A multiobjective model, based on the Souza et al. (Citation 2010) model, was proposed to maximize production and minimize the deviation from the feed rate of processing plants and crushers, as well as the total travel time of the shovel. They tested the model in a case study of an iron ore mine.

The life of the mine is a key element in the design of any crushing plant. Shortterm mine lives (three to eight years) require a very careful approach to design, layout and construction. Since the crushing plant's structure and enclosure can represent the largest single cost element in a primary crushing plant, it is imperative to optimize ...

WHIM is the short acronym for Wet High Intensity Magnetic Separation . At present, most iron raw materials are produced from magnetic taconites, which are ground to a nominal minus 270 mesh (53 micrometers), beneficiated by wet lowintensity magnetic separation, and pelletized. The taconite ore bodies generally contain 19 to 25 percent ...

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.
