Most current mineral processing technologies rely on wet processing of the ore, creating an association between mining activities and water consumption. While it is true that wet processing of ore will always consume water, it is possible to significantly reduce water consumption by evaluating water reticulation circuits, available water sources and any dewatering equipment in use.
Metso, PTI, Process Technology and Innovation, believes that the process of reducing water consumption starts with a solid understanding of the current water balance, and PTI can provide assistance with the establishment/ estimation of the current plant water balance. From the water balance, opportunities to improve water utilization are identified. Some typical water saving opportunities with which PTI can assist include:
