Screening is the passing of material through definite and uniform apertures is the only true and accurate means of grading to a required particle size. Air separation and hydraulic classification depend upon gravity and particle shape, and result in the segregation and retention of material of higher specific gravity and lower surface area irrespective of size.

Jan 04, 2007· N. Haque, T. Norgate, in Iron Ore, 2015. 20.2.5 Screening and separations. Screening is an important step for dry beneficiation of iron ore. Crushing and screening is typically the first step of iron ore beneficiation processes. In most ores, including iron ore, valuable minerals are usually intergrown with gangue minerals, so the minerals need ...
The processing of iron ore requires physical processes that help ensure conformation to sizing specifications and where required help the ore achieve grade targets. The sizing separation of iron ore is achieved through the comminution and screening processes described in Chapter 8.

The use of sensor-based XRT ore sorting converted uneconomic waste material into economic ore, according to TOMRA’s Robben, meaning material below the cutoff grade for the mainplant, set at 0.9% Sn in 2014, was able to be treated with lower specific operating costs, thus bolstering reserves.
The crushed iron ore will be transported by an overland conveyor to a new 80Mtpa iron ore handlingplantat the Mining Area C hub, for processing. The new ore handling facility will house crushing, screening, separate stockpiling facilities for iron ore lumps and fines, and train load-out facilities.
