A two-stage magnetic separation process (HIMS and LIMS) allows the uncovered ore grains to be separated from the concentrate obtained after hydrocycloning. Moreover, during the process of separation at low intensive magnetic separation (LIMS), chromites are separated from the non-magnetic fraction that contains both gold and silicates.

Five Common Gold Separation Methods You Have to Know - Xinhai. Magnetic separation is the process by which magnetically susceptible material is separated from a mixture by the application of a strong magnetic field. Iron ores are usually subjected to the magnetic separation process, due to the high magnetic susceptibility of iron.

A dry high-intensity magnetic separator is a waterless separation machine introduced to separate weakly magnetic particles that DLIMS cannot process. This technology employs a greater magnetic field strength provided by an induced or permanent magnet to separate the materials based on their magnetic susceptibility [ 21, 22 ].

Abstract. Magnetic separations are probably one of the most versatile separation processes in biotechnology as they are able to purify cells, viruses, proteins and nucleic acids directly from crude samples. The fast and gentle process in combination with its easy scale-up and automation provide unique advantages over other separation techniques.

9.2.2.1. Iron minerals. Based on the magnetic susceptibility values in Table 9.1, iron minerals can be divided into two groups, namely strong magnetic minerals, that is, magnetite (72.4% Fe), and weakly magnetic minerals, that is, martite (70.0% Fe), hematite (70.0% Fe), specularite (70.0% Fe), limonite (57.14–59.89% Fe), and siderite (48.2% …
