Dredging is another key mining method, often employed in coastal areas and riverbeds. This method involves using a dredge to extract the ilmenite-rich sands and gravels. The dredge sucks up the material, which is then processed on the dredge itself or transported to a processing plant. These mining methods require careful planning to minimize environmental impact and ensure the sustainable extraction of ilmenite resources.

Beneficiation: Separating Ilmenite from Other Minerals

After mining, the beneficiation process is crucial. This step involves separating ilmenite from other minerals present in the ore. Several methods are used, including gravity separation, which exploits differences in density. This method uses water or other fluids to separate heavier minerals like ilmenite from lighter ones. Magnetic separation is another key technique, which leverages ilmenite's weak magnetism. Magnets are used to attract and separate the ilmenite from non-magnetic minerals. Flotation is another commonly used method, in which chemicals are added to the ore slurry to selectively attach ilmenite to air bubbles. The bubbles then float to the surface, carrying the ilmenite, which is then skimmed off. These beneficiation processes are designed to maximize the concentration of ilmenite, making it suitable for subsequent processing and use.
