In mineral processing, the value is in purity. A feed that contains quartz or another high-value mineral mixed with lower-grade material is worth far more once the two are cleanly separated.
MINEXX uses sensor-based detection to identify the target mineral and eject it into a separate stream, raising both the grade of the recovered product and the proportion of it that is captured. For producers of industrial minerals, that improvement in purity and yield is what justifies the investment.
