| 英文摘要 | The traditional sodium roasting process has a number of disadvantages including low vanadium and chromium extraction rate, generation of waste water and toxic residue. Recently, a new vanadium production process based on the sub-molten salt (SMS) technology was developed by IPE, CAS and HBIS Group Co., Ltd. And a 50 kt demonstration plant was built in 2017. After two years operation, many reliable industrial data were obtained. In this paper, the cleaner production level of new technology was analyzed by selecting six first-class indexes, i.e. resource and energy utilization, production technology, pollutant discharge, comprehensive utilization of resources, product characteristics, environmental management and 27 second-class indexes under them. The analysis results show that the cleaner production level of new process is 98.02, which means that this technology belongs to high level of cleaner production. The new technology could realize efficient extraction of both vanadium and chromium under mild reaction condition, providing technical supports for the effective utilization of the 3.6 billion tons of high-chromium containing vanadium titano-magnetite ores in China and can be the green production leader of vanadium chemical industry. 漏 2021, Science Press.
