Project Portfolio

The projects presented below represent a selection of commissioned washplants and mining services works — not an exhaustive record. Each project reflects the full scope of Black Mountain Minerals' in-house capability, from design and fabrication to delivery, erection and commissioning.

01
New Build Pilot Scale Chrome Relocatable

24 TPH Modular Pilot Washplant

Project Overview

This project involved the full design, fabrication and supply of a 24 TPH modular pilot chrome washplant — built to operate without any civil foundation works and deployable on standard road infrastructure using our own crane truck and trailer fleet.

The plant uses a multi-grade gravity spiral concentrator configuration incorporating rougher, scavenger and cleaner spiral stages, enabling the production of multiple chrome concentrate grades in a single pass without chemical intervention.

Commissioning was completed in a single mobilisation — a key delivery milestone for pilot-scale work where client downtime and site disruption must be minimised.

Key Outcomes

  • Plant delivered, erected and commissioned in single mobilisation
  • Multi-grade chrome concentrate output (rougher / scavenger / cleaner)
  • No civil works required — zero site preparation cost
  • Fully relocatable — crane truck and trailer deployment
  • All fabrication, sandblasting and coating completed in-house at Brits
  • Operational on first-day commissioning

New Build Commercial Scale Chrome Brits · North West Tolling Operations

100 TPH Commercial Washplant, Brits NW

Project Overview

This project represents Black Mountain Minerals' flagship commercial-scale chrome washplant — a 100+ TPH installation near Brits, North West Province, designed for continuous tolling operations processing third-party chrome ore against a production fee structure.

The plant was designed and built from first principles at our Brits fabrication facility, incorporating an incline conveyor feed system, a vibrating screen for pre-classification, dual-tier spiral banks across rougher and cleaner stages, and a full concrete slab foundation with integrated pump room and water recirculation infrastructure.

The dual-tier spiral bank configuration significantly increases the number of spiral turns in a compact footprint — improving chrome recovery rates and grade consistency across the full throughput range. The plant operates in a closed-water circuit, minimising environmental impact and on-site water consumption.

Key Outcomes

  • 100+ TPH commercial throughput — operational on schedule
  • Incline conveyor and vibrating screen feed system installed
  • Dual-tier spiral banks for improved recovery and grade
  • Permanent concrete slab foundation with full pump room
  • Closed-water recirculation system operational
  • Tolling operations active post-commissioning
  • All fabrication, coating and delivery in-house

Mining Services Plant Refurbishment Chrome Tailings Mooinooi · North West Zero LTI

Plant De-establishment, Upgrade & Re-erection, Mooinooi NW

Project Overview

This project demonstrates Black Mountain Minerals' full mining services capability: the de-establishment, mechanical refurbishment, spiral upgrade and re-erection of an existing chrome washplant at Mooinooi, North West Province — on a live operational site processing chrome tailings.

The plant was de-established using our 50-tonne mobile crane, transported to our Brits facility for mechanical refurbishment and the installation of tailings-optimised spiral modules specifically selected for the fine-particle, high-slimes characteristics of chrome tailings material. The upgraded plant was then returned to site and re-erected with all commissioning completed without a single lost-time incident.

The client achieved a substantially upgraded processing plant at a fraction of the capital cost of a new build, with improved tailings recovery performance and the confidence of a zero-LTI delivery record on a live, active site.

Key Outcomes

  • Full de-establishment on live site — zero LTI
  • 50-tonne mobile crane deployed for heavy lift
  • Tailings-optimised spiral modules installed
  • Mechanical refurbishment at Brits facility
  • Sandblasting and full recoat completed in-house
  • Re-erection and commissioning on active chrome tailings site
  • Delivered at fraction of new-build cost
