Talc, Gypsum, Limestone, Dolomite and Kaolinite are some of the more common industrial minerals that can be analyzed with near infrared (NIR) spectroscopy, which uses light reflectance to safely identify minerals. Many accessory minerals like illite and smectite clays, serpentines and magnesite are also quickly identified with NIR. Industrial mineral miners use NIR for more accurate deposit modelling, field identification (ore vs waste; ore grades), quality assurance/quality control and sorting decisions.
NIR spectroscopy is a consistent, cost-effective technology that has been used for decades in the analysis of worldwide natural resources. As a rapid and reliable mineral exploration technique, it has proven to be an ideal mineral identification tool for geologists and earth researchers. When compared to other mineral techniques, NIR spectroscopy can:
- Provide real-time results for real-time decision making
- Easy technician-level operation with no safety concerns
- Cost effectively analyze hundreds of samples in a day
- Flexible, mobile setup: in the field, core shack, adjacent to drill rig, field camp, laboratory, office
- Provide In situ field measurements
- Handle a variety of sample types with little or no sample preparation required
ASD developed the TerraSpec Halo and the TerraSpec 4 as user-friendly, rapid, field-portable systems for characterizing hundreds of mineralogical samples per day. TerraSpec instruments adapt easily to different environments—the laboratory, the field, or a drilling site—providing the real-time information necessary to optimize mining exploration processes. The system can be used to develop a wide range of models for analyzing many sample types, including outcrops, hand specimens, core and drill chips—all with little or no sample preparation.
