nov 06, 2020 01 1.the pre-beneficiation of weak magnetic iron ore. weak magnetic ores are mainly hematite, false hematite, mirrorite, limonite and so on. to gain better iron minerals, the common pre-beneficiations of iron ore are strong magnetic separation and gravity separation.,beneficiation of iron ores ispatguru,apr 03, 2014 dso, gravity separation, iron ore, iron ore beneficiation, magnetic separation, beneficiation of iron ores. iron ore is a mineral which is used after extraction and processing for the production of iron and steel. the main ores of iron usually contain fe2o3 70 iron, hematite or fe3o4 72 iron. magnetite.
iron ore is beneficiated using separation steps based on mineral composition without the use of separation steps based entirely on size. in a preferred sequence of steps the iron ore is passed from a ball mill through a magnetic separator where low iron content tailings are rejected and the concentrate passed to a flotation step, where a high iron content concentrate froth is made and the,ore beneficiation an overview sciencedirect topics,the principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite andor magnetite, and silica, principally in the form of quartz. the use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.
