Fluctuating commodity prices and declining ore grades in today’s volatile economic landscape demand that the mining industry find innovative and sophisticated ways to optimize mine production and reduce costs. Traditional mineral testing methods are necessary, but also time-consuming and costly, leaving a mining operation vulnerable to potentially high risks of out-of-spec product and waste from over or under processing while waiting for laboratory results.
The ability to accurately determine geometallurgical properties of ore prior to chemical treatment is vital to mine optimization. Real-time feedback of ‘problem’ mineral concentration levels can help operators at heap leach and floatation operations immediately address processes to improve ore recovery and, in some cases, mine safety by optimizing acid usage. Additionally, mineralogical information can help geotech crews in predicting slope stability, assist mine planners in mining sequencing and determination of pit wall angles, and can be a crucial piece of ore control and communition models.
Near-infrared (NIR) technology is an environmentally friendly analytical method which has been used for decades for testing and modeling of natural resources. The NIR technique uses light reflectance, an established, safe, real-time technology to identify minerals, particularly clays. ASD’s measurement solutions provide state-of-the-art NIR technology ideally suited for mineral processing with real-time analysis of ore feeds, drill/blast chips, geologic core and metallurgical pulps, all requiring little or no sample preparation. ASD’s systems provide multiple configurations ideal for mining production, including field-portable, benchtop, and online options, allowing for streamlined analyses at any number of sites and facilities. ASD’s mineral analysis equipment can quickly determine a wide variety of metallurgical and mineralogical variables, including:
- Detailed clay mineralogy, eg. Kaolinite, dickite, smectite and montmorillonite
- Total swelling clays
- Iron (and other transition elements) oxides and hydroxides
- Acid consumption
- Some physical parameters if correlative to deposit mineralogy
NIR spectroscopy is a consistent, cost-effective technology that has been used for decades in the analysis of worldwide natural resources. As a rapid and reliable mineral exploration technique, it has proven to be an ideal mineral identification tool for geologists and earth researchers. ASD analyzers offer several key advantages for mineral processing over the modern production line:
- Real-time sample analysis
- Non-contact, non-destructive analysis
- Real-time feedback that moves at the pace of the production line
- Continuous feedforward or feedback data
- Easy integration with any site’s information and control systems
- Energy efficient and environmentally friendly
