• Resumen

  • The halting of operations at several small companies, magnesia producers being able to pay cash on delivery, magnesia kilns halting operations for environmental protection (341 kilns in Daashiqiao and 529 kilns in Haicheng) and a rise in coal prices propelled the domestic Chinese magnesia price higher. Magnesia imports from North Korea into China in 2016 were 114,876 tonnes of CCM (97% of total imports) at an average price of $170 per tonne, 27,810 tonnes of DBM (89%) at an average price of $162 per tonne and 2,360 tonnes of FM (95%) at an average price of $390 per tonne. After blasting ore is crushed and screened into 3/10/25/50 mm sizes, optical sorting is carried out on the material larger than 25mm material and prime grades high grade (HG), technical grade (TG) and standard grade (SG) are produced. Only 6-7% of the deposit has been drilled by reverse circulation (RC) and diamond core drilling techniques, compliant with JORC requirements; the Winchester resources are shown in Table 10.After the completion of the company’s prefeasibility study in 2015, Korab established the different stages needed to bring the mine into production.
