According to the ISO 9298 standard [], zinc oxide is classified either as type A, obtained by a direct process (the American process); or type B, obtained by an indirect process (the French process).The direct (American) process …
Abstract. China is the largest producer of lead and zinc concentrate in the world. The lead-zinc mines of China are used to produce multiple products simultaneously. To evaluate the specific environmental impact of the lead-zinc ore mining and beneficiation, life cycle assessment (LCA) was performed by SimaPro 8.5.2 software in this paper.
