The sticking phenomenon accompanying reduction of iron ore pellets under load was investigated and was found to be dependent on temperature, chemical composition and applied load. The experimental results were analysed to investigate the reduction kinetics and mechanism of iron ore pellets under controlled conditions of …
et al.[27] investigated the influence of iron ore concen-tration and temperature on the reduction behavior of iron ore and biochar composite pellets. Interestingly, the authors studied reduction reaction in terms of produced CO and CO 2 gas during reduction. The authors varied the carbon to iron ore mole ratio in composite pellets
When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.

ABSTRACT. The behavior of iron ore pellet binders is complex. Any pellet binder is subject to a handful of practical requirements: that it be readily dispersed through a pellet, that it effectively controls the movement of water within the pellet, and that it contributes to the inter-particle bonding within the pellet.
