Title:
METHOD FOR PRODUCING BRIQUETTES FROM FINELY DISPERSED METAL OXIDES
Document Type and Number:
WIPO Patent Application WO/2003/004710
Kind Code:
A1
Abstract:
The invention relates to metallurgy and can be used for preparing iron-ore raw material for a subsequent reduction in blast and other furnaces, thereby replacing pellet and agglomerate. The inventive method for producing briquettes from finely dispersed metal oxides for reducing by heat treatment in a gas atmosphere consists in mixing the oxides with a water solution of liquid glass and hydrophobic liquid hydrocarbons at a boiling temperature higher than 300 °C and in pressing obtained product.
