Angang Group overcame the difficult problem of roasting ultrafine concentrate.

On the 15th, it was learned from Ansteel Group that Ansteel Group Mining Co., Ltd. has collaborated with multiple engineering and technical units as well as universities to overcome the key technologies of "ultrafine magnetic/hematite mixed concentrate belt sintering". Currently, it has achieved stable and efficient application in the first 4 million tons/year belt pellet production line in Liaoning. This achievement successfully solves the global technical problem of using ultrafine iron concentrate to prepare high-quality fluxing pellet ore, providing a mature technical path for carbon reduction in the iron and steel industry in China.
