9 Ore Deposits and Economic Minerals – Mineralogy

Gold occurs in many different ore deposits. The world''s largest, the Witwatersrand deposit of northeastern South Africa, dominates world production. 40% of all the gold ever mined came from Witwatersrand ores. Figure 9.30 shows an example of very high-grade ore from the Blyvooruitzicht Gold Mine of that region.NATURAL RESOURCES SUSTAINABILITY: IRON ORE MININGWhen the iron grade is too low to transport the ore, the ore must be agglomerated which demands a considerable amount of energy (1,500 MJ/ton of ore during pelletisation [8]). Because the energy demand depends on the iron grade, a magnetite with an iron content of 72 % can be compared to a hematite with an iron content of 62 %.
