Reserved Titlelron ore is the most importantraw material for the steel industry and a strategic mineral resource of the country. Its level of protection is related to the overall security of the country. iron ore magnetization roasting technology refers to the chemical reaction of heating iron ore under certain atmospheric condions,selectively transforming weak magnetic iron minerals such as hematite, limonite, and siderite into strong magnetic magnetitc or maghemite. in response to the industry commonaly and personalized needs of enterprises, we have developed the NEUH series of high-efficiency and clean utilization equipment for hydrogen basedore phase transformation of complex and difficult to select iron ores, leading a major technoloaical revolution in the world's iron ore beneficiation field. The Mn grade and TFe grade of the manganese ore in the Zambian manganese mining area of liaoning Sanhe Mining are 12%.to 19% and 35% to45%,respectively. Due to the inability to utilize conventional technology, they can only be disposed of as waste rock, with a storage capacity exceeding 10 million tons, causing serious resource waste and environmental pollution problems.
Successfully developed a new technology forthe comprehensive utilization of hydrogen based ore phase coversion magnetic levitaton combined separation of Baoshan medium poor oxideore at Baosteel; Under the condition ofeeding Tfe grade of28.74%, excellent technical indicators of iron concentrate TFe grade of 65.26% and iron recoveny rate of 80.68% were obtained,Carry out the feasibility study ofthe 32 million ton/year hydrogen based mineral phase conversion project and it is expected ta start construction in2022 In response to the difficuties inthe development of overseas iron ore resources, a new idea of"domestic processing and utilization of overseas iron ore resources" is innovatively proposed -overseas iron ore resources are mined and transported backt o China, and hydrogen based ore phase conversion processing plants are built around the port to produce iron concentrate and tailings products,achieving. |
Successfully developed a new technology for the utilization of all components in Hainan Shilu lron Mine,including pre separation desufturzation,suspension magnetization roasting. and magnetic separation.We have achieved excellent technical indicators of iron concentrate grade of 65.68% and iron recovery rate of85,56%,which is3 percentage points higher than the existing process iron concentrate grade and 20 percentage points higher than the iron recovery rate.The main project construction has been completed, and it is expected to be completed in June this year.
