Separability tests
You receiveGravity, magnetic and flotation separation on your material, with a complete metallurgical balance.
You gainYour ore's response, measured before any purchase.
Activity 4
Laboratory Testing
Validate the process flowsheet at small scale before any capital commitment.
ForPlant projects, operators, recyclers
Equipment selected from a catalogue may never reach its nameplate performance. A process error is paid for throughout the life of the plant.

Our resources
How we do it
Falcon concentrator
Gravity separation under high centrifugal acceleration, for fine particles that tables cannot capture. We optimise acceleration, feed rate and percent solids.
Technical data sheetSepro Falcon L40 UltraFine (UF), smooth polyurethane bowl
- ≈ 300 G (≈ 80 Hz), −38 µm feed
- Pulp at 5% solids, 2 L/min, peristaltic pump
- Agitation at 400 rpm, ≈ 300 g per pass, 5 passes
In 3D
WHIMS magnetic separation
The high-intensity separator extracts weakly magnetic particles, up to 1.5 T.
Technical data sheetLaboratory WHIMS separator, grooved stainless steel matrix
- Field 0.5 then 1.0 then 1.5 T
- Pulp at 5% solids, 2 L/min
- LFP captured at low field, NMC at higher field, graphite non-magnetic

Shaking table
Density separation on a water film: a direct and demonstrative test for dense minerals.
Flotation in a laboratory cell
Our method comes from the McGill mineral processing group, a world reference in flotation with Professors Finch and Waters. Reagents dosed, pulp conditioned, froth scraped, concentrate and tailings weighed then assayed. We compare collectors, frothers and depressants on your material, and you know what recovery to expect in the plant. Our practice comes from the laboratory of the Canadian Royalties nickel-copper concentrator.
Technical data sheetLaboratory flotation cell
- Collectors, frothers, depressants dosed
- pH, pulp density, conditioning and froth skimming times
- Concentrate and waste weighed, assayed, mass balance
In 3D
Sonication
Ultrasound cleans the surfaces and disperses aggregates before separation.
Grinding and screening
Ball and rod mills, wet grinding, sieves: the right grind size, measured before it is fixed.
Technical data sheetPorcelain jar mill, Ro-Tap sieve shaker, Gilson sieves
- 350 rpm, 15 × 2 min, ceramic balls Ø 10 to 20 mm
- Cuts at 150 µm and 38 µm
Sampling without bias
Splitters, weighings, test plans with replicates: a result that repeats is a reliable result.
Solid-liquid separation
Sedimentation, centrifugation, filtration, drying: to recover each product cleanly and close the balance.
Technical data sheetVacuum and pressure filtration
- Whatman grade 202 paper
- Drying at 60 °C for 12 h
Measured products
Each fraction is weighed, analysed and compared: you see where each metal goes.
In the laboratory
Day-to-day work at McGill University.
From laboratory to flowsheet
Each test has its place in the flowsheet: from reception to black mass, then graphite separation and purification. Click on a unit and its streams light up from feed to product.
