  • Ore Mineral - an overview | ScienceDirect Topics

    Iron ore minerals, particularly hematite and goethite, are beneficiated by a combination of size fraction, preconcentration, and flotation in stages (Fig. 13.45).Iron ore requires removal of silicate impurities of a finer size by flotation for higher-grade products of +60% Fe. ROM ore at 400–600 mm is fed to a primary crusher with product set at –40 mm.

  • Iron ore - Wikipedia

    Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite, hematite, goethite, limonite or siderite. Ores containing very high quantities of hematite or magnetite are known as "natural ore" or "direct shipping ore", meaning

  • Ore Body - an overview | ScienceDirect Topics

    These ores show the highest and most predictable recovery of all ore types, typically 92–95% gold recovery in laboratory tests, and 85% or greater in field production heaps. Ores must be agglomerated and may require up to 40 kg of cement per metric ton to make stable permeable agglomerates. Many of the West African and Central American heap leaches process this type of ore.

    ORE DEPOSIT TYPES Ore deposits can be classified on the basis of: - • Composition of the deposit (contained elements). • Form of the deposit (size, shape, orientation and ore mineral distribution). • Associated host rocks or geological structures (ore associations). • Interpreted genesis of the deposit (processes, controls). Geologists generally prefer genetic classification schemes
