摘要

In 1999, Molymex S.A. de C.V. (Molymex), Mexico (a company wholly owned by Molibdenos y Metales S.A. (Molymet), Chile) decided to install the Haldor Tops0e Wet gas Sulphuric Aicd (WSA) process for cleaning of the 4-5% SO_2 off-gas from their molybdenum sulphide roaster in Cumpas, Mexico to produce sulphuric acid. The decision to install a WSA plant was based on the successful operation of a WSA plant at Molymet's molybdenum sulphide roaster in Santiago, Chile since 1993. This paper describes the process layout of the Cumpas plant, the operating experience of the Santiago plant, and the differences in process design between the two plants. It will furthermore summarise the applications of the WSA process for other roasting plants and smelters within the non-ferrous metals industry producing metals such as copper, lead, and molybdenum.
