difference between washing and screening of iron ore
The per cent of iron in the ore as mined must be not less than 50%, if it is to be used without being first improved (beneficiated) by cobbing, washing, calcining, or magnetic concentration. Leaner ore is found in very large quantities; and in a favorable situation, it may be workable by some concentrating process.

Ore, Rock & Aggregate Screening (Complete Guide)
· A-Z Guide to Screening Ore, Rock & Aggregate. A simple definition of a "screen" is a machine with surface (s) used to classify materials by size. Screening is defined as "The mechanical process which accomplishes a division of particles on the basis of size and their acceptance or rejection by a screening surface".
· 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.
