The Iron Bridge project is a US$2.6bn investment in premium magnetite iron ore reserves with annual production, when the mine is fully operational, of 22 million wet metric tonnes per annum. Delivery of the first ore is expected in 2022. Responding to the award, Weir Group Chief Executive Officer, Jon Stanton said:

"The project's profitability was mainly a result of a strong iron ore price in the first half of 2019, as well as ongoing efforts to drive greater efficiency and reduce operating costs ...

The Minas-Rio Project that is being implemented by Anglo Ferrous Brazil, foresees the use of HPGR (High Pressure Grinding Rolls) to grind the undersize from screening at (-25.4 mm).

The HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process. The machine reduces particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed's density to 80% of its solid […]

The Dominga project is expected to produce 12Mt of iron concentrate and 150,000t of copper concentrate a year.

Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.

Testing confirmed that the ore that NioCorp expects to mine from the Project site, subject to receipt of necessary funding, can be successfully processed using HPGR technology, an …

Thyssenkrupp and Enter Engineering have signed an Agreement of Intent worth €50 million (US$58.5 million) on building an integrated mining metallurgical complex at Tebinbulak. The HPGR plant will be used to help process up to 60 million tons of iron ore per year, said the companies. The Tebinbulak deposit is located in the Karauzyak district ...

Within this highly-compressed bed of rock, an Enduron® HPGR delivers as much as 5N/mm in pressure, significantly reducing even highly-competent ores, such as diamond, gold, copper and coarse iron ore, while achieving throughputs of up 9,000 t/h that ball mills can't match.

Since the mid-1990s, HPGR were thought to be a prom-ising alternative for ball mill feed pretreatment. However, no sooner than by 2010, HPGR was the first time put in operation in hard rock crushing circuit at Penasquito project in Mexico (Fig. 4). HPGR Polycom-24/17 is entered in close-circuited

HPGR is being widely used typically in the cement, iron ore, diamond, and briquette sectors. Mining products such as metals are obtained thorough processing of materials extracted from the earth. Moreover, it is a highly energy-efficient technology and involves short-term exposure of raw materials such as iron ore to very high pressure.

The total estimated CAPEX for each circuit is within 14 percent, which infers that none of the options is a standout from a capital cost perspective at the accuracy level for this study. In comparison, the Boddington copper gold project CAPEX (Seidel et al. 2006) for the HPGR circuit option was 7 percent higher than the SAG option.
