Harsco Metals & Minerals

CAMP HILL, PA (November 11, 2011) . . . In the largest and most impressive ceremony in Company history, the groundbreaking for Harsco Corporation’s (NYSE: HSC) new joint venture slag utilization project with leading Chinese steelmaker TISCO was celebrated this week in Shanxi Province, China. The ceremony, attended by more than 1,000 guests and covered extensively by Chinese media, featured presentations from senior Chinese government officials and U.S. Ambassador to China Gary Locke.

Under its previously-announced 25-year environmental solutions contract, Harsco will apply its proprietary separation technologies to extract high-value metallic content from TISCO’s steelmaking slag for production re-use. In parallel, Harsco will also develop commercial market opportunities throughout China for utilizing slag co-products to revitalize potentially thousands of acres of prime agricultural croplands and contribute to a broad range of industrial applications.

In his remarks, Ambassador Locke praised Harsco and TISCO for working together to address business interests in combination with a healthier and more sustainable environment. “This type of cooperation between companies from the U.S. and China is proof that environmental stewardship is a job-creating enterprise, one that will reap benefits in both of our countries.” Shanxi Province Governor Wang, Jun added that the project is the province’s largest involving an American company with a focus on building a “green Shanxi.”

Harsco anticipates that the metal recovery operations will begin in late 2012, and market development for the agricultural fertilizer and other commercial by-products will proceed in parallel, with an estimated start date of 2014. When fully operational, the project is expected to utilize 100 percent of the steel slag generated by TISCO and have zero discharge, thereby eliminating the need for the material’s industrial landfill.

“It has always been the goal of TISCO to develop itself into a truly green and model steel mill,” remarked TISCO Chairman Li Xiaobo. “The close cooperation between TISCO and Harsco is a most important step towards this goal. Harsco’s advanced technology and expertise gives much needed and valuable support to the success of the project.”
