The raw chrome ore is the tailings after floating separation of platinum and palladium, and the grade of Cr2O3 is relatively high. 【X-ray diffraction analysis】 The main mineral ores in the chrome sample are chromite, enstatite, anorthite, hopfnerite, diopside, albite, biotite, etc.. 【Physical analysis】 The metallic minerals in the chrome samples …
The mining industry requires some powerful machinery – draglines, excavators, and massive drill rigs. You've likely seen one or more these machines while driving down the highway. It is a tough line of work that employs equally tough people, but as demanding as the industry is, and as imposing as most of the machinery tends to …
The magnetic particles are attracted to the matrix and are then carried outside of the magnetic field where they are subsequently flushed to the magnetic concentrate trough. The non-magnetic or less magnetic particles pass through the matrix through slots in the lower yoke to the non-magnetic collection hoppers. Applications

Low Intensity Magnetic Separators, LIMS, are designed to recover magnetic material from non-magnetic matter. The separators have modular design with several frames and process tank designs using a common magnetic drum for ease of selection of the best machine for each individual application.
Types of magnetic separators. ERGA produces more than 40 models of magnetic separators, which can be classified using the following parameters: >> Depending on the design >> Depending on the character of the medium for separation >> Depending on the type of magnetic system >> Depending on magnetic field intensity …
Gravity and magnetic separation. The first phase of the work, conducted at Mintek (Marape, 2020), focused on assessing to what extent the UG2 tailings could be upgraded by gravity or magnetic separation. Whilst the use of a shaking table was unsuccessful, a pilot Jones wet high intensity magnetic separator (WHIMS) proved to …
The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the …
The global demand for chromite, (Fe, Mg, Al)Cr 2 O 4, is driven by the need for ferrochrome to be used in wide applications for manufacturing different materials (Cramer et al. 2004).The chromite mining as well as the overall mining sector in South Africa has historically been a crucial factor in the economic growth and advancement of …
