Calcined bauxite producer China Mineral Processing (CMP)
started commercial production at its new plant in Guizhou,
South West China, in November.
The newly constructed 80,000-tpy calcination facility, with
rotary kiln and pressurised shaft, produces rotary bauxite lump
between 85-90% Al2O3.
The monthly output is expected to reach 8,000-10,000 tonnes
in the longer-term, according to CMP.
"This is now certain and we have all the permits required,
plus we are unrestricted in production in the fourth quarter
2017 for calcinations of our own mine-produced bauxite," James
Devlin, managing director of CMP Europe sales, told Industrial
CMP’s bauxite mine at Xiuwen, Guizhou,
has proven reserves of
3 million tonnes
CMP’s bauxite mine at Xiuwen, north of Guiyang,
which has estimated reserves of 3 million tonnes, will be
supplying the calcination plant with raw material. The mine has
been in production since June 2012.
In addition, the company also has a contract with the
Aluminum Corp of China (Chalco), which will be able to supply
additional bauxite from its Guizhou operations.
Due to the tough anti-pollution measures being enforced by
the central Chinese government, mining and industrial
activities in provinces around Beijing have been restricted
from October 1.
Production at Guizhou was greatly reduced in October due to
the ban on the use of explosives, but operations should return
to normal between November 2017 and March 2018. This is
because, unlike Shanxi, Guizhou is far from any big city and is
more than 2,000km away from Beijing, so the province is
subjected to less scrutiny.
Bauxite lump produced in Guizhou will be exported from South
China ports, or transported in bulk to CMP’s
crushing plant in Tianjin in late December or January 2018 for
processing into sized refractory material.

Although CMP’s crushing plant in Tianjin has
received environmental permission to work continuously from
November to March 2018, the company told Industrial Minerals
that the facility "has amassed enough raw material stocks of
bauxite and other minerals to be able to continue working
in November, December , and until Chinese New Year in February
2018 (...) but only just."
In November CMP restarted the dryer in Tianjin after five
months closure due to the permission and time taken to retrofit
it to run on gas, the company told Industrial Minerals.
Due to the scarcity of bauxite, demand for the refractory
minerals remains very strong.
To date 3,000 tonnes of bauxite lump and 6,000 tonnes of
crushed material have been sold to different clients for
delivery in December-January 2018.
