12 March 2015. It has now been several decades since the high-pressure grinding roll (HPGR) made its debut in mineral processing from its cement-based origins. With a number of hard-rock mining applications in large concentrators now several years into production, the time has come to break away from the concept of simply using HPGR in minerals ...

The material is fed to the HPGR by gravity and dragged into a compression zone between the rolls. The nip angle (α) represents the point in which the roller force starts acting on the material, thus starting the packed bed compression.The nip angle is dependent on the roller diameter and several material properties such as particle size and shape, …
Ilmenite Prices, Occurrence, Extraction, and Uses. Ilmenite, also known as titanium iron, titanium iron ore or by its synonym menaccanite, is a frequently occurring mineral from the mineral class of "oxides and hydroxides". It crystallizes in the trigonal crystal system with the chemical composition FeTiO3 and develops mostly thick tabular ...
How HPGR improves gold recovery. There are two main ways mines recover gold ore from the gangue, and HPGRs can assist with each process. One of them is heap leaching and for mines using this process, we've found that the most efficient setup is to have a HPGR perform tertiary grinding immediately prior to recovery, completely avoiding the use of a …
Ilmenite supplies Fe2O3 and TiO2. A natural source of titanium and iron, available in either powdered or granular form. Powdered ilmenite may be used as a colorant in glazes, and to seed crystals in titania glazes. Granular ilmenite is sometimes used in small amounts (<1%) to color/speckle clay bodies.

A supposed cubic form of ilmenite. Originally described from Jizerská meadow (Iser meadow), Jizerské Mts (Iser Mts), Liberec Region, Bohemia (Böhmen; Boehmen), Czech Republic. A Mg-Cr-bearing variety from DeBeers mine (kimberlites), associated, i.a., with hawthorneite. A ferrian magnesian variety of ilmenite.
Ilmenite can be used in small amounts (-1%) to produce dark brown specks in bodies and specialized glazes. It also is used in combination with rutile to develop characteristic rutile break glazes; it seeds crystals in titania glazes. If your production depends on consistency of this material, consider testing each batch of this material ...
The ilmenite used in this work is ∼95% pure with an average particle diameter of ∼170 μm (Sargeant et al., 2019a). The ∼45 mg ilmenite sample is placed into a ceramic tube and sealed onto the system at valve 7 using an O-ring tube fitting (Fig. 1). The ilmenite mass was selected as it is the approximate sample size for ProSPA ovens.

A second source of uneven feed to the HPGR can be segregation, where one side of the HPGR is mostly fed with coarser particles, while the other side receives more fines. Figure 3 shows a schematic illustration of feed segregation prior to the HPGR (Van der Meer & Maphosa, 2011). Similar to the impact of the uneven feed in the
