Magnetite Ore Cluster Hydrocyclone Mining Equipment Mineral Processing Principle overview. The ore pulp enters the shell along the involute direction through the ore feed pipe under pressure, and makes a rotary motion in the shell.
Lower metal recoveries were obtained when processing the lower density magnetite. AB - Simulations were performed for various hydrocyclone staging arrangements using experimental results from single-stage wide-angle hydrocyclone separations when processing fine (-150 μm) particles in a 25 mm diameter hydrocyclone.
Compared with a conventional hydrocyclone, this magnetic hydrocyclone is approximately 13% more efficient in the recovery of magnetite, with no change to the liquid content of the product. In an appropriate industrial application, the use of this type of magnetic hydrocyclone could produce significant reductions in the size of installation and ...

Microsand and magnetite are commonly used, which act as a seed in ballasted floc. The recovery of the ballast in BF process can affect the operating cost. In this study, we evaluate various sizes of magnetite particle with a specific gravity of above 5 in order to apply the hydrocyclone as a ballast recovery system in the BF process.
Fig. 1 shows the schematic of a 75 mm hydrocyclone test rig used for the experimental studies. The non-spherical shaped silica and magnetite particles, having 90% passing through 88 µm are used as the feed material. The densities of silica and magnetite are calculated using the Pycnometer as 2650 and 4500 kg/m 3 respectively. Fig. 2 displays ...
The structure of the hydrocyclone is relatively simple. Its upper end is a cylindrical part, and its lower part is a conical container. The slurry is fed into the cyclone at a certain speed (generally 5 to 12 meters per second) along the tangential direction, and obtains a rotary motion, thus generating a large centrifugal force (usually tens of times or even hundreds of times greater …

A magnetic hydrocyclone can be used to classify mill waste in order to prevent overgrinding of released magnetite grains excluding the return of coarse particles to the mill. A magnetic field of 5–10 T can be applied in MHC to extract weakly magnetic minerals (ilmenite, hematite, etc.) [ 1 ].
However, hydrocyclone designs are constantly being improved and are becoming more science-intensive and com-plex [4][5][6][7]. Thus, for example, one areas of research is …
Such comprehensive research has not been undertaken in the literature although individual assessments were completed.

Magnetite concentrates have more predominance due to the heat released by oxidation during roasting and reduce energy consumption (Jiang et al., 2013). Magnetite oxidation is an exothermic reaction, releasing about 120 kJ/mol, according to the reaction shown in Eq. (3) (Meyer, 1980). (3) 4 F e O F e 2 O 3 (s) + O 2 (g) → 6 F e 2 O 3 (s)
