tailings - wikipedia

tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. the extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining, which pulverizes the rock containi

dry magnetic separator for iron ore refining process china

iron ore beneficiation process,iron ore refining process is a iron recover system that concentrate the iron content from various kinds of iron ores, such as magnetite, hematite, limonite, it can also be used to remove the iron content when the iron is regarded as the impurity, it is also presented in the sponge iron production plant, generally speaking a iron ore beneficiation process includes three units, first is crushing, second is grinding and finally is the separation unit.
