In comparison magnetite ore has lower iron content when mined of between 25% and 40% Fe and requires processing, or magnetic separation, to separate magnetic minerals from other minerals in the ore. The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe3O4) which when processed produces a magnetite concentrate with a magnetic content in excess of 96% magnetics

Magnetite Processing. Magnetite is mostly granular aggregates with strong magnetism and wide distribution. According to the different types of iron-bearing minerals, magnetite can be divided into single magnetite and mixed ore. In general, single magnet ore is often selected by weak magnetic separation method, and multi-metal magnet ore and mixed ore are usually combined process of multiple …

This type of magnetic separation machine is used in wet separation processes for smaller than 1,2 mm ( – 200 mesh of 30-100 %) of fine grained red mine (hematite) limonite, manganese ore, ilmenite and some kinds of weakly magnetic minerals like quartz, feldspar, nepheline ore and kaolin in order to remove impurity iron and to purify them

hydrogen reduction of hematite ore fines to magnetite ore

hydrogen reduction of hematite ore fines to magnetite ore

This paper, as a preliminary study of the innovative process, mainly describes the process of low-temperature hydrogen reduction of hematite ore and magnetic separation of the resulting magnetite ore, since hydrogen, which is the main component of COG, is an efficient reducing agent

A magnetic separation for processing iron from ore for the production of iron and steel has some problems fly ash as reported by Prakash successes to remove around such as high content of impurities mostly as silica, alumina 92 % iron using magnetic coating at up to 11.8 kG.3) and chromium oxide as well as nickel and cobalt

recovery of iron oxide from power plant fly ash by

recovery of iron oxide from power plant fly ash by

Removal of gangue materials, principally silica and alumina, from a magnetically-separated, iron-rich fraction of bituminous coal fly ash shows promise of yielding an iron ore grade concentrate. As separated, the iron-rich fraction contains 65 to 75 weight percent iron oxides or about 50% of the iron originally in the ash. Removal of the iron-rich fraction is a first step in several proposed processes for …
