Abstract

Lots of resources and energy were consumed from nickel laterite ores mining to nickel products. In addition, large amounts of waste gas, waste water and solid waste were emitted, so it is urgent to explore and utilize laterite nickel ores in more efficient ways. In this article, life cycle assessment method is used to evaluate the three kinds of nickel production processes, energy consumption and waste emissions in these processes were analyzed by using GaBi6 software. The results show that ammonia leaching method is the optimal process based on life cycle assessment. Global warming potential of ammonia leaching method is minimum, 18381(kg), 144.27% lower than that of electric furnace process. Acidification potential of ammonia leaching method is also more minimum comparing with blast furnace process, electric furmace process. Some optimization methods were proposed for these problems, including adjustment of production process and utilization of the wastes comprehensively.
