[Ferro-alloys.com]At present, most manufacturers use MnCO3 ore to produce EMM and the smelting craft is quite mature. It is still a worldwide technical problem to produce EMM with manganese sulfide ore (MnS). China Tyoon Group’s Sichuan Brunch has abundant Mn ore reserves. But 70% of them are MnS ore and only 30% are MnCO3 ore. In order to promote the EMM project in Sichuan, China Tyoon Group signed a project contract with Changsha Research Institute of Mining and Metallurgy Co.,LTD in December 2014. They will collaborate to study EMM production craft with MnS ore. This research will extend China Tyoon Group’s superiority on EMM technology and improve its comprehensive strength.
