A new cold bonding technology for producing coal bearing composite pellets was developed. Alumina cement was used as binder, which gave high mechanical strength to the pellet even at elevated temperatures. Laboratory test results showed that the metallisation rate of the pellets was high owing to the intimate contact of the particulates of coal and the iron ore in the pellet. The developed cold bonding method can also be used to recycle electric arc furnace (EAF) dust, from which valuable zinc and lead can also be recovered.
A new cold bonding technology for producing coal bearing composite pellet was developed. 1 Laboratory tests showed that the cold bonded pellet has enhanced mechanical strength, from which good quality DRI can be produced. Based on the laboratory test results, a rotary kiln process was designed for producing DRI. Because of the high metallisation rate of the pellets and the corresponding novel operation conditions, the proposed rotary kiln process has significantly higher energy efficiency than the SL/RN process, hence emitting less CO 2 .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
