Small centrifugal concentrators are compact, high-efficiency devices designed for gold recovery in both hard rock and placer mining operations. These units leverage centrifugal force to separate heavy minerals like gold from lighter gangue materials, achieving recovery rates of up to 99% for particles as fine as 20 microns.
| Model | Capacity (t/h) | Power (kW) | Weight (kg) |
|---|---|---|---|
| CC-100 | 0.5–1.0 | 1.5 | 85 |
| CC-200 | 1.0–2.5 | 3.0 | 120 |
| CC-300 | 2.5–5.0 | 5.5 | 180 |
These concentrators integrate seamlessly into:
– Crushing-Screening-Grinding Circuits: For hard rock gold ores post-crushing/grinding.
– Alluvial Wash Plants: As final recovery units after trommels or sluices.
While primarily for gold, centrifugal concentrators also recover heavy minerals (e.g., hematite) in sand/gravel plants, improving product purity and reducing waste disposal costs.

Q: What’s the minimum particle size recoverable?
A: Down to 20 microns with optimized feed density (~25% solids).
Q: Can it handle sulfides?
A: Yes, but pre-oxidation may be needed for refractory ores.
