包头白云鄂博矿山是铁、稀土、铌资源极其丰富的综合性矿床,为发展我国稀土冶金工业提供了雄厚的物质基础。包钢在“以铁为主综合利用”方针的指引下,在选铁的同时回收部分稀土精矿,目前包钢采用浮选——重选工艺流程已形成年产万吨稀土精矿的能力。但产品质量低,精矿品位(TR_2O_3)在20～30％之间,约合60～70％的杂质矿物,这种低品位精矿
Baotou Bayan Obo mine is an iron ore, rare earth, niobium resources are extremely rich in comprehensive deposits, for the development of China’s rare earth metallurgical industry has provided a solid material foundation. Baotou Steel in the “iron-based comprehensive utilization” under the guidance of guideline, while the iron in the recovery part of the rare earth concentrate, the current Baotou flotation - re-election process has been formed with an annual output of 10,000 tons of rare earth concentrate capacity . However, the product quality is low, and the concentrate grade (TR_2O_3) is between 20 and 30%, accounting for 60% to 70% of the impurity minerals. The low grade concentrate
