The selective extraction process ensures that magnetic minerals, such as magnetite, hematite, and ilmenite, succumb to the magnetic pull, separating them from their non-magnetic counterparts. This precision in separation not only enhances the purity of the final product but also maximises the efficiency of the overall mineral processing …

1. Introduction. China is one of the countries with abundant siderite resources and is also one of the largest producers of siderite in the world [1].In recent years, the demand for siderite has continued to rise with the over-exploitation of high-grade iron ore (hematite and magnetite) and the rapid development of the steel industry [[2], [3], [4]]. ...
Similar to the equipment used in wet minerals processing, Eriez uses drum, roll, pulley, and filter type magnetic separators in varying degrees of intensity to process dry minerals. These technologies rely on conveyors or feeders to present the material to the magnetic separator in an underbelt, overbelt, or gravity-fed configuration.
The complex mineralisation of these deposits does not allow for a significant opportunity to separate the titanium and magnetite minerals through normal physical upgrading processes. An upgrading ...
