Why iron ore grade is now more important than ever Stockhead
Special Report: Declining iron ore grades globally and the rising demand from steelmakers for higher grade product is creating the perfect storm for explorers with the goods. In Australia, hematite has been the dominant iron ore mined since the early 1960s, accounting for about 96 per cent of the country’s iron ore exports. And since []The low-grade iron ore sample obtained from Wadi Halfa iron ore Ali, M.N.W., et al., 2004.

Ore, Composition and Classification of SpringerLink
Primary diamond ores grades are expressed in ca/t or mg/t (1 carat =0.2 g). The placer grade is expressed in g/m 3 or kg/m 3. In mineral exploration, the commonly used boundary grade refers to the lowest grade dividing the boundary between ores and non-ores. Industrial grade refers to the lowest average grade of the ore section or ore This has led to Sudan’s mining officials rating the country as Africa’s “Next Major Gold Mining Destination”. While most the country’s mineral reserves remain underdeveloped, mining in Sudan contributes about 90t of gold to the global market per annum, making it the 10th largest gold producer in the world. Most of this is mined in theSudan Aiming to be Africa’s ‘Next Major Gold Mining Destination’

Mining in Sudan Pan African Resources: Home
Despite riches of gold, iron ore, chromite, zinc, aluminium, nickel, and many other minerals, mining in Sudan contributes just 4% to the country’s GDP, with the yellow metal being the main driver. Now the industry may be in for a further boost as Pan African Resources has secured five prospecting concessions in a +/- 1 100 km2 area in They are classified according to the percentage of metallic iron in them: Magnetite: It is the most valuable type of iron ore. It is made up of more than 70% metallic iron. It is black and has magnetic properties. Hematite: It is composed of 65-70 per cent metallic iron. It’s a combination of red and brown.Iron Ore, Types, Uses, Distribution in India & World Map
