During this step a combination of matte, a mixture of copper, sulfur and iron, and slag, a dense, glassy material made of iron, silica, and other impurities, is produced. The copper matte contains 58-60% copper at this point. The molten matte is then taken to another furnace (a converter) to have the remaining iron and sulfur removed.

Iron ore is an important raw material for steel production enterprises. In most cases, iron ore with a grade of less than 50% requires ore beneficiation before smelting and utilization. Natural ore (iron ore) is gradually selected for iron through procedures such as crushing, grinding, magnetic separation, flotation, and gravity separation.

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

Abstract A new process is developed for metallurgical beneficiation of iron laterite nickel-containing (limonite) ores with the formation of a metallic nickel–cobalt concentrate. This process includes reducing roasting of the ores with sulfur-containing additions in the temperature range 1100–1200°C, the fragmentation of the roasting product, and the magnetic separation of metallic and

Beneficiation = Improve Concentration of Iron. Ore is either Hematite (Fe2O3) or Magnetite (Fe3O4) and the iron content ranges from 50% to 70%. This iron rich ore can be charged directly into a blast furnace without any further processing. Iron ore that contains a lower iron content must be processed or beneficiated to increase its iron content.
