WEBAug 2, 2017 · Definition of CCR. In this study, we use the CCR [4], [5], [19] to evaluate the carbon efficiency of an iron ore sintering process. It was defined to be (1) C C R = m c / m s (kg / t), where m c is the amount (kg) of coke in the raw mix and m s is the amount (t) of sinter produced. So, the CCR can be reduced by decreasing m c and/or increasing m .
