Pendahuluan:<\/strong> Magnetic separation is an important separation technology in the field of mineral processing and is widely used for the sorting and recovery of various types of ores. Whether it involves ferrous ores such as iron and manganese ores or the extraction of non-ferrous metals such as tungsten and tantalum ores, magnetic separation technology plays a crucial role. This article systematically summarizes the most common questions regarding magnetic separation technology to help you gain a comprehensive understanding of its principles, applications, and equipment selection.<\/strong><\/p>\n

\nChina is one of the earliest countries to understand the magnetic phenomenon. The ancient Chinese discovered that magnets can attract iron but not gold, silver, copper, or other metals. They also discovered the directivity of magnets and produced the earliest compass – Sinan.

1. What is Magnetic Separation?<\/h2>\n

A method of mineral separation in a non-uniform magnetic field based on the magnetic difference of various minerals.<\/p>\n

 <\/p>\n

2. What Are The Applications Of Magnetic Separation?<\/h2>\n

Pemisahan bijih logam besi (besi, mangan, kromium, dll.);
\nNon-Ferrous Metal<\/a> (tungsten, tantalum, etc.) and rare metals separation;
\nPemisahan bijih non-logam (asbes, berlian, kaolin, dll.);
\nPenghapusan komponen magnetik dari bahan padat dan limbah.<\/p>\n

3. What Is The Magnetic Separation Working Principle?<\/h2>\n

Di bawah aksi pembilasan dari aliran air, partikel-partikel bijih akan terlepas.
\nIn the magnetic field, the magnetic ore particles are aggregated to form a lump of magnetic material, which is attracted to the cylinder. As the cylinder rotates, the non-magnetic mineral, such as gangue, falls off, and the magnetic lump that is finally attracted to the cylinder surface is the concentrate ore. The concentrate goes to the edge of the cylinder, which has the weakest magnetic strength, and is discharged into the concentrate tank under the action of the flushing water. Non-magnetic or weakly magnetic minerals are left in the slurry and finally discharged, which are the tailings.<\/p>\n

4. What’s The Precondition of Magnetic Beneficiation?<\/h2>\n

(1) There must be an uneven magnetic field of sufficient strength and gradient.
\n(2) There must be a certain magnetic difference between the minerals, that is, the specific susceptibility of the two minerals is different.
\n(3) For minerals with strong magnetic properties, the magnetic force they receive is greater than the sum of various mechanical forces.<\/p>\n

Kondisi yang diperlukan untuk pemisahan partikel bijih magnetik adalah bahwa gaya magnetik partikel bijih magnetik harus lebih besar daripada gaya gabungan dari gaya mekanis yang berlawanan dengannya.<\/p>\n

 <\/p>\n

5. Why is Magnetic Separation Only In Non-uniform Magnetic Fields?<\/h2>\n

Dalam medan magnet yang seragam, bijih hanya mengalami torsi, sehingga arah sumbu panjangnya sejajar dengan arah medan magnet.
\nDalam medan magnet yang tidak seragam, partikel bijih tidak hanya dipengaruhi oleh torsi tetapi juga oleh gaya magnet. Partikel bijih diputar dan digerakkan ke arah di mana gradien medan magnet meningkat, dan akhirnya diserap pada permukaan kutub magnet.
\nDengan cara ini, partikel magnetik dengan sifat magnetik yang berbeda dipisahkan, sehingga pemisahan magnetik hanya dapat dicapai dalam medan magnetik yang tidak seragam.<\/p>\n

6. What is The Classification of Magnetic Minerals?<\/h2>\n

Mineral magnetik yang kuat<\/strong>: It is easy to pick out in a weak magnetic separator<\/a> with magnetic field strength H=900~1800Oe.
\nThere are a few such minerals, mainly magnetite, pyrrhotite, titanomagnetite, zinc-iron spar, and the like.
\nMineral magnetik yang lemah<\/strong>: In the magnetic field strength H = 6000 ~ 2000 Oersted, magnetic beneficiation is somewhat difficult, and some are easy.
\nMainly iron-manganese ore, hematite, specularite, limonite, siderite, rhodochrosite, etc.; some titanium, chromium, tungsten-containing minerals; biotite, hornblende, epidote, chlorite, olivine, garnet, pyroxene, etc.;
\nMineral non-magnetik<\/strong>: The magnetic separation method is not available currently.<\/strong>
