To carry out the mandates you entrust to us
Well-prepared to carry out tasks from simple screenings to comprehensive pilot projects on a semi-industrial scale of a complete ore processing circuit
Corem has a wide range of equipment to carry out pilot testing of comminution circuits. Most of it is modular and mobile; this allows flexible circuit configurations to meet clients objectives.
The comminution group has also developed expertise in the simulation of different types of mills and comminution circuits and owns recognized simulation software for grinding circuits (such as JKSimMet) in addition to in-house simulators.

Corem has a wide range of gravimetric, magnetic and electrostatic separation equipment to conduct almost any task at the bench and pilot scales.In addition to standard equipment, such as spirals or hindered settlers, Corem possesses the last generation of gravity separators.
With those equipment and its expertise, Corem can push gravity separation up a notch and separate finer ore or minerals with low density differences or that are normally out of the range of traditional separation technologies.
Instrumented flotation columns 25 ft x 2, 4, 6 in. and 16 ft x 12 in.)
On stream analysis using LIBS technology
Portable flotation columns
The flotation laboratory is equipped with cells of various sizes, all equipped with monitoring instruments for an accurate control of each flotation test.
Metallurgical performances can be validated through lock cycle or semi-industrial continuous tests.
An applied mineralogy laboratory
An ISO / IEC 17025:2005 accredited chemical analysis laboratory
Corem is capable of addressing a very wide span of flotation issues, from developing flotation strategies based on ore-specific properties to explaining performance mishaps in existing plants.
Corem maintains a complete hydrometallurgical sector for handling, at the laboratory and semi-industrial scales, all mineral acids and bases under high temperature or high pressure.
Whether in order to concentrate the metals of interest or to remove metal impurities in a non-metallic deposit such as graphite, the expertise of its team is well established and capable of providing substantial added value to every project Corem is entrusted with.
Pressure filter and vacuum filter (horizontal and vertical)
From the results of mineralogical analyses carried out in COREM’s laboratories, a multidisciplinary team works together to develop all stages of a project and define an experimental flowsheet.
Corem uses state-of-the-art equipment and follows standardised procedures to guarantee the preparation of representative samples out of bulk samples from the laboratory, the pilot plant or from the deposit.
Samples of any origin (crushing, grinding, sieving, shaking table separation, dense media separation, magnetic separation, etc.) can be studied in bulk or mounted into high quality polished or thin layer sections in COREM’s mineralogical laboratory.
The MLA is used to conduct quantitative mineralogical studies on various ores and process samples.

Iron ore pellets characterization
Pelletizing and thermal processes
Corem offers high and proven expertise in optimizing the chemical composition of various types of iron ore pellets and their firing cycle. Pot-grate or grate-kiln-cooler test rigs are used to optimize firing conditions for either the travelling grate or the grate-kiln processes. Pelletizing test work can be carried out at the:
Laboratory scale, using a balling tire or disk in combination with basket firing, with the capacity to fire up to six different samples in one test;
Pilot scale, using a 1 m pelletizing disk in combination with pot-grate or grate-kiln-cooler firing tests.
Corem can also determine pellet properties following their reduction at high temperature
Corem has all the equipment and necessary expertise to perform tests meeting the highest quality standards (ISO international standards, and other standards). Corem is an active member of the ISO/TC/102 committee for the development of ISO standards for iron ore and direct reduced iron ore. Corem chairs the CAC ISO/TC/102/SC3 Canadian sub-committee on physical testing. Corem’s pyrometallurgical characterization laboratory is certified ISO 9001:2015.
