Iron Ore Beneficiation and Tailings Treatment Operations

Process monitoring and control in beneficiation operations constitute a critical component of automation, involving numerous parameters of complex and diverse natures. At this stage, iron ore undergoes classification by a classifier and concentration by a collector to produce iron concentrate. Actual processing methods include gravity separation, magnetic separation, and flotation. For special iron ores like hematite and magnetite, combining different processing techniques during actual operations ensures rational selection, thereby enhancing the efficiency of iron ore beneficiation.

Typically, tailings contain unrefined ore, waste rock, and impurities. To prevent severe ecological damage, these tailings require processing to ensure resource efficiency and avoid substantial waste. During tailings processing, personnel can transport tailings to tailings storage facilities or tailings ponds. Chemical and physical methods are then applied to reduce moisture content, preventing suspended particles from migrating and damaging ecosystems due to excessive water content. To enhance treatment efficacy and mitigate the hazards of solid waste, techniques such as sedimentation and filtration can be employed to remove suspended solids and moisture from tailings. This approach reduces tailings volume, thereby minimizing the space required for their management. To prevent the leaching of harmful substances from tailings, protective measures such as covering can be implemented. This safeguards both soil and groundwater in the tailings area, minimizing environmental damage to surrounding regions.
