Metallurgical Testing

Jul 29, 2013

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.




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)
 Bond Rod & Ball Mill Work Index
 Abrasion Index
 Size Classification & Screening
 Starkey SAG Design Test
 Batch flotation tests
 Locked cycle tests
 Column flotation
 Special gas media flotation
 Reverse & flash flotation
 Agglomeration flotation
 Drum separator
 Belt separator
 High gradient separator


Gravity Concentration


Solid-Liquid Separation

 Shaking tables
 Heavy media cones
 Centrifugal heavy media separation
 Centrifugal concentrators (Falcon and Knelson)
 Mozley Separator
 Standard thickening procedures
 Differential settling
 Vacuum & pressure filtration




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




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
 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




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.




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.




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.
