  • Ore - Wikipedia

    Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit.Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains.Jan 01, 2015  Hematite and magnetite are the most prominent iron ores. Most of the high-grade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− 31.5 + 6.3 mm) and fines (approximately − 6.3 mm) products.Developments in iron ore comminution and classification ...There are two main types of iron ores – hematite and magnetite. Hematite is higher grade in the ground, while magnetite deposits are large and quite low grade – but produce very high-grade products.Why iron ore grade is now more important than ever

  • AI-based scanner to identify ore grades - Australian Mining

    Mar 05, 2021  The current practice of ore-grade classification does not allow for the use of precise ore grade maps in mine planning, which reduces productivity and efficiency gains. The AI scanner uses visible and infrared light to classify minerals in the mine face and real-time mapping to allow the mining process to be planned before digging starts.IRON ORE . 2020 was $84.73 per ton in April compared with the low of $76.16 per ton in January 2019.
