High-pressure grinding rolls (HPGR) have gained great popularity in the mining industry in the last 25 years or so. One of the first successful applications of the technology has been in iron ore pressing prior to pelletization. Piston-and-die tests can provide good insights on the material response in an HPGR. This work analyzed …

Iron ore concentrates are ores that have been mechanically processed to increase their iron content and decrease impurity levels. Iron is not a rare commodity – it's the fourth most abundant element in the earth's crust, making up around 5% – but zones that can produce high-quality DSO are finite. Thankfully, there are ample resources ...

In the carriage of iron ore, the following precautions should be taken: Iron ores are heavy cargoes which occupy a small area for a large weight, ie they have a low stowage factor (between 0.240.80 m3/tonne). It is therefore important that the tanktop has sufficient strength to carry certain iron ores. trimming of these cargoes is generally ...

An iron ore concentrate from the Iron Quadrangle area (Minas Gerais, Brazil) has been selected for the study. It is essentially composed of hematite with minor amounts of quartz as contaminant. Pilot-plant experiments have been conducted at a pilot-plant HPGR, which consists of a studded roll with 0.32 m in width and 1 m in diameter.
