Manganese sits within Metals & Mining, the physical foundation under construction, electronics, and the energy transition alike, a category with a real, though adjacent, scale: $500B+ in new mining investment needed by 2040, rising to $1.7T across mining, processing, and infrastructure by 2050 — an investment-need figure, not total market size (World Bank). Manganese is sourced like all 20 of the category's items — USGS's Mineral Commodity Summaries and World Steel Association production data back the full ranked list, with no editorial-judgment items in this category.
