Despite its growing list of assets, Canyon Coal has
retained the ability to make quick decisions and
execute them rapidly.”
which means the hauling distance will
be reduced over time. There is a ROM tip
area between the two plants from which
both plants are fed. The bigger plant is a
lot more advanced than the small modular
plant, which produces an RB3 product of
zero by 50mm.The new plant will normally
target a 25.5 CV, but that will change to
a 27 CV at certain times, as some coal
seams are of a better quality than others,
which means the products will be blended
to produce a high quality export coal.
Khanye’s new plant is the first of
Canyon Coal’s large coal density media
separator (larcodem) plants built by
contractor Obsideo and operated by
Isimilo DBO, which consists of larcodems
instead of the traditional drum plant, and a
filter press to process the slurry. The coal
mined in the pit is fed into the ROM feed
bin. From there it goes through a primary
crusher, then into a secondary crusher
before it splits off into the larcodem that
produces large and small nuts. After that
the material enters a cyclone that handles
the peas and the duff. Thompson explains
that a secondary stage wash capacity is
planned to be built within the main plant to
wash the discard and produce a middling’s
product. The final products and discard are
stockpiled in an area measuring almost
36 hectares.
Khanye Colliery officially opened in November last year.
Khanye’s Larko Dem plant is complete and will start
operating shortly.
