Bureau Veritas MineralsMetallurgical Testing Services
MINERALS
Bureau Veritas Minerals (BVM) Metallurgical Division offers the Mining Industry a full range of services from the early exploration phase through scoping, pre-feasibility and feasibility to process development for flowsheet design and bankable feasibility level, including larger-scale continuous pilot plant operation. Our experience includes evaluation of precious metals, base metals and industrial minerals, environmental concerns and production aspects, using both conventional and newly developed technologies.
Mineral ProcessingOur Mineral Processing Laboratories are fully equipped to perform all metallurgical investigations from bench scale to demonstration tests with the focus on developing a practical and economical flow sheet for plant operation whether it is by adapting known technologies to new situations or by developing a new process.
Testing services include:
Continuous Grinding-Gravity-Flotation Pilot PlantA complete ore treatment pilot plant, consisting of crushing – continuous grinding - gravity concentration – rougher/cleaner flotation - tailing thickening, can be assembled for any circuit combination, with throughput ranging from 1 to 5 tonnes per day, depending on ore hardness.
Bankable FeasibilitiesBVM 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 24 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.

HydrometallurgyWe have extensive laboratory facilities to conduct a wide range of hydrometallurgical and bio-hydrometallurgical studies to recover valuable constituents from concentrates or raw minerals using methods based on mass chemistry, where one or more of the mineral structures are changed, in an aqueous environment. Projects have ranged from the recovery of valuable metals from steel furnace dusts, gold and silver extraction from refractory minerals, to heap leaching and solvent extraction of copper. These include the full scale up from individual batch tests through continuous bench tests to commercial sized pilot plant reactors.
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 and 6 meter length(8 tonnes material) ■ Diagnostic / sequential leaching ■ Solvent extraction ■ Ion exchange ■ Electrowinning ■ Differential precipitation ■ Clay beneficiation and processing (roasting, leaching and 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 ■ Galvanox copper recovery process, four-reactor pilot plant with elutriator and thickener
EnvironmentalAs a continuation of the mineral processing, circuit design and permitting sequence, BVM Metallurgical Division conducts a number of ore, tailings and waste related environmental tests, including the follows:
■ ARD static (Acid-Base accounting) and kinetic testing (Humidity Cell and Columns) ■ Shake Flask, SWEP, SPLP, TCLP, MWMP, NAG ■ High density sludge evaluation ■ Cyanide regeneration and/or destruction
Bureau Veritas provide leading testing and inspection services for the global commodities industry
