A method of producing an iron ore briquette that is suitable for use as a blastfurnace or other direct reduction furnace feedstock which includes the steps of: (1) mixing ore and a flux to form an ore/flux mixture (2) pressing the ore/flux mixture into a green briquette using a low roll pressure; and (3) indurating the green briquette to form a fired briquette.
La présente invention concerne un procédé pour produire une briquette de minerai de fer adaptée à un usage comme charge d'alimentation dans un haut fourneau ou dans tout autre four à réduction directe. Ce procédé consiste (1) à mélanger du minerai et un flux, afin de former un mélange minerai/flux, (2) à comprimer ce mélange minerai/flux, afin de former une briquette crue, par utilisation d'une faible compression par cylindre, puis (3) à faire durcir cette briquette crue, afin de former une briquette cuite.
