Sparse soil grade in the magic mineral series tail mineral ReO usually is %, and every year exhaust about 2021 thousand tons, these are precious resources, to research recovering the sparse soil concentrate mineral from the tailer mineral of the magic mineral series, the purpose is from research in the lab, for the sparse soil characteristic, float choose and apply to produce in the industry. The sample ReO taken to research is %, through one raw two concentrate sparse soil, acquire the sparse soil of concentrate mineral grade is %, the operation recovery rate is %。 the sample ReO taken to research is %. Through one raw two concentrate operation, acquire the sparse the soil concentrate the mineral is %, the operation recovery rate is %. In the meantime synthesize better sparse soil collector XP2 during the period of experiment with correspond of forming agent XF2. In the meantime of the produce process research, to carry on the research of the craft of the weak magic the sparse soil tailer mineral and in the sparse soil concentrate mineral, providing the theories instruction for the later research. 內(nèi)蒙古科技大學(xué)畢業(yè)論文 III Key Words: Baiyunebo deposit, weak magic separation tails, rareearth, flotation 內(nèi)蒙古科技大學(xué)畢業(yè)論文 IV 目 錄 摘 要 ............................................................
