Chromite ore was extracted from open-pit mines reaching depths of approximately 200 meters until 2005 In 2003 underground mining began The underground mine is accessible either via an incline ramp or a mine shaft Ore extraction started at level 500 from which the process proceeds upwards towards the bottom of the open-pit
Another major groups of deposits in the mafic layered complexes are platinum group elements and chrome deposits but unlike copper nickel massive sulfides they don t form as puddles on the floor of the intrusions they form in discrete layers well up in the magma chamber The PGE s that s platinum palladium rhodium with less amounts of osmium ruthenium and iridium are often but not
May 16 2012· Podiform chromite deposits tend to be very self-contained like raisins there is very little external indication or halo that you are even close to the chromite body in most cases In my experimentation in the Josephine Ultramafic Complex a microgravity profile could readily detect pods we already knew existed and even suggested several others
