Introducci\u00f3n:<\/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

Separaci\u00f3n de minerales ferrosos (hierro, manganeso, cromo, etc.);
\nNon-Ferrous Metal<\/a> (tungsten, tantalum, etc.) and rare metals separation;
\nSeparaci\u00f3n de minerales no met\u00e1licos (amianto, diamante, caol\u00edn, etc.);
\nExtracci\u00f3n de componentes magn\u00e9ticos de materiales s\u00f3lidos y residuos.<\/p>\n

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

Bajo la acci\u00f3n de lavado del flujo de agua, las part\u00edculas de mineral se sueltan.
\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

La condici\u00f3n necesaria para la separaci\u00f3n de las part\u00edculas magn\u00e9ticas de mineral es que la fuerza magn\u00e9tica de las part\u00edculas magn\u00e9ticas de mineral sea mayor que la fuerza combinada de las fuerzas mec\u00e1nicas opuestas a ella.<\/p>\n

 <\/p>\n

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

En un campo magn\u00e9tico uniforme, el mineral s\u00f3lo est\u00e1 sometido a torsi\u00f3n, de modo que la direcci\u00f3n de su eje longitudinal es paralela a la direcci\u00f3n del campo magn\u00e9tico.
\nEn un campo magn\u00e9tico no uniforme, las part\u00edculas de mineral no s\u00f3lo se ven afectadas por el par, sino tambi\u00e9n por la fuerza magn\u00e9tica. Las part\u00edculas de mineral giran y se desplazan en la direcci\u00f3n en la que aumenta el gradiente del campo magn\u00e9tico, y finalmente se absorben en la superficie del polo magn\u00e9tico.
\nDe este modo, las part\u00edculas magn\u00e9ticas con diferentes propiedades magn\u00e9ticas se separan, por lo que la separaci\u00f3n magn\u00e9tica s\u00f3lo puede lograrse en un campo magn\u00e9tico no uniforme.<\/p>\n

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

Minerales fuertemente magn\u00e9ticos<\/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.
\nMinerales magn\u00e9ticos d\u00e9biles<\/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.;
\nMinerales no magn\u00e9ticos<\/strong>: The magnetic separation method is not available currently.<\/strong>
\nHay muchos minerales de este tipo, entre ellos:<\/strong><\/p>\n
