Abstract
A method of producing an iron one briquette that is suitable for use as a blast furnace or other direct reduction furnace feedstock which includes the steps of: (1) mixing: (i) ore having a predetermined particle size distribution with a top size of 4.0 mm or less; and (ii) a flux; to form an ore/flux; (2) adjusting the water content of the ore prior to or during mixi ng step (1) to optimise briquette quality and product yield; (3) pressing the ore/flux mixture into a green briquette; and (4) indurating the green briquette to from a fired briquette.
Claims (40)
1. A method of producing an iron ore briquette that is suitable for use as a blast furnace or other direct reduction furnace feedstock which includes the steps of:
(a) mixing: (i) ore having a predetermined particle size distribution with a top size of 4.0 mm or less; and (ii) a flux; to form an ore/flux mixture;
(b) adjusting the water content of the ore prior to or during mixing step (a) to optimise briquette quality and product yield;
(c) pressing the ore/flux mixture into a green briquette; and (d) indurating the green briquette to form a fired briquette.
(a) mixing: (i) ore having a predetermined particle size distribution with a top size of 4.0 mm or less; and (ii) a flux; to form an ore/flux mixture;
(b) adjusting the water content of the ore prior to or during mixing step (a) to optimise briquette quality and product yield;
(c) pressing the ore/flux mixture into a green briquette; and (d) indurating the green briquette to form a fired briquette.
2. The method defined in claim 1 further includes crushing and screening ore to form the predetermined particle size distribution that is mixed with flux in step (a) .
3. The method defined in claim 1 or claim 2 wherein the top size of the predetermined particle size distribution of ore that is mixed with flux in step (a) is 3.5 mm.
