:: Construction of Titania Smelter Plant for CYMG in China

Construction of the 85,000 t/yr TiO2 slag smelting plant designed by Bateman Engineering, together with the local Kunming Design Institute, for the Chinese Yunnan Metallurgical Group (CYMG) is well underway.As Bateman Engineering's first major project in China, it will be an important reference for the Group to gain further projects in the region.

With the Kunming Design Institute responsible for most of the detailed engineering of the plant, Bateman Engineering's responsibility includes process design and basic engineering for the entire plant, detailed engineering for the smelter area, design and programming of the plant control system, supervision of erection and commissioning and assistance with procurement of imported equipment.

The plant uses DC arc furnace technology to produce high-grade titania (TiO2) slag from ilmenite mined in the region. Some items of critical equipment related to the DC furnace and slag milling are imported from Europe and South Africa, but the majority of the other equipment is supplied by Chinese suppliers.

Installation of the mechanical equipment starts in July, and commissioning of the plant is planned to commence late in 2008.The plant will produce 85,000 t/yr of high-grade titanium dioxide (TiO2) slag, which is mainly used as a feedstock in the pigment industry. The slag will be produced from a feed of ilmenite utilising DC arc furnace smelting technology in a 30 MW furnace. The furnace will be designed with an offgas scrubber and the cleaned furnace gas will be used as a combustion fuel within the plant, thus maximizing energy efficiency.

CYMG has diverse interests in ferrous and non-ferrous metals. This project is part of the company's plan to move out of lead production and into the TiO2 slag / pigment industry.
