Sample requirements for HPGR testing procedure
2015-3-15 Eighteen samples of phlogopitite, a rock mainly composed of phlogopite, were prepared for testing in the LABWAL roller press at CETEM. The samples were carefully prepared so that they all have very similar size distributions . The composition of the samples is homogeneous because the original sample is composed by a single mineral, phlogopite mica.
