To maximize efficiency, precision and speed of beneficiation, AIHAI was the first talc producer in China installed optical sorting technology in 2012. This near-infrared spectrometry sensor-based solution separates high grade talc from undesired materials, helps to extend the lifespan of mining operations and increases overall value of the talc deposits.
