PROCESS FOR SIGNIFICANT ELECTRICITY COST SAVINGS IN FERROCHROME PRODUCTION
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:
- Providing a source of un-agglomerated chromite ore;
- subjecting the source of un-agglomerated chromite ore to pre-oxidation at a temperature of 700 °C to 1100 °C, both values inclusive;
- 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
- 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.
