Production of iron from iron ore (hematite & magnetite) - Cli Houston

The second is to make wrought iron or steel from pig iron by a further process. Blast furnace. Blast furnace is a type of metallurgical furnace used for smelting to produce metals, generally iron. 90% of all mining of metallic ores is for the extraction of iron. Industrially, iron is produced starting from iron ores, principally hematite.


Bioflocculation of Hematite and Goethite Using Bacillus licheniformis .

Cells and metabolite of Bacillus licheniformis were applied in the bioflocculation of hematite and goethite. Effects of bioreagent type, pH, and solid concentration on the settling process were studied. The highest settling of hematite and goethite were obtained at pH 5 and 7, respectively. This observation was in agreement.
