Near-Infrared Spectroscopy (NIR)

Critical components of any ore processing automation strategy are the sensors that provide compositional, mineralogical, and ore property information that are essential for process optimization decisions. On-line over-the-conveyor sensors provide real-time information that is then available for feed-forward control of a…READ MORE >

In the following case study, we discuss the added value of XRD for the mineralogical analysis of lateritic iron ore.

In the blog about “The value of mineralogical monitoring” we discussed the importance of mineralogical monitoring for efficient ore beneficiation on the examples of copper and nickel ores. This blog elaborates on the nickel ore application in more detail. Nickel…READ MORE >

Most people using satellite or aerial imagery understand the importance of geometric calibration; you need to tie the pixels in the imagery to the corresponding coordinate locations on the earth so that you can use the imagery in mapping applications,…READ MORE >

We are often asked questions like, “how do I measure my product using ASD near-infrared (NIR)?” Of course, my standard answer is, “it depends.” Since so much depends on the assumptions and conditions, I thought it would be useful to…READ MORE >

Partial least squares regression (PLSR) is a powerful tool that makes use of the information at all wavelengths and provides the means for the quantitative determination of a wide variety of plant canopy properties. Past studies that limited their analysis…READ MORE >

Remote Cosine Receptors (RCR) are utilized for full hemispherical absolute energy measurements. This allows the spectroradiometer to directly measure the total full hemispherical irradiance being emitted by the sun or an artificial light source as well as the corresponding full…READ MORE >

Accurate chemical analysis has long been integral to mining, from early exploration to mine development, ore sorting, extraction, and waste management.
