Partial reduction of particulate iron ores and cyclone ...

As mentioned in the referenced paper, high temperature entrained flow smelting (e.g. cyclone smelting) has been suggested as an alternative to bath smelting to use pulverized coal and dry iron ore concentrate. The application of cyclones to iron ore reduction was first attempted in 1955. The research was not successful and was terminated in 1966.

Process of producing pig iron from iron ore concentrate ...

We claim: 1. In a process for producing pig iron by reducing iron ore concentrate in which solid pre-reduced iron ore, coal, oxygen gas, and slag formers are injected beneath the surface of a molten iron bath contained in a reactor vessel, and react to produce said pig iron, slag, and exhaust gases including CO 2, CO, H 2 and H 2 O, the improvement comprising:

Process and apparatus for producing molten pig iron ...

A process for producing molten pig iron uses direct reduction of iron ore in a pre-reduction stage followed by a final reduction stage. In the pre-reduction stage iron ore is pre-reduced in a melting cyclone by means of a reducing process gas originating from the final reduction stage.

Ore Beneficiation - an overview | ScienceDirect Topics

Microbially induced iron ore formation has been confirmed at Gunma iron ore mine, Japan [21]. Ubiquitous microorganisms inhabiting iron ore deposits are useful in iron ore beneficiation (e.g., removal of alkalis, silica, clays, phosphorous, and alumina). Because the presence of phosphorous in the iron ore promotes bacterial growth (as an energy ...

EPO - Pig Iron production at a lower temperature

In 2001, Meijer and den Hartog created their CCF, which made it possible to produce molten pig iron directly from iron ore and coal using low temperatures through a two-step process using a melting cyclone for the pre-reduction stage and metallurgical vessel for the final reduction stage. Both stages make use of the gasses released during ...
