Per NCCI's Scopes Code Description:
Code 1452 is applied to all employees engaged exclusively in the milling of coarse ores. The operations involve crushing, screening, washing, amalgamation or flotation and drying to obtain concentrated ores of metals. The milling of ores to recover some nonmetallic minerals which do not require amalgamation or flotation also falls within this classification. The manufacturing of natural graphite, i.e., the extraction of graphite from graphite rock, is also classified under Code 1452. This involves crushing, milling, pulverizing, flotation and drying operations.
