Based on the properties, a high-gradient magnetic-separation process was introduced. After magnetic separation, chrysocolla was enriched into the magnetic concentrates with the weak magnetic limonite; this chrysocolla portion was more difficult to recycle, its proportion was higher, and it was encapsulated by limonite and biotite.

In this paper, a series of magnetic separation experiments and FEM-DEM simulations were carried to study the dynamic capture behavior of a dry magnetic separator (DMS) for biotite in fine aggregates. Experimental results show that the capture effect of a DMS on biotite in fine aggregates is greatly affected by the particle size.

Biotite is the phyllosilicate whose magnetic anisotropy is best known. Ballet and Coey (1982) studied the magnetic susceptibility of two biotite crystals. Measurements in two perpendicular planes gave the susceptibilities normal (k ⊥) and parallel (k ∥) to the crystal cleavage.Beausoleil et al. (1983) determined the magnetic behaviour of eight samples of …

This step separates magnetic (biotite, etc) from non-magnetic (muscovite, etc) flat particles. Use the Frantz Isodynamic Magnetic Separator up in the mineral separation lab across from the

High-intensity dry magnetic separation was used to remove deleterious components of the fine aggregates. 77–78% yield with good rejection of biotite, hornblende, kaolinite, …

The dry magnetic separation results showed that the amount of TiO2+Fe2O3 in the sample decreased from 2.50% to 0.06%. ... herewi th it was preferred acidic anionic method in order to take biotite ...

The present work demonstrates the improvement in the characteristics of three manufactured fine aggregates through dry rare-earth magnetic separation. It demonstrates that the mica/biotite content has been reduced significantly, leading also to …

In this study, magnetic separation was used to remove excess biotite from manufactured sand and to realize the upgrade of manufactured sand, and a series of …

The study provides a new liquid magnetic separation (LMS) technique for concentrating sand-sized iron-bearing minerals, in general, and for quantitative isolation of biotite, in particular, …

The presence of iron-bearing minerals like biotite, tourmaline, and other amphiboles or pyroxenes, can be an obstacle in producing concentrate grading >6% Li 2 O and <1% Fe 2 O 3 if they cannot be sufficiently rejected from the flotation feed with magnetic separation. While biotite rejection is targeted during mica flotation, Fe-Al silicates ...

The anisotropy of magnetic susceptibility (AMS) of single crystals of biotite, muscovite and chlorite has been measured in order to provide accurate values of the magnetic anisotropy properties for these common rock-forming minerals. The low-field AMS and the high-field paramagnetic susceptibility are defined. For the high-field values, it is necessary to …

In the past, separation processes such as gravity separation, flotation separation, magnetic separation and wind separation have been generally adopted [11–15]. For example, the use of magnetic separation technology to extract biotite from mill tailings was reported in the aggregate production system of China's Three Gorges Project in 1987.
