金刚石与石墨的物理分离技术研究

在对金刚石与石墨混合物的相态及其特性分析的基础上。讨论了重液的种类选择，重液密度的设计与计算，加入表面改性剂对重液的稳定性及分离效果的影响。采用重液选矿法来分离金刚石与石墨，并达到了预期的效果。

Study on the Physical Separation Technology of Diamond and Graphite

On the basis of analyzing the phase-states and properties of the mixture of diamond andgraphite,the selection of heavy fluids and their designs and calculations of density are discussed. The influence adding on separation and stability of heavy fluids by adding surfactants are also studied. By heavy fluids mill diamond and graphite can be separated,and the expected purpose also reached.
