摘要

A study of refined metallic copper and nickel production was carried out using Life Cycle Assessment methodology to estimate the life cycle emisssions of greenhouse and acid rain gases for these metals using data derived from the literature. Various processing routes were investigated which included a pyrometallurgicaland a hydrometallurgical route for each metal. The effect of anumber of process variables, namely ore grade, fuel type for electricity generation and efficiency of generation were also examined in the study.
