The members of the GMR team have conducted years of testing programs for base and precious metals, as well as industrial minerals. Our work includes flowsheet development, circuit design, regulatory reporting, commissioning and operations troubleshooting.
GMR has a full service analytical laboratory including fires assay, atomic absorption (AA) and inductively coupled plasma mass spectrometry (ICP-MS). Our laboratory process equipment provides extensive applications for crushing, grinding, flotation, gravity and magnetic separation, and classification techniques that are best suited to your project. We have also pioneered novel cost effective gravity recovery of fine gold through our parent company IMG Gold Recovery Inc.
Sulphide and Oxide Flotation – Flotation is a ubiquitous metallurgical practice in today’s mining industry used for the extraction of metals from both sulphide and oxide ores. Though commonplace, successful flotation requires a fine balance of several factors including grind size, reagent quantities, and tank size. GMR is pleased to be on the leading edge of metallurgical laboratories providing the best data to new and established mines and their process plants.
Gravity and Magnetic Separation – Gravity separation is one of the oldest mineral processing techniques, successful gravity separation depends on several variables including particle size and shape and the relative proportions of heavy to light particles in the material to be processed. GMR is well equipped to optimize both gravity and magnetic separation processes with a wide variety of appropriate equipment.
