Abstract:
A method for the production of self-reducing agglomerates for use in the production of metal comprising:mixing metallic oxide containing particles, and particles of a carbonaceous reducing agent with a pre-gel; introducing hot gas to said agglomerates at a sequentially decreasing temperature as the moisture content of said agglomerates decreases and the temperature of said agglomerates increases, wherein the temperature of the hot gas introduced to said agglomerates is controlled at a temperature to maintain the agglomerates below the combustion temperature thereof; thereafter curing said agglomerates by heating said agglomerates at a temperature of about 100 to 180Â° C. for about 10 to 60 minutes; and thereafter introducing said agglomerates to a reduction chamber for the production of methal therefrom.
