Ores often contain more than one valuable mineral or metal; thus, the joint production of metal concentrates or refined metals is often unavoidable. Nuss and Eckelman highlighted the interconnectedness of metals and mineral production: 42 out of the 63 investigated metals are obtained as co-products in multioutput processes. Co …
