Mining operations usually provide ore of varying characteristics. At the Donganshan Sintering Plant, the ore is a low-grade, complex, hard-to-separate carbonate containing iron ore, and a two-step flotation circuit was previously developed to overcome the negative impact of the carbonates on the reverse flotation process. However, with the further …

The type of beneficiation employed depends on the physical and mineralogical properties specific to each iron ore deposit. Iron ore processing involves a series of steps to extract and refine iron from its ore deposits. The first stage is mining, where large-scale open-pit or underground operations extract iron ore from the Earth.

Selective flotation of minerals is a separation method based on differences in surface properties of minerals. An auxiliary pretreatment on minerals, prior to flotation, can help to increase the selectivity of separation process. Surface dissolution is a pretreatment process modifying surface properties of minerals.
