SCREENING Screening involves physical sizing using openings through which particles will either pass though or not and therefore is based on geometrical size and shape only As particle and screen size gets smaller screening generally becomes more difficult and throughput capacity is lower Examples of screens are Grizzly screensThe taconite ore processing industry produces usable concentrations of iron bearing material by removing nonferrous rock gangue from low grade ore The six digit Source Classification Code SCC for taconite ore processing is 3 03 023 Table 1 lists the SCCs for taconite ore processing Taconite is a hard banded low grade ore and is
