Porduction begins at 80,000 tonne calcination facility in Guizhou

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 Minerals.

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.
