Dry Iron Ore Processing. Dry processing at Vale. In the last 10 years, Vale invested almost R66 billion in facilities and development of technologies for the dry iron ore processing production. Today, most of our iron ore production (about 60%) is through dry processing. The natural moisture processing is used at Carajás and Serra Leste mines, at S11D Eliezer Batista complex, in Pará, and ...

During the wet processing, water is used to classify and purify the iron ore, removing impurities (such as silica) that affect the final product quality. Then, material must be exposed to moisture reduction processes in order to be stacked and transported to the clients. This processing route is used for the ore that has low iron content.

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). Ores are normally associated with unwanted gangue material. Grade of iron ore is usually determined by the total Fe content in the ore. Run of mines ores after dry or wet sizing, if it ...

Dry processing of iron ore presents an opportunity to eliminate costs and wet tailings generation associated with flotation and wet magnetic separation circuits. STET has evaluated several iron ore tailings and run of mine ore samples at bench scale (prefeasibility scale). Significant movement of iron and silicates was observed, with examples highlighted in the table below. The results of ...

Processing of the ore ranges from simple crushing and screening and separating various size fractions of the ore to the processes that beneficiate or upgrade the quality of the iron ore products. This is done by physical processes, which remove impurities by difference in particle density or size gravity or size separation. Processing may be wet or dry. Further ore handling, washing and ...

Dry processing is associated with the quality of the iron ore from the mine face. In Carajás, as the iron content is already high (above 65% Fe), the material is only crushed and screened to be classified by size (granulometry). In some mines of Minas Gerais, the average content is 40% Fe in itabirite. To increase its grade, the ore is concentrated through processing with water and the ...
