  4. forming a pre-oxidized source of un-agglomerated chromite ore wherein maximum migration of iron (Fe) to the surface of the chromite ore particles takes place, as well as minimum Cr2O3 formation.

Market Opportunity;
The process is capable of achieving significant reductions in specific electricity consumption during ferrochrome production processes. This would have a clear effect on the bottom line of smelter operations.

Technology benefits
Significant reduction in electricity consumption and costs.
