The paper demonstrates the application of this methodology to optimize solids concentration in ball milling of an iron ore from brazil. the wet grinding experiments were conducted in bench 0.25 m diameter and pilot-scale mills 0.42 m diameter, and surveys in grinding mill.For the 2016 gold production quantity an energy input of 0.063 gj/t of ore material was necessary, after the figure of 0.072 gj/t in 2014. the energy intensity for gold production was 5.27 gj/oz in 2016 after 4.56 gj/oz in 2014. this means that the energy intensity increased over the two years with a grinding mill.Globally recognised as efficient grinding machines, they bring substantial improvement in profitability of concentrators. up to 40 higher energy efficiency 95 or greater uptime 50 less footprint vs ball mill in same application up to 50 less media consumption 2 weeks to install 85 db noise . open the catalog to page 4.

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.

Ore strength, and hard ore processing may consume up to 15 kw h/t of electric energy, while the energy consumption by hpgr is never more than 2.5–3.5 kw h/t even in grinding the hardest ores. nevertheless advantages and shortcomings of hpgr should be compared with sag mills in grinding mill.Grinding cost analysis. according to the relevant data analysis, grinding equipment has an impact on grinding cost and performance, accounted for 30 in overall mineral operating costs, accounted for 50 in whole grinding cost, so the grinding equipment has a great influence on manufacturing operating rates, total grinding efficiency and total operation cost.
