Metallurgical Testing
Inspectorate’s Metallurgical Division is now a member of the Bureau Veritas world wide organization, including Amdel in Australia. The Vancouver facility offers the Mining Industry a full range of services from bench scale testing to continuous pilot plant operation. We offer a complete metallurgical testing investigative package from the early exploration phase through scoping, pre-feasibility and feasibility to process development for flowsheet design and bankable feasibility.
MINERAL PROCESSING
Our Mineral Processing Laboratories are fully equipped to perform all metallurgical investigations required for ore evaluation and mill design. Testing services include:
| Comminution | Flotation | Magnetic Separation (wet & dry, variable intensity) |

ENVIRONMENTAL
As a continuation of the mineral processing, circuit design and permitting sequence, Inspectorate conducts a number of ore, tailings and waste related environmental tests, including the follows:
ARD static and kinetic testing
Acid-Base accounting
High density sludge evaluation
Cyanide regeneration and/or destruction
Humidity cell tests
HYDROMETALLURGY
We have extensive laboratory facilities to conduct a wide range of hydrometallurgical and bio-hydrometallurgical studies. These include the full scale up from individual batch tests through continuous bench tests to commercial sized pilot plant reactors. The testing capabilities include:
Cyanidation studies (Merrill Crowe, CIP and CIL procedures)
Pressure leaching
Bottle roll and tank leaching
Counter current closed circuit tank leaching
Column leaching up to one meter diameter (4 tonnes)
Diagnostic / sequential leaching
Solvent extraction
Ion exchange
Electrowinning
Differential precipitation
Bio-oxidation of refractory gold ores and concentrates
Biological leaching of base metal ores and concentrates
Biological heap leach simulation
Cyanide and ammonia detoxification
Standard electrowinning technology
Galvanox copper recovery process
BANKABLE FEASIBILITIES
Inspectorate is well recognized in the mining industry for value-added input and quality work. The Metallurgical Division is fully qualified to complete “bankability” testing and mill design. Over the past 19 years, our firm has provided this level of service to most of the major engineering firms working within the mining industry. Our independence, reliability and accountability has been firmly established.
PILOT PLANT
A complete ore treatment pilot plant, can be assembled for any circuit combination, from crushing through to final product with throughput ranging from 1 to 5 tonnes per day, depending on ore hardness.
METALLURGICAL ASSAYING
The Metallurgical Division now has a completely independent assay laboratory dedicated to the specialized analytical and rapid turnaround requirements of the testing laboratory. Analytical services provided include: fire assay, ICP, AA, classical wet assays, XRF, speciation packages, and environmental analysis.
Mineralogical studies are critical to the successful processing of ores. We offer a full range of packages including QEMScan, bulk mineralogical analysis (BMA), particle mineralogical analysis (PMA), modal analysis and conventional optical mineralogy.
