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: Identifying and Analyzing Minerals
Today’s mining industry is faced with a challenge: how to efficiently and cost-effectively extract valuable minerals and raw materials for the industry. Therefore, it is crucial to accurately classify, analyze, and predict the output. Traditional methods can be time-consuming and inaccurate, and output may only be accurately assessed after, for example, costly smelting processes. The mining industry requires advanced imaging technologies with innovative software programs that make it possible to rapidly and reliably classify minerals to increase efficiency and profitability.
The Solution: EVK Hyperspectral Technology to Automate Mineral Classification and Output Predictions in the Process Line
EVK offers machine and plant manufacturers as well as plant operators innovative solutions for the integration of precise mineral analysis and sensor-based sorting decisions in mining.
With the EVK HELIOS hyperspectral camera, the powerful EVK ALPHA data processing platform and the EVK SQALAR data analysis software, objects can be precisely classified based on their chemical composition. Minerals and raw materials can be reliably detected.
Quantitative Chemical Imaging (QCI) makes it possible to analyze materials in real-time directly in the line. Combined 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 thanks to optimized processes and an 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 optical systems partner to efficiently analyze minerals, sensor-based sorting, and control mining yields. We are happy to support your project.
Hyperspectral imaging in the mining industry
Hyperspectral imaging applications are highly diverse and extend to various areas, from reliably detecting contaminants and by-products to purity analysis and quality control or the use of systems for yield predictions, such as extracted copper quantities.
