Iron ore has been trading above $100 per tonne in June, while is also up 30% since the April's lows. Shutdowns of critical mines in key producing regions in the north and south of Brazil due to a surge in coronavirus infections has triggered worries of a supply crunch for the metal, while demand in China remained strong. Historically, Iron Ore reached an all time high of 200 in November of 2007.

1. Iron ore - supply and demand outline 1.1 Types of iron ore Iron ores can be classified in different ways. The most important has to do with the iron content. In many cases, ore with a total iron content of 60% to 63%, or greater, is regarded as high grade, and ore with a lower iron content is regarded as low grade.

FLOWSHEET OPTIONS CRUSHING FOLLOWED BY DUMP OR HEAP LEACHING WITH CYANIDE This method of gold recovery is the preferred method for treating low-grade gold ores because of its low cost. Between 10-20% of the gold recovered each year from primary sources is extracted by this technique. The advantages of this process are: • Simplicity

Apr 03, 2014· Low grade iron ores cannot be used as such for the production of iron and steel and need to be upgraded to reduce its gangue content and increase its Fe content. The process adopted to upgrade the Fe content of iron ore is known as iron ore beneficiation (IOB). ... A typical flow sheet for iron ore beneficiation plant is shown in Fig 1 ...

compare various options for treating the low-grade ore concentrate (Mwase, 2009). This proposed flowsheet has been conceptualised for integration into a standard platinum process which involves milling, flotation, smelting, acid pressure leaching of the matte and finally high pressure chloride leaching of high-grade PGM residue material.
