A Novel Pneumatic Planar Magnetic Separator for Magnetite …

In the mineral processing industry, dry magnetic separation is commonly used for removing tramp metals and the coarse cobbing of magnetite ores [11,12]. …

Magnetite Concentration Methods

Magnetic cobbing has been successfully applied in both countries, and produces excellent results with ores which carry magnetite in large pieces, and in which …

Developments in the physical separation of iron ore: …

During the roasting process, siderite (FeCO3) transforms to magnetite (Fe3O4) along with producing carbon monoxide (CO), but hematite (Fe2O3) needs CO …

Assessing the performance of a novel pneumatic magnetic …

Song et al. (2019) investigated the use of a fluidised dry magnetic separator to purify and recover magnetite powder from a mixture of magnetite powder and coal powder and …

KM C364e-202

FIG 2 — Three magnetite concentrate particles from the first magnetic cobbing stage, each containing the three dominant non-magnetic minerals (quartz, carbonates and iron …

Dry Magnetic Cobbing Separation

Evaluation of the benefits of cobbing may or may not be simple. Cobbing is usually justified: 1. When a high percentage of the crushing plant feed can be rejected at a coarse size with little loss in values. 2. When a final product perhaps premium priced, can be removed from the circuit … See more

Intensity Magnetic Separation

Dry low-intensity magnetic separation is confined mainly to the concentration of coarse sands which are strongly magnetic, a process known as "cobbing," and is often carried …

Electromagnetic Separators for Strongly Magnetic Minerals

This machine is used for cobbing ores which are not necessarily dry; the ore fed is coarse (1½ ins.) and the separator puts through a large tonnage with the idea of …

Magnetite Beneficiation: A Focus on Flowsheet …

In the present study, we have extended the studies on the PMS with the focus on investigating how various PMS processing flowsheet configurations influence …

MAGNETIC BELT COBBING TECHNO·LOGY FOR …

Field cobbing of the test materials produced an enriched iron ore concentrate and a low-grade reject material. Successful ore separation and enrichment occurred with both …
