Our solution effectively separates same-colored waste materials from valuable minerals, solving a major historic problem for several industries.
The paper sector uses talc as filler and coating material, for example, while ceramics specialists need white, high quality talc for catalytic converters and diesel particulate filters. To yield useful pure talc, calcium carbonate – also white – must be removed accurately. Traditionally, talc was sorted manually and with wet methods, such as flotation, at decreasing grain sizes, while color sorting machines have been used to pre-sort recovered material or enrich valuable minerals.
Our sensor-based mineral sorters now make it possible to detect coated material, like the industrial mineral chert, and separate it selectively, at a very high throughput rate. Our innovative, field-proven x-ray transmission technology also delivers significantly higher product yields and quality.
Benefits of sensor-based mineral sorting at a glance
- Contaminant removal: Contaminants can be removed early in the separation process, reducing crushing and classification costs, increasing recovery and enhancing deposit exploitation.
- Product upgrade: Final product can be produced in higher quantities and with its quality improved, which ultimately means increased revenue.
