在水是稀缺商品的采矿环境中，矿物的干法加工越来越有吸引力。基于传感器的分选有可能在处理的早期阶段从脉石中进行矿石的干燥分离，也有助于减少由于下游破碎而造成的能源消耗。为了开发基于传感器的分选过程，选择合适的传感器是至关重要的。在实践中，近红外传感器可以测量矿物和岩石中含有的碳酸盐、羟基和水基的特征。本文研究了建立近红外传感器识别热液形成矿物的适用性的过程。结论是，近红外光谱中的特征吸收特征比吸收水平提供了更可靠的分离矿物的途径。
Dry processing of minerals is increasingly attractive in a mining environment where water is a scarce commodity. Sensor-based sorting has the potential to perform dry separation of ore from gangue at an early stage of the processing, also helping to reduce energy consumption due to downstream crushing. In order to develop a sensor-based sorting process, selection of a suitable sensor is of critical importance. In practice, a near infrared sensor can measure characteristic features of carbonate, hydroxyl and water groups contained in minerals and rocks. This paper examines the process of establishing the suitability of a near infrared sensor for distinguishing hydrothermally-formed minerals. It is concluded that characteristic absorption features in near infrared spectra offer a more robust route to separating out minerals than the level of absorption.
