Karara comprises a large-scale, long-life magnetite orebody amenable to bulk mining and processing. Magnetite ore has lower iron content (34-36% Fe) than hematite ore (58-64% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to produce a high-grade (+65% Fe) concentrate for steelmaking.

Mining method and ore processing. The Poltava mine is an open-pit mining operation involving the usage of excavators and haul trucks to deliver high-grade magnetite iron ore to the processing plant located adjacent to the mine. The processing plant has a nameplate capacity of 35 to 40Mt of ore based on the types of ore processed and pellets ...
Alumina levels range from 5.9% to 8.8% and are reduced to 2.8% after processing. The iron ore wash plant also removes clays from the feed material and the combined effect means the Fe content increases from between 43.4% and 52.7% in the feed to above 60% iron ore product, with a yield of up to 50%.
Sedgman was awarded a contract for the design and construction of a 7.5 Mt/a (run-of mine (ROM) feed) modular iron ore processing plant at Fortescue Metals Group Solomon iron ore mine. The modular iron ore processing plant was an important element in Fortescue's vision of operating the Solomon mine without the need for a new wet plant at the ...
The processing methods largely depend on the characteristics of the ore itself and the nature of association of gangue with the ore. This chapter will try to give an overview of important aspects involved in iron ore processing including iron ore mining, iron ore handling, and iron ore beneficiation and agglomeration.
At the processing plant, the taconite is crushed into very small pieces by rock crushing machines. The crushers keep crushing the rock until it is the size of a marble. The rock is mixed with water and ground in rotating mills until it is as …

4.1.1 Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or open-pit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions. Small, low-capacity mines have rapidly disappeared.
