Mixed copper ore
Compare sulfide and oxide response, sulfidization where applicable, pH, reagents, kinetics, regrind, grade and recovery.
Metallurgical testwork
A useful test begins with a representative sample and ends with a decision.
We use testwork to answer decisions—not simply to generate laboratory reports. Every test should have a purpose: confirm an assumption, compare a route, identify a loss, define a product or reduce uncertainty before scale-up.
Sequence
Design the program from the decision question.
We design each stage around the decision question, preserve sample identity and expect the results to reconcile.
01
Define the sample
Source, lot or domain, mass, particle size, moisture, collection protocol and representativeness.
02
Characterize
Head assay, mineralogy, liberation, associations, sequential Cu or Au deportment where appropriate.
03
Bench test
Gravity, flotation, leach or other test with defined variables and objectives.
04
Analyze products
Feed, concentrates, intermediates and tailings with mass, assay and moisture as applicable.
05
Close balances
Reconcile mass and metal, compare repeatability and review anomalous results.
06
Translate to decision
Define next test, flowsheet, operating condition, commercial constraint or rejection criterion.
Testwork design
Priorities by material type.
We adapt the program to the mineralogy and the final product rather than force every material through the same test sequence.
Gold ore
Separate gravity response, sulfide flotation, residual deportment and eventual leach response.
Product quality
Assay impurities and moisture early to avoid optimizing a concentrate that later has poor marketability.
Technical chain
Trace samples and results.
We expect every metallurgical result to trace back to the original sample and the lot or domain it represents.
