ODM HMC preparation (SG 3.3)



Overburden Drilling Management, preparation of heavy mineral concentrates, using undiluted methylene iodide (SG 3.3)

General Methodology:

Sample weight is reported as total moist mass.  The proportion of the sample coarser than 10 mesh (2 mm) is reported as percent gravel.  Moisture content was determined by air dry weight loss of the split used to prepare the <63 micron fraction.  The total moist weight was adjusted on the basis of gravel and moisture content to produce a weight for dry <2 mm or -10 mesh material.  The weight of -10 mesh, >3.3 specific gravity, ferromagnetic minerals (FM), almost entirely magnetite, as well as the -10 mesh nonferromagnetic heavy mineral concentrate (NFM), are reported as grams per 10 kg of dry -10 mesh.
