Application Development

EVK stands out as one of the few providers in the hyperspectral field, offering other companies an environment where they can develop and successfully market their own application using sensor-based technology.

The Challenge: Identification and Analysis of Minerals

Today's mining industry faces the challenge of efficiently and cost-effectively extracting valuable minerals and raw materials for the industry. Therefore, it is crucial to accurately classify, analyze, and predict yields. Traditional methods can be time-consuming and inaccurate, and yield statements may only be made after, for example, costly smelting processes. The mining industry requires advanced imaging technologies with innovative software programs that enable rapid and reliable classification of minerals to increase efficiency and profitability.

The Solution: Automated Mineral Classification and Yield Prediction with EVK Hyperspectral Technology in the Process Line

EVK offers machine and plant builders, as well as plant operators, innovative solutions for the integration of precise mineral analysis and sensor-based sorting decisions in the mining process.
With the EVK HELIOS hyperspectral camera, the powerful image data processing platform EVK ALPHA, and the data analysis software EVK SQALAR, parts of objects can be classified based on their chemical composition. This enables reliable detection of minerals and raw materials.

Quantitative Chemical Imaging (QCI) allows real-time analysis of materials directly in the line. In combination with proprietary algorithms, key data for optimal process control can be extracted. By selectively sorting out impurities and by-products, it is possible to optimize resource yield and maximize output.

The spatially resolved metal sensor EVK ABAS detects ferrous and non-ferrous metals in real-time. Mining companies can carefully control production yield and increase profitability through optimized processes and efficient resource utilization.

The exact application of hyperspectral imaging in mining depends on specific requirements and technological capabilities. Hyperspectral cameras and sensors are integrated directly into the line, allowing, for example, for continuous purity analysis and quality control. Integrating the technology into the respective process step requires careful planning and adaptation to the individual needs of the mining operation. EVK is your reliable partner for optical systems for efficient mineral analysis, sensor-based sorting, and yield control in mining, and we are happy to support your project.

Use Cases in the Mining Industry

The applications of hyperspectral technology are highly diverse and extend to various areas, from reliable detection of impurities and by-products to purity analysis and quality control or the use of systems for yield predictions, such as for copper quantities earned.

Versatile Applications of Our Sensor-based Systems:
From Purity Analysis and Quality Control to Smart Sorting Commands

EVK products offer a variety of application possibilities that can be used across industries. Quantitative analyses enable continuous monitoring and inspection of the production line. This can successfully ensure the quality and consistency of the sorted and analyzed minerals. The non-contact and non-destructive method also allows the percentage of a mineral to be quantitatively analyzed directly on the line to predict yield.
EVK hyperspectral cameras and sensors are integrated directly into the line and offer diverse application possibilities from sensor-based inspection & monitoring, to quantitative image data analysis, to smart sorting - in real time, of course.
