为充分了解磷尾矿的矿石性质,为磷尾矿的资源化利用提供技术思路,利用MLA、偏光显微镜、电子扫描显微镜(SEM)、粒度分析仪,研究云南某磷尾矿的矿物组成、主要矿物颗粒和有害杂质的赋存状态、嵌布特征、共生关系和粒度分布等矿物学特征。结果表明,磷尾矿粒度较细,作为土壤调理剂,或提供钙、镁源作为生产含镁或含钙物质的原料时,具有粒度较细,无需研磨的优势,但不利于充填体强度的增加;磷尾矿中含有大量的钙、镁、磷等中量元素,同时重金属含量均低于肥料中有毒有害物质的限量要求(GB384002019);有害杂质As和Pb在磷尾矿中的粒度分布具有两边高、中间低的趋势,可以考虑分级的方式脱除富集As和Pb的粒级;磷尾矿中的磷灰石含量较少,且单体解离度低,难以通过浮选分离;磷尾矿中重金属Pb主要赋存于方铅矿和白铅矿中,分配率分别为74.68%和25.32%,方铅矿和白铅矿单体解离度高,绝大部分为单体颗粒,有利于分离;重金属砷赋存于褐铁矿中,褐铁矿单体解离率极低(33.79%),不利于矿石脱砷。试验通过工艺矿物学研究,分析了磷尾矿的矿物学特征与其资源化利用的关系,并提出有害杂质脱除的最优方法,对磷尾矿的资源化利用具有重要意义。

The P-wave velocity structure in the shallow crust is investigated in and around the Sulu-Dabie region by using seismic reflection data for deep soundings in 48 survey profiles and from rock velocity *** observed velocity distributions show obvious heterogeneities in this *** low velocity anomalies are observed mainly in the west of the Dabie region and the East Sea *** high velocity anomalies emerge in the shallow crust of the Sulu and Dabie *** high-velocity anomalies can be attributed to the ultra-high pressure metamorphosed(UHPM)rock formed by exhumation motion of mantle materials during the *** high-velocity anomalies in the different shallow layers beneath the Sulu region are located to the northeast of the Tan-Lu *** high-velocity anomalies beneath the Dabie region are located southwest of the Tan-Lu *** a distribution pattern of velocity anomaly zones may reveal historical motion of a left-lateral strike-slip for the Tan-Lu fault,which differs from the result of a right-lateral strike-slip motion regime known from modern seismology,indicating a more complex tectonic motion along the Tan-Lu fault.
