摘要
A pyrometallurgical reductive process characterised in that firstly pellets comprising a mixture of ore and coke precursor are heated in the absence of air so that the coke precursor is converted to coke and secondly the so formed pellets are treated in a subsequent reductive step to obtain as product discrete pellets comprising reduced ore set in a matrix of coke. Preferably the matrix of coke is in the form of an external coating to the pellet.
