PROBLEM TO BE SOLVED: To provide a treatment method for crude ores which enables the resource recovery of ores alternately stratified with argillite and hematite as the crude ores.;SOLUTION: After the crude ores alternately stratified with the argillite and the hematite are subjected to primary crushing, the primary crushing products are subjected to secondary crushing while the density thereof in a crushing chamber is increased and the argillite is preferentially crushed. Also, the secondary crushing products are similarly subjected to ternary crushing and the ternary crushing products below prescribed grain sizes are compressed under a prescribed force in a comminution chamber having a spacing sufficiently wider than the grain sizes thereof, by which only the argillite is comminuted.;COPYRIGHT: (C)2003,JPO
