As a major global chrome ore producer, South Africa’s chrome resources are mainly distributed in the renowned Bushveld Igneous Complex. The ores in this region are predominantly massive and densely disseminated, with a Cr₂O₃ content typically ranging from 40% to 50%. Based on the properties of South African chrome ore, we have designed a rational 50tph chrome ore beneficiation process (chrome washing plant) for our South African customers.
For a 50 tons per hour chrome ore washing and processing capacity, we have provided our South African customers with a complete equipment configuration plan that balances reliability, cost and separation efficiency. The main equipment list is as follows:
| Process | Core Equipment | Model | Function |
|---|---|---|---|
| Crushing | Jaw Crusher | PE600×900 | Responsible for the primary crushing of large raw ore, reducing the material to below 100–150 mm. |
| Cone Crusher | CSB240 | Performs secondary and tertiary crushing; closed-circuit circulation ensures the discharge size is ≤12 mm. |
|
| Circular Vibrating Screen | 3YK2460 | Screens the crushed materials; oversize material is returned to the cone crusher for re-crushing. |
|
| Grinding & Grading | Rod Mill | Ф2700×4000 | Grinds materials ≤12 mm to 0.5–1 mm with minimal over-crushing. |
| Ball Mill | Ф2700×3600 | Conducts fine grinding in closed circuit with a classifier, reducing rough concentrate to –0.3 mm or finer to achieve mineral liberation. |
|
| Spiral Classifier | Ф2000 | Works in conjunction with the ball mill to separate qualified-size slurry; coarse sand is returned for re-grinding. |
|
| Classification | Spiral Chute | 5LL-1200 | Used for roughing and scavenging, achieving preliminary concentration based on density difference with a recovery rate of over 50%. |
| Shaking Table | LY4000 | Performs cleaning to further upgrade the spiral chute concentrate, producing high-grade chrome concentrate. |
|
| Magnetic Separator | CTB1024 | Removes impurities and upgrades the concentrate by eliminating weakly magnetic gangue minerals, improving concentrate purity. |
|
| Dewatering | Gravity Thickener | NMJ20 | Provides preliminary sedimentation and dewatering of the concentrate, reducing the load for subsequent drying. |
| Rotary Drum Dryer | RD24 | Conducts thorough drying to produce final chrome concentrate powder with qualified moisture content (typically <5%). |
Summary: Chrome ore beneficiation process consists of a complete set of procedures including crushing, grinding, classification, separation and dewatering. Each procedure is equipped with corresponding equipment. Proper selection of beneficiation equipment can achieve maximum economic benefits.
