ies on manganese extraction were mainly focused on the primary resources (Farjana et al. 2019). In most LCA stud-ies carried out on manganese extraction from wastes and low-grade ores, manganese was recovered from a sort of waste which were related to electrolytic manganese metal (EMM). Zhang et al. (2020) conducted an LCA analysis
Figure (PageIndex{2}): Three Common Ores. (left) Iron ore, (middle) Manganese ore – psilomelane, and (right) Lead ore – galena and anglesite. Most metals are found as types of rock in the Earth's crust. These ores contain sufficient minerals with important elements including metals that can be economically extracted from the rock.
