The influence of the magnetic induction and the cross slope of Franz-isodynamic separator were studied in a laboratory scale. Experiments with ore ground for different durations were made.
The new process can promote iron precipitate aggregation and growth on the surface of the magnetic iron ore seeds. A core-shell structure was formed of iron precipitate and magnetic iron ore seeds, which can be magnetized and coalesced in magnetic field, accelerating the solid-liquid separation.
The relevance of the paper is that dry magnetic separation (DMS) is the main beneficiation method of magnetite ores. The lack of efficient industrial-grade machines and apparatus for separating fine-grained magnetite ores means that DMS is used mainly as a pre-concentration operation for fairly large classes. The aim of the research is to …
The chrome ore washing plant mainly includes washing and gravity separation processes to extract high-quality concentrates. Magnetic separation technology is needed to remove impurities if the ore contains iron minerals. First, it must be washed, and the ore is separated from the mud by hydraulic flushing or additional mechanical scrubbing.

Dry medium-intensity magnetic separator (DMIMS) plays a vital role in enhancing the separation of low-grade raw magnetite ore. A good understanding of the dynamic separation process of DMIMS would further boost its economic competitiveness in minerals processing and engineering.
Conventional magnetic separation devices are widely used for the removal of tramp iron from a variety of feed materials and for the beneficiation of ferrous ores. These devices for separation of strongly magnetic materials employ a variety of mechanical designs. Recently developed high gradient magnetic separation devices extend the useful application of …
Chromium (Cr) ore refers to a natural mineral deposit that contains chromium in its raw form. Chromium is a chemical element with the symbol Cr and atomic number 24. It is a hard, lustrous, and corrosion-resistant metal that is widely used in various industrial applications due to its unique properties.
Chromite is an important commercial chromium-bearing mineral. It is an oxide of chromium and iron (FeO, Cr 2 O 3, or FeCr 2 O 4 ). A complex mineral containing magnesium, iron, aluminum, and chromium in varying proportions depending upon the deposit. Iron is replaced by magnesium, similarly chromium by ferric iron and aluminum. …
In chrome ore processing, a commonly used technology is gravity separation. Gravity separation is widely used in the processing of chromium ore due to its simplicity, economy and ability to efficiently separate chromite from gangue minerals based on the density of the mineral. The following will introduce you to the gravity separation …
More importantly, a relatively low pre-reduction temperature and selection of magnetic separation process were found to be more beneficial for chromium enrichment in slag; the highest chromium ...
The specific process is as follows: the chromite ore is ground to a qualified particle size and then enters into a strong magnetic separator for a rough separation.
