Physical separation

Introduction

MINTEK has many years’ experience in developing techniques for the physical separation of metallic and non-metallic minerals. South Africa’s andalusite industry was founded on work done at Mintek. More recently, dense-media separation has been incorporated into platinum-group metals flowsheets, to separate barren waste rock from ore prior to milling. The beneficiation of chromite and iron ore using gravity and magnetic separation and vermiculite upgrading by dry separation techniques, have become important activities.
