Hence, the direct flotation method is introduced to concentrate apatite from phosphate ores to remove dolomite and Fe-bearing minerals and silicate minerals. However, the similar interfacial properties of apatite and dolomite normally lead to the difficult separation between these two minerals when using fatty acid as the collector [32], [33].
A magnetic separator is a piece of equipment that magnetically attracts and removes foreign metal pieces from other materials. They are typically installed in a line of flowing materials and can be used in conjunction with metal detectors and x-ray machines for maximum defense against contamination and damage to expensive equipment.
Magnetic Separation is the process of removing ferrous metal contaminants from a flowing product. Removal of this metal contamination (also known as tramp metal or tramp iron), is essential in order to safeguard your product purity and also protect your processing equipment from costly damage. Stray nuts and bolts, pieces of wire, spanners or ...
This work investigated the use of a wet high intensity magnetic separation (WHIMS) in conjunction with gravity pre-concentration steps (Knelson and Falcon centrifugal concentrators) to beneficiate a rare earth ore.

Magnetic separation is widely used in rare earth mineral beneficiation to separate paramagnetic rare earth minerals from heavy ferromagnetic impurities. Paramagnetic minerals such as monazite and xenotime are separated by using different types of magnetic separators (Gupta and Krishnamurthy 1992 ).
The differences in magnetic susceptibility can be utilized to separate a valuable mineral from its gangue through the magnetic separation method. Similar to other materials, minerals are generally classified into three main categories, namely diamagnetic, paramagnetic, and ferromagnetic. Among these subgroups, ferromag-netic minerals …
The microflotation test results showed that GG had a good inhibition effect on the dolomite flotation and could realize the separation of brucite and dolomite. Generally, the separation performance of flotation reagents is closely related to the hydrophobicity of reagents acting on the mineral surfaces [40].
Magnetic Separators use a magnetic field to automatically sort non-ferrous and ferrous materials. These self-cleaning magnets remove tramp iron and purify material conveyed in bulk form. Magnetic Separators can replace or retrofit existing equipment to turn your material handling conveyor into a material separation conveyor.
In this work, HEDP was first introduced as a dolomite depressant to improve the flotation separation of magnesite from dolomite in the NaOl system. We found that a novel reagent scheme of HEDP (200 mg/L) and NaOl (120 mg/L) can realize the selective flotation of magnesite from dolomite at approximately pH 10.
