Engineering a More Circular Future for Mineral Processing
We integrate mineral process engineering, plant optimization and technical procurement with circularity, innovation and optimization — maximising resource potential while decoupling production from environmental impact.
“More value from every tonne of ore, every drop of water, and every unit of energy.”

Circularity in mineral processing does not begin at end-of-life recycling. It begins inside the flowsheet.
From Conventional Plants to Circular Plants
“We engineer solutions that make mineral processing more productive, more resource-efficient and more circular.”

Three positions on where circularity actually starts in a concentrator — the resource case, the water case and the tailings case. Each is summarised in the sections that follow and published in full.
From Resource Consumption to Resource Circularity
Why the transition is becoming essential, and where circularity starts.
Water Circularity in Mineral Processing
Why the future of mineral processing depends on water efficiency.

Our Projects
Four plants, built and running, that turn low-grade ore, mine waste and plant tailings into saleable iron concentrate.
From Conventional Processing to Improved Performance
Three ways a concentrator reaches us: it needs a product it cannot currently make, it needs more out of the circuit it already runs, or it does not exist yet. The engineering is the same discipline in all three — the constraints are what differ.
“Our role does not end when the equipment is specified. It ends when the solution delivers measurable value.”
Decisions Made Before Equipment Is Specified
Most of the value in a concentrator is fixed by choices made long before procurement opens. Consulting is where we test those choices against the ore, the water, the power and the economics that will actually apply.
An independent opinion is only useful if it can say no to the option that pays us more.
More From the Plant You Already Own
Ore grades decline, water gets scarcer and the circuit was designed for the deposit as it was understood a decade ago. Optimization closes that gap inside the existing asset, without waiting for a new plant.
Every improvement is stated as a number the plant can verify: recovery, tonnes, m³ per tonne, kWh per tonne.
Procurement Led by the Engineers Who Specified the Duty
Equipment is bought against a process duty, not a catalogue line. The same people who assess the flowsheet write the specification, read the bids and hold the vendor to the schedule — so a procurement decision stays a technical decision from enquiry to readiness for shipment.
Our scope culminates at readiness for shipment. International freight, shipping and customs sit outside it — stated plainly, because knowing where a scope ends is part of delivering it.
From Enquiry to Purchase Order
Every award is traceable: what was asked for, what was offered, what was accepted and why.
Expediting Is Where Schedules Are Held
The window between purchase order and readiness for shipment is where most equipment schedules quietly slip. We hold that window: sitting between client and vendor, reading manufacturing progress against the promised dates, and raising a recovery plan while it is still a recovery plan.
Two delivery arms, one scope boundary — and no ambiguity about where either ends.
Three Disciplines, One Flowsheet
Thirty years from magnet to flowsheet.
We began by designing and manufacturing magnetic systems and equipment, building our expertise from the ground up, and evolved into a technology-driven engineering company. Today our engineering solutions and installed facilities produce over 20 million tonnes of iron ore concentrate annually across global markets — applied to greenfield developments and existing brownfield operations alike.
A Global Network of Specialists
Our strength lies in the expertise of our people. A global network of highly skilled engineers and renowned mineral processing specialists lets us assemble the right expertise for each project, rather than fitting every project to one fixed team.
What We Aim to Achieve
“More value from every tonne of ore, every drop of water and every unit of energy.”
