2020-11-1  1. Introduction. Iron ore sintering is an important hot agglomeration pre-process for ironmaking in most integrated steel mills. This process converts a mixture of ore fines, fluxes, return fines and plant dust to sinter by partial melting and re-solidification of the granulated particles in a moving grate, in which the coke breeze is typically used as solid fuel with mixing ratios of 3–5 wt ...

Agglomeration technique improves heap leaching process ...

2018-7-5  In addition to creating a more permeable heap, agglomeration offers another advantage: a jump start to the leaching process. By incorporating the leaching agent into the agglomeration stage, the ore fines and leaching agent are homogeneously mixed. This provides an early start to the leaching process and helps to ensure a uniform dispersion of ...
