I like how you framed up the image, with the train sinking into the
lower left corner. Quite and industrial scene.

Magnetite (Iron ore - Fe3O4) is a by-product of the Copper flotation
plants
in Phalaborwa. Over half a million tons has been extracted in about 50
years. Only a limited amount is used to make steel, Haematite (Fe2O3)
being
preferred. However, a considerable amount is milled fine to be used in a
slurry for heavy medium separation in the coal industry. A slurry with
an SG
of about 2.5 allows crushed coal to float while the silicate rocks sink.
Most of the Magnetite is recovered magnetically & recycled but
continual top
ups are necessary. The plant in this Pano produces a couple of hundred
tons
of finely milled Magnetite a day. It is transported by rail & by road
to the
coal mines in those reinforced plastic bags you can see at the right.
