     298.23 Taconite and iron sulphides defined.  

    For the purpose of sections 298.23 to 298.28, "taconite" is 
 defined as ferruginous chert or ferruginous slate in the form of 
 compact, siliceous rock, in which the iron oxide is so finely 
 disseminated that substantially all of the iron-bearing 
 particles of merchantable grade are smaller than 20 mesh and 
 which is not merchantable as iron ore in its natural state, and 
 which cannot be made merchantable by simple methods of 
 beneficiation involving only crushing, screening, washing, 
 jigging, drying, or any combination thereof.  "Iron sulphides" 
 are defined as chemical combinations of iron and sulphur 
 (mineralogically known as pyrrhotite, pyrites or marcasite), in 
 relatively impure condition, which are not merchantable as iron 
 ore and which cannot be made merchantable by the simple methods 
 of beneficiation above described.
