Abstract
Occurrence state of rare earth is the key issue for mineralization and development of ion adsorption rare earth ore.Rare earth resources are abundant in western Guangdong,but mineralogy research is weak.Taking a rare earth ore in a weathering crust in western Guangdong as the research object,the occurrence state of rare earth is studied by polarizing microscope identification and ammonium sulfate room temperature leaching test.The results show that no isolated rare earth minerals such as monazite are found in the ore-bearing rock mass,and the ion phase leaching rate of ores in multiple target areas is 64.00%to 92.86%,which is relatively high on the whole.Rock and ore identification and leaching data show that rare earth elements do not form independent crystalline minerals,and are mainly adsorbed on the surface of clay minerals in exchangeable ion state,and the deposit type belongs to weathering crust ion adsorption rare earth ore.关键词
