The HPGR rolls have 650 mm width and 1100 mm diameter. Based on the primary plant design, it is expected that the mean size of the HPGR products would be around 8 mm. The database was collected from the monitored HPGR operation parameters for around one year (from 24 March 2018 to 19 March 2019–266 records).

Liberation degree of −19 + 11 μm by the MLA of the HPGR products (a) and JC products (b). The argillation of iron oxides during the stage grinding and stage separation of the ilmenite in the JC product is more severe than that during the parallel separation of Fe – Ti in the HPGR product. Besides, the flotation rate and recovery of ilmenite will …

The results showed that the HPGR-ball mill circuit achieved a 21% reduction in energy consumption over the existing SAG-ball mill circuit at the same P80 grind size of 160 mircons (μm). At a grind of 80% passing 75 μm, the HPGR-stirred mill circuit showed a 34% reduction in energy compared to the base case.

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 crystals, but also granular to massive aggregates in ...

The high pressure comminution process causes micro-cracks in the particles, which lead to the liberation of minerals and a higher portion of fines. HPGR treated minerals show better leaching performance, because the micro-cracks increase the particle contact surface for the leaching liquid. Also, flotation efficiency is further enhanced through ...
