对大峪口磷矿的浮选产物进行X光衍射研究发现,不同浮选产物中磷灰石晶胞参数a及轴比c/a呈规律性变化,说明磷灰石中CO_3~(2-)对PO_4~(3-)的取代是使其与脉石矿物分离性变差的主要原因。
X-ray diffraction of flotation products of Dayukou phosphate rock shows that the parameters a and axial ratio c / a of apatite vary with different flotation products, indicating that CO_3 ~ (2- The substitution of PO 4 - (3 -) is the main reason for its poor separation from gangue minerals.
