RASA Plant — 30 TPH Chrome Tower Plant, Built and Operated
Project Overview
Black Mountain Minerals delivered the RASA plant end to end: full site development, plant construction, and six months of continuous operation.
The scope covered everything from bare ground upward — water storage dams, civil works and foundations, site infrastructure and electrical supply and reticulation, followed by the design, fabrication and erection of a 30 TPH chrome tower plant. All structural steelwork was fabricated, sandblasted and coated in-house at BMM's Brits facility. The build was completed in four months, with production starting immediately on handover to operations.
BMM then operated the plant and processed the material itself, taking the project through to saleable chrome concentrate rather than handing over at commissioning. The plant ran 24 hours a day, six days a week, with Sundays reserved for planned maintenance, sustaining that cycle across a six-month campaign.
The circuit is a four-stage gravity spiral configuration — roughing, middling, cleaning and re-cleaning — producing multiple chrome concentrate grades in a single pass with no chemical intervention.
Key Outcomes
- Turnkey delivery — site development, civils, dams, power and plant under one contract
- Bare ground to production in four months, with no gap between construction and operation
- Full electrical infrastructure and reticulation installed by BMM
- Four-stage spiral circuit: roughing, middling, cleaning, re-cleaning
- Multi-grade chrome concentrate output without chemical reagents
- Operated by BMM for six months on a 24-hour, six-day cycle with planned Sunday maintenance
- All steelwork fabricated, sandblasted and coated in-house at Brits
