Introduction. Demand for iron ore is strongly dependent on the steel industry, since nearly 98% of it is used in steelmaking (USGS, 2019). After the boom in prices in the commodities, pulled by the growth in steel production in China, there was a strong drop in iron ore prices caused by a significant increase in supply of this commodity in the market, besides a reduction in its demand.

2016-1-1 · HPGRs first made inroads into diamond processing (where rock fracture along grain lines favored a reduction in diamond breakage during comminution), and in the iron-ore industry. Over the course of the past 20 years, HPGR-based circuits have become a circuit commonly evaluated, and there are now many circuits in operation.
