Description of Iron Ore Concentrate. Iron ore concentrate is produced from the magnetite iron ore in the beneficiation process. When the iron ore is mined, first it will be crushed by a crusher, after a preliminary screening, it is sent to the large gyrator crusher, and then the broken materials will be sent to the concentrator for grinding, separating, and concentrating, After fine grinding ...
