Dry electrostatic processing of iron ore presents an opportunity to reduce costs and wet tailings generation associated with traditional gravimetric, flotation and wet magnetic separation circuits.

The mining industry has seen several significant dam failures in recent years. Dam failures are associated with errors in design, implementation, operation, and monitoring (Azam, 2014, [2]).Dewatered stockpiling (dry stacking) is a safer alternative to tailings dams (Rico et al., 2008, [3]) for tailings disposal; however, this method has not yet been used in iron ore mines …

The iron ore industry has reached the end of an unprecedented period of expansion triggered by China's demand for iron ore. Lower ore prices have led producers to focus on optimising mining operations while extracting the maximum tonnage from the infrastructure presently in place or from projects already underway. A rising global surplus is expected to …

The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, …

Iron ore magnetite processing (LIMS, MIMS, WHIMS, Davis Tubes) The increased worldwide demand for steel in recent decades has led to an increase in the exploitation of magnetite iron ore deposits as an alternative to hematite …

Dry processing of iron ore: In dry processing of iron ore, ROM is generally crushed below 40 mm through three-stage crushing and thus segregated by screening into 10–40 and −10 mm fractions. For softer ore, tumbler index is generally low and hence lump ore is crushed below 10 mm to produce fine product. Yield from the plants has been ...

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.

The magnetite beneficiation process The degree to which an iron ore is processed depends mainly on the iron ore products being made. The most common iron ores on the market are lump ore, sinter fines and iron ore pellets/pellet feed. Which products are suitable for a mine is dictated by the ore's liberation characteristics and market demands.
