Chromite ore is predominantly used in ferrochrome production – an alloy of chrome and iron containing between 50% and 70% chromium. Steel production is the largest ferrochrome consumer, especially stainless steel production, which contains 10% and 20% ferrochrome content.
The process of chromite ore mining can be divided into two areas:
- Feed preparation
- Concentration
The feed preparation stage involves introducing various physical separation equipment, including crushers, screens, and grinding mills. The principal function of this stage is size reduction in preparation for the concentration phase.
The concentration phase introduces hydrocyclone technology and spirals to produce the chrome concentrate from which the final product will be derived. The wastewater from this process will report to tailings dams where an additional filtration stage may be employed.
We offer a range of equipment for the processing of chromite ore:
- Screening
Our Infinity screens can be employed to classify chromite ore in preparation for the further stages of processing. - Hydrocyclones
Our hydrocyclone technology can be employed to remove unwanted fines from your chromite ore before the material being stacked before the heap leaching process. - Log washers
Our RotoMax log washer is suitable when processing chromite ore with clay contamination. The log washer’s scrubbing process facilitates the breaking down and effective removal of these clays from your chromite ore, introducing efficiencies to downstream processes. - Tailings management
The move to zero tailings is facilitated by the specification of a customized filter press, which reduces waste and ensures a significant reduction in health & safety risks.
