kidney ore hematite Hematite is one of the most abundant minerals on Earth's surface and in the shallow crust. It is an iron oxide with a chemical composition of Fe2O3. It is a common rockforming mineral found in sedimentary, metamorphic, and igneous rocks at locations throughout the world. Hematite is the most important ore of iron.
CHAPTER 11 APPLICATIONS OF ORE MICROSCOPY IN MINERAL TECHNOLOGY INTRODUCTION The extraction ofspecific valuable minerals from their naturally occurring ores is variously termed "ore dressing," "mineral dressing," and "mineral beneficiation." For most metalliferous ores produced by mining operations,
Iron ore is primarily mined and refined through a process called smelting. Smelting is a heating process in which the Iron ore is heated along with coke (charcoal) and limestone in a blast furnace. The heating process melts the iron contained in the mixture and eliminates much of the carbon that is contained.
