  • 4. Control of the world mineral industry

    The state concerns of Chile, Zaire and Zambia had equal relative shares in smelting and in ore extraction, but the share of the eight UK and US 'majors' was higher for smelting than for ore production, since they controlled 35% of the smelting capacity of the non-socialist world as against 24% for the big state firms of Chile, Zaire and Zambia.

    Feb 06, 2020 Exploration of the area has shown findings of 25-45% iron in the ore and an estimation is that the deposit contains at least 600 million tonnes of iron that could be extracted over 60 years. For every 10 million tonnes of iron (which is an annual estimate for the first 15 years), 150 million tonnes of aggregate would be extracted.

    produced depends on the type of mineral extracted, as well as the size of the mine. Gold and silver are among the most wasteful metals, with more than 99 percent of ore extracted ending up as waste. By contrast, iron mining is less wasteful, with approximately 60 percent of the ore extracted processed as waste (Da Rosa, 1997; Sampat, 2003).
