俄罗斯领先的全球铁矿石和热煤层铁（HBI）生产商Metalloinvest已宣布在其AndreyVarichev Mikhailovsky Gok宣布推出溢价（DR级）的颗粒生产。飞行员批量颗粒被送到Lebedinsky Gok和Oemk，以便为生产热煤层（HBI）和直接还原铁（DRI）进行工业测试。颗粒中的总铁含量约为68％，二氧化硅和硫含量分别为1.4％和0.003％，满足全球市场对高质量的DR级颗粒的要求。
"We aim to raise the company’s product quality. Previously, Mikhailovsky GOK’s pellets were used in blast furnaces, however with improved quality they will also be in demand for the production of metallized raw materials. Our premium products are going to be used in green steel production chains. DRI/HBI production delivers energy savings of up to 50 percent compared to smelting pig iron, while greenhouse gas emissions are 60 percent lower." Rinat Ismagilov, director of the mining production department of management company Metalloinvest, said
