Mining Activities In May 2016, Sino Iron achieved a significant milestone when lines five and six joined the other four lines in producing premium magnetite concentrate. CITIC Limited chairman Chang Zhenming said focus would turn to ramping up production and maximising efficiencies across all lines. "There's still a lot of work to do [and] it will take time to optimise line performance but we're headed in the right direction," Mr Zhenming said. "This project represents the realisation of the next phase of iron ore production in WA. "We have shown it is possible to produce steel from resources in WA that have been considered low value until now. "This type of production will be the way of the future and underpin WA's long-term competitiveness as a premier iron ore province." From January 2016 to the end of February 2017, more than 13 million wet metric tonnes (wmt) of premium magnetite concentrate had been delivered to CITIC steel plants and other steel mills in China.
