In another study, Ezhov and Shvaljov (2015) used a laboratory-scale EVS-10/5 magnetic separator for dry beneficiation of iron ore of the Backer deposit. This was done by analysing the influence of the current strength in the electromagnet winding of the magnetic separator on concentrate yield and recovery. The authors concluded that increasing ...
The magnetic separator is a crucial apparatus used in the magnetic separation process [13].It works by making different magnetic materials follow different paths to achieve the separation effect [47].The sorted ore is fed into the sorting space of the equipment and is primarily subjected to the combined action of magnetic and mechanical forces, with the ore grains …
ABSTRACT. High intensity dry magnetic separators are in use for various applications in the mineral as well as coal processing industries. Evaluation of the performance of these separators treating different minerals has become an active research topic.
In recent decades, several kinds of dry magnetic separators were developed and reported effective for the pre-concentration of low-grade iron ores (Baawuah et al., 2020, Zhang et al., 2011, Zhao et al., 2017), and they have different magnet designs and may produce different separation characteristics.For instance, a dry magnetic separator with magnetic field …
