Other challenges have to be overcome if the valuable minerals are tungsten bearing minerals (i.e. scheelite or wolframite) due to their brittleness which requires to carefully design the beneficiation flowsheet in order to avoid overgrinding and loss of tungsten in the fine particles.

This paper aims to compare a beneficiation flowsheet including an EPF treatment in the comminution circuit to a conventional pathway where the EPF step was replaced by a series of jaw crushers. Tests were performed on a skarn ore containing scheelite as the main mineral of interest. This ore is characterized by a finegrained mineralogy and represents a challenge to conventional comminution processing, requiring fine grinding to liberate the valuable minerals. Fine grinding has high energy requirements and Kathy Bru Formal analysis Investigation Methodology Conceptualization a,⁎
