The Nzema Gold Processing Plant, located in Ghana, is a state-of-the-art facility designed to extract and refine gold ore efficiently. As a professional in the crushing and sand-making equipment industry, understanding the plant’s core processes and equipment requirements is crucial for optimizing production lines and ensuring high-quality aggregate output.
The gold processing line at Nzema typically includes crushing, grinding, gravity separation, flotation, and cyanidation. Below are the key equipment and their roles:
1. Primary Jaw Crusher: Breaks down large gold-bearing rocks into smaller chunks (150–300 mm).
– Model: PE-600×900
– Feed Size: 500 mm
– Capacity: 50–160 t/h
2. Secondary Cone Crusher: Further reduces ore size to 25–60 mm for grinding.
– Model: CS160
– Output Size: ≤38 mm
– Capacity: 120–340 t/h
3. Ball Mill: Grinds crushed ore into fine powder (<0.074 mm) for separation.
– Model: MQG2700×3600
– Capacity: 12–14 t/h
4. Spiral Classifier: Separates ground slurry by particle size.
5. Flotation Machine: Recovers fine gold particles through chemical processes.
| Equipment | Model | Feed Size | Output Size | Capacity | Power |
|——————–|——————|———–|————-|————-|————-|
| Jaw Crusher | PE-600×900 | ≤500 mm | 65–160 mm | 50–160 t/h | 55–75 kW |
| Cone Crusher | CS160 | ≤230 mm | ≤38 mm | 120–340 t/h | 160 kW |
| Ball Mill | MQG2700×3600 | ≤25 mm | ≤0.074 mm | 12–14 t/h | 400 kW |
Project: Nzema Gold Plant Expansion (2022)
Challenge: Low gold recovery rate due to inefficient grinding.
