1. Introduction. High-intensity magnetic separation (HIMS) as an integral part of sorting paramagnetic materials has been widely used in different areas [1, 2], such as beneficiation of minerals [3], desulfurization of coal [4], non-metal ore purification [5], waste treatment [6], and nuclear fuel reprocessing [7].Over the span of decades, a …
This paper introduced the structure and working principle of a new high intensity wet permanent magnetic separator and its application on iron removal of a potash feldspar. …
In contrast, K-feldspar shape-fabric in an underground tunnel (∼660 m above sea level) shows complex variations in orientation and intensity. Magnetic fabric carried by coaxial contributions of biotite, magnetite, and maghemite is homogeneous along the examined section of the tunnel, and is decoupled from the K-feldspar fabric.
The relevance of the paper is that dry magnetic separation (DMS) is the main beneficiation method of magnetite ores. The lack of efficient industrial-grade machines and apparatus for separating fine-grained magnetite ores means that DMS is used mainly as a pre-concentration operation for fairly large classes.
Magnetic separation technology is a physical separation method that uses the differences in magnetism between matter to separate them from each other by different motion behaviors in a non-uniform magnetic field. It is highly efficient, green, and environmentally friendly, with little change in the physical and chemical properties of raw …
