Process Plant Design, Engineering and Construction
Black Mountain Minerals designs and builds mineral processing plants engineered for a specific orebody or waste stream. There is no standard model. Each plant begins with testwork on representative material, and the flowsheet, circuit configuration and throughput are derived from what that material is shown to require.
This matters because recovery is determined long before a plant is switched on. Two chrome deposits with the same head grade can demand entirely different circuits depending on particle size distribution, liberation and slimes content. A plant designed around the average case underperforms on both. BMM's approach is to establish the characteristics of the material first, then engineer to the point of highest recoverable value from that material.
Design, fabrication, construction and commissioning are delivered under one contract. Structural steelwork is fabricated, sandblasted and coated in-house at the Brits facility in North West Province, and the company operates its own crane and transport fleet for delivery and erection. Where a client prefers it, BMM will also operate the completed plant.
- Testwork-led flowsheet design — circuits derived from the material, not from a catalogue
- Gravity concentration circuits, chemical-free, configured to the liberation characteristics of the feed
- Plants engineered for run-of-mine ore, tailings and other waste streams
- Throughput sized to the resource and the client's production plan
- All structural fabrication, sandblasting and coating in-house at Brits, North West
- Civil works, electrical installation and erection delivered under the same contract
- Own crane and transport fleet for delivery and site erection
- Commissioning to design specification, with operator handover or continued operation by BMM
How a Plant Is Developed
| Stage | What It Delivers |
|---|---|
| 01 Characterisation | Representative sampling and testwork to establish head grade, mineralogy, particle size distribution and liberation characteristics. |
| 02 Flowsheet Design | A process route selected against the testwork results and the client's target product specification. |
| 03 Engineering | Detailed design, equipment selection and structural engineering, sized to the agreed throughput and site conditions. |
| 04 Fabrication | Structural steelwork fabricated, sandblasted and coated in-house at the Brits facility. |
| 05 Construction | Delivery, civil works, electrical installation and erection on site, using BMM's own crane and transport fleet. |
| 06 Commissioning | Circuit commissioning to design specification, with operator handover or continued operation by BMM. |
