Four Kinds of Hematite Ore Dressing Processes. Hematite (Fe2O3) is a kind of weak magnetic mineral, and its crystal belongs to the oxide mineral of hexagonal crystal system. The mineral form is dominated by iron oxide. According to its composition, hematite ore can be divided into four varieties, including ilmenite, aluminum hematite, magnesium hematite and hydrohematite.

Concentration of Ores. An ore of a metal is an impure source, this means other than the metal it consists of many other impurities such as sand, grit, clay, rocks etc. These impurities are collectively known as gangue. Gangue is generally commercial valueless and we must separate it from the ore. This entire process is the concentration of ores

OverviewUnit operationsHistoryOther processnferencesSee alsoNotesSources

Mineral processing can involve four general types of unit operation comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes, which is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smalle

Mineral processing can involve four general types of unit operation comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes, which is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smaller the particles processes, the greater the theoretical grade and recovery of the final product, but this is difficult to do with fine particles since they prevent certain concentration processes from occurring.
Comminution is particle size reduction of materials. Comminution may be carried out on either dry materials or slurries. Crushing and grindingare the two primary comminution processes. Crushing is normally carried out on "runofmine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces compression, impact and attrition. Compression and impact forces are extensively used in crushing operations while attrition is the dominant force in grinding. The primarily used equipment in crushing are jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, usually closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant.
