2 million long tons of annual pellet production capacity and 55 million long tons of proven and probable crude ore
Prior to the completion of this, ore from the 50,000 t crude ore
bin (-200 mm) passed through the fine crushing plant (two primary and three secondary cone crushers) before reporting to the 45,000 t fine ore bin (-16 mm).
However total manganese mining and production is led by China which turns out about 35% of crude ore
Jacobs Engineering Group, together with MCA Group, recently received industry recognition of its achievements on a project to extend the life of a large crude ore
bin for Glencore's Mount Isa mines in Queensland, Australia.

Despite a steep decline in the world economy at the close of 2008, production of crude ore
in both of LKAB's iron ore mines was record-breaking.
However, the low-grade ores required about three times as much crude ore
to be mined for each ton of concentrate that could be shipped.
The largest is the Masua mine which extracted more than 400,000 t of crude ore
followed by the Monteponi group's mines with around 200,000 t.
The facility began operation in 1962 and has produced more than one billion tonnes of crude ore
with an average iron content of 39 percent.
To get the unit consumption figures, the total net consumption described above has been divided by the production 1992 of crude ore
, concentrate, and recoverable metal content respectively, as given by the Bureau of the Census or the U.
production from the two lead-zinc ore mines Grund (Preussag AG Metall) and Meggen (Sachtleben Bergbau GmbH) declined by 8% in 1990 to under 900,000 t.
These price increases are necessary to offset rising costs associated with mining, processing, packaging, and purchased crude ore
