Zinc copper natural ore

The overall environmental emissions were due to zinc ore mining and energy consumption in the form of electricity and natural gas. In future, their study would be beneficial to build national LCI database for zinc production in China. LCA of gold–silver–lead–zinc–copper beneficiation (Farjana et al., 2019b)
