Our HPGR is a perfect complementary tool to work in conjunction with, and even enhance the performance of traditional grinding mills and fixed-gap crushers. The HPGR exposes feed material to very high pressure for a short amount of time. The compression typically causes the rock to crack and cleave along the grain boundaries, weakening the rock ...

HPGR should be a consideration for your heap leach flowsheet. The microcracking in HPGR product lends itself nicely to the heap leaching process. Cracking and cleaving along the particle grain lines, and the weakening of the rock structure increases exposure to the valuable ore particles, which enhances leaching kinetics.

In the present study, a novel process to prepare high-strength pellets of high-calcium, high-magnesium ilmenite concentrate was investigated. Magnetite concentrate and bentonite were selected as the additive and binder of the pellet, respectively. The effects of the magnetite concentrate content, bentonite content, and roasting temperature on the …
Ilmenite, otherwise called manaccanite, is a titanium-iron oxide mineral with formula: FeTiO3. It is a noteworthy wellspring of titanium. Typically thick and tabular, its crystals sometimes occur as thin lamellae (fine plates) or rhombohedra.. It can also be massive, or occur as scattered grains. Intergrowths with hematite or magnetite are ...

Physical Properties Of Ilmenite. Ilmenite is a black mineral found in mafic igneous rocks and pegmatites. It belongs to the iron titanium oxide minerals group, which also includes rutile, anatase, brookite, and perovskite. Ilmenite has a hardness of 5.5-6 on the Mohs scale, making it durable enough for use as an abrasive or gemstone polish.
