白云鄂博铁铌稀土矿床是个多金属共生矿床,这一概念是经过历年多次地质工作逐步形成的。1927年丁道衡发现了主矿,1944年黄春江发现的东矿和西矿,1950～1954年241队对主东矿进行了详细勘探,对西矿进行了初步勘探,主要是以铁矿资源为主进行的地质勘探工作,从而建成了包头钢铁公司。因1935年何作霖发现有两种稀土矿物,严济慈并测定了其中的镧、铈、镨、钕等稀
The Bayanobo iron-niobium rare earth deposit is a polymetallic symbiotic deposit, and this concept has been gradually formed after many geological work over the years. In 1927, Ding Daoheng discovered the main mine and the East Mine and West Mine found in Huangchun River in 1944. The 241 team from 1950 to 1954 conducted a detailed exploration of the main Dong Mine and carried out preliminary exploration of the Western Mine, mainly based on that the iron ore resources were The main geological exploration work, which completed the Baotou Iron and Steel Company. Due to the discovery of two rare earth minerals by He Zuolin in 1935, Yan Jici measured the contents of lanthanum, cerium, praseodymium and neodymium among them
