Chengde: The local open-pit iron mines are relatively concentrated. In April, some mines passed the acceptance inspection. Their explosives supply returned to normal and the beneficiation plants resumed production. However, the production resumption was slow; some mines said that they need to expand capacity to meet the new requirement for resumption, and it would take some time; some large mines also said that they need to rebuild their explosive depots and will delay the production process.
