X-ray fluorescence (XRF) is a non-destructive analytical technique used to determine the chemical composition of materials. How does it work? How accurate is it? Is it safe? Learn more in these resources.
Mine Exploration Information
Quickly identify the most economically viable resources
In all stages of the mining and exploration process, you make decisions based upon your mine model, judgment, and experience. You want to maximize your exploration budgets, pre-screen laboratory samples, identify drill targets quickly, reduce re-mobilization costs, and get an accurate report to the capital markets as fast as possible. Portable x-ray fluorescence (XRF) analyzers and sample collection and preparation tools represent the latest innovations in elemental analysis technology for mining and exploration applications, paving the way to a positive return on investment.
Portable analyzers allow you to take assay analyses in real time, and can be used in mine mapping, ore grade control, and environmental compliance. and the exploration and mining of a wide variety of base metals, precious metals, rare earth elements, mineral fuels, industrial minerals, and gas-bearing strata samples.

There is no instrumental technique to identify rock type directly. Laboratory methods such as x-ray diffraction (XRD) and Raman spectroscopy are used in mineralogy to identify mineral composition of rocks. Now, these techniques are complemented by field-portable x-ray fluorescence (FPXRF) which can not only be used to identify elemental composition, but also the subtle changes in geochemistry of reservoir rocks and monitoring of the gradual transition from one rock type to another.
Although REEs are not as rare as precious metals, their mining and extraction technology is very costly. The exploration and mining of REEs has increased tremendously due to strong demand (commonly used in electronics) and short supply worldwide.
Lab-based techniques such as inductively coupled plasma and atomic absorption spectroscopy (ICP and AAS) are used commonly for analyzing geological samples. These techniques utilize homogeneous rock powder, which eliminates the effects of heterogeneity and uneven distribution of ore minerals in the groundmass or veins/veinlets. However, these methods require completely dissolving the samples in a solution. Since complete dissolution is not achievable for many minerals (including some ore minerals), the assay values are not truly complete.
