Metso said it will supply filtration equipment to Taigang Group Lanxian Mining Co. Ltd. (TISCO), the largest stainless steel manufacturer in China, with delivery scheduled for the first quarter of 2012. The value of the contract was not disclosed.

The order comprises seven units of vertical plate pressure filters, wear and spare parts, as well as services related to installation, start-up, commissioning and technical supervision. The pressure filters, Metso’s model VPA2050, are medium pressure-type units operating in the range of 6-10 bar. These filters are based on the “air through-blow” dewatering concept, whereby water is displaced by air as it passes through a filter cake. Typically, they are used to filter metallic minerals, industrial minerals, coal and tailings.

The equipment is for concentrate filtering for TISCO’s Yuanjiacun iron ore processing plant in Lan county, Shanxi province. The plant is expected to start operation in May 2012 with a daily processing capacity of 22,000–23,000 tons of iron ore concentrate.

The Yuanjiacun plant is designed to process 22 million tons of raw iron ore per year. When completed, Yuanjiacun will be the largest iron ore processing plant in China. TISCO is among the world’s largest producers of stainless steel. In 2010, the company’s net sales were €11.7 billion.
