Concentrator audit
You receiveSampling campaigns, metallurgical balances, grade-recovery curves, circulating loads, diagnosis of losses by size fraction.
You gainAn action plan ranked by cash-flow impact, using the equipment in place.
Activity 2
Mineral Processing
Improve the grade-recovery performance of your concentrator and convert it into margin and cash.
ForOperating concentrators, plant projects, semi-mechanised operators
Every point of recovery lost goes to tailings, shift after shift. This metal has already been mined, hauled and ground: its cost is committed, and its net smelter value will never be realised.
Our services
What you obtain
Processing flowsheet
You receiveLiberation tests, sized flowsheet, mass and water balances, equipment selection, CAPEX and OPEX per tonne treated.
You gainA flowsheet selected on value, ready for appraisal by your lenders.
Metallurgical support
You receiveCollector, frother and depressant regime, pH, pulp density, daily metallurgical accounting, reagent and energy consumption per tonne, commissioning.
You gainA stable circuit, cost per tonne tracked, deviations corrected the same day.
Concentrate value
You receiveNet smelter return (NSR) model: grade, recovery, penalties, treatment and refining charges, transport, at current Pi Market prices.
You gainThe operating point that maximises margin, not recovery alone.
Why us
- An operating nickel-copper concentrator in Nunavik: pentlandite, chalcopyrite
- The mineral processing group at McGill University
- Every lever quantified in margin and cash with Pi Market
Our resources
How we do it
Flotation, our speciality
Trained in the McGill mineral processing group, a world reference with Professors Finch and Waters. Differential flotation of sulphides (pentlandite, chalcopyrite, pyrrhotite), screening of collectors, frothers and depressants, cell kinetics, pH, pulp density, residence time. Nickel, copper, gold, lithium, graphite, iron, and battery black mass.
Technical data sheetMechanical cells in bank and tank cells
- Collectors, frothers, depressants
- pH, pulp density, residence time
In 3D
Liberating the mineral without overgrinding
Liberation size, ball and rod mills, classification, circulating load: an appropriate particle size liberates the valuable mineral and avoids unnecessary energy expenditure.
Technical data sheetBall mills, vibrating screens
- Liberation size, circulating load
Audit and commission
Concentrator audit, circuit sampling, comparative testing, prioritised recommendations, circuit commissioning, including a magnetite filtration circuit.
Running the plant on measurements
Shift samples, cell flotation in the site laboratory, filtration, screening and daily metallurgical accounting: grade, recovery and tailings are tracked every day.
Technical data sheetLaboratory flotation cell, screens, filters
- Online XRF analyser on the circuit
- Daily metallurgical accounting
Design your plant
Process flow diagram, mass and water balances, equipment selection, capital cost estimate: a project ready for review.
