Roasting or calcination of the ore oxidizes some of the sulfur, phosphorus and arsenic impurities. Sulfur oxide is volatile and evaporates off or is washed out. Iron is mainly extracted from hematite (Fe 2 O 3) and magnetite ores. Natural or direct shipping iron ores contain between 50-70% iron and can be fed directly into the blast furnace.
The three primary and secondary crushing stations each crush 5000 tons of ore an hour (t/h) into particles smaller than 150 mm. This material is then conveyed to a 250,000 t surge stockpile prior to being fed into the processing plant. When the ore is fed into the processing plant it first enters the scrubbers, before being sent to wet screening.

By Keith Vining. CSIRO can help you manage unplanned processing incidents. At Iron Ore 2017, a common concern across the industry was managing the short-term variability of ore characteristics within deposits in iron ore processing, the flow-on effects of unplanned processing issues, and the resulting downtime across the production cycle.
Manganese is considered a relatively rare metal as concentrations of it in ore of commercial importance are geographically limited. In nature, manganese is found in the form of oxides, carbonates, and silicates. Manganese ores are complex in the sense that they not only consist of a complex oxide mineral assemblage but these minerals are also very finely inter …

The main Carajás plant, Plant 1, is in the process of conversion to natural moisture: of the 17 plant processing lines, 11 are already dry and the remaining six wet lines will be converted by 2022. Serra Leste's treatment plants in Curionópolis and S11D in Canaã dos Carajás also do not use water in ore treatment.
Iron ore processing. For iron ore extraction, the iron ore processing plant receives ROM where it undergoes crushing and subsequent screening on a grizzly screen. It is then sized and above cut point ore sent for further crushing and additional sizing; Coarse material has tramp removed via an overbelt magnet and into a DMS drum
In December 2018, Vale spent US$500 million to acquire New Steel, which developed a widely patented technology for processing dry iron ore. Montenegro told Reuters that many of the state's wet concentration units have declining assets, and mines with an average iron content of 40% need some form of processing to extract value.

Iron processing - Smelting, Refining, Alloying: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.
