Abstract
A method for the production of ore comprising a proportion of fines, additives and green agglomerates optionally containing a binder, provided with an outer coating consisting of a combustible containing fine-grained carbon, such as coke. According to the method, the ore is mixed with the additives and the optionally available binder. The mixture is pelletized and the green agglomerates thus formed are coated with the combustible, whereby the combustible is introduced into an agglomeration drum. In order to enable continual production of homogeneous-quality green agglomerates, the mixture is pelletized in the agglomeration drum and the combustible is added in an area of the longitudinal extension of the agglomeration drum where the size of the green agglomerates formed in the agglomeration drum is sufficient for further processing.
