Industrial Mineral Quarries

Increasing Efficiency, Sustainability and Competitiveness

In the world of volume mining, where limestone quarries churn out a staggering 200,000 tons of material each day, precision is secondary to a sound understanding of quality distribution over large volumes of material.

The need for quality control however, becomes all the more imperative with razor-thin profit margins. Hyperspectral imaging can aid the way we manage the extraction process in volume operations, in this case limestone quarries, and reconcile block model quality and the reality of the material that ends up in the crusher. Traditionally, quality control in mining operations relies on manual sampling and testing, which is labor-intensive, time consuming, and prone to human error.

Hyperspectral imaging offers a proven alternative by providing fast, comprehensive data on the chemical composition and physical properties of mined materials. One of the key advantages of hyperspectral imaging lies in its ability to capture detailed spectral information across hundreds of narrow wavelength bands. This enables mining engineers to analyze small shift in patterns ultimately identifying mineralogy, or substitution of elements and to pick up on quality parameters e.g. indicating changing magnesium or silica content.

Moreover, information derived from hyperspectral imaging can be seamlessly integrated into the existing block model, ensuring that the extraction and transport of material are based on precise geological assumptions.
