One Green Field Megaton Grade Large Alumina Refinery with Successful Engineering & Operation Experience

摘要

The Phase I alumina project (1.6million tons/arnmetallurgical grade alumina) of the Guangxi Huayin AluminumrnCorporation Limited is a greenfield construction project withrnto-date, the largest disposable investment in the Chinesernalumina industry. The project is based on a diasporic bauxiternwhich is difficult to grind and dissolve, with a high aluminum &rnlow silicon content. Two years of operational experience showsrnthat the comprehensive energy consumption per ton aluminarnproduction is only 10.51GJ/t. This article introduces the processrnscheme & technical measures adopted in the engineering andrnoperational stages of this project.
