磷块岩

麦哲伦海山区MA、MC、MD、ME、MF海山的结壳基岩类型主要有玄武岩、火山碎屑岩，其次为灰岩和磷块岩。

The substrate is mainly basalt and volcanic clastic rock , and then limestone and phosphorite in seamounts MA , MC , MD , ME , MF from Magellan seamounts .

含稀土磷块岩普遍具Ce的负异常，显示其对源区的继承性，也指示成磷环境处于氧化程度相对较高状态。

REE-bearing phosphorite has Ce anomaly , showing succession of original region and high oxidation environment during phosphorite formation .

水体倒转的另一效应是将深海负13C的碳酸盐带到浅水区域，碳酸盐盖帽和上覆磷块岩的负δ13C值证实了这一点。

Another result of overturn was the transport of δ 13C depleted carbonate to the shallow water area . The negative excursion of δ 13C in cap carbonates and the overlying phosphorites can confirm this opinion .

采用测定近似功指数的简化试验方法，对贵州织金新华磷块岩矿床下矿层含稀土磷矿石的球磨可磨性进行了测定，得到该矿石的功指数约为16.16kWh/t。

The grindability of ball milling of phosphate ore bearing rare earths was determined by using a simplified test method of determing approximate work index . The work index of the ore was about 16.16kWh/t .

脉石矿物主要为白云石、伊利石、高岭石、铁质。经测定当磷块岩磨矿粒度小于0.1mm，其磷酸盐矿物单体解离率可达92.53%，这为确定合理的选矿流程具有实际意义。

Experiments suggest that when phosphorite ore is grinded up to a grain size below 0.1 mm , as much as 92 % of individual phosphate minerals will be separated from the ore. This suggestion has practical significance for reasonable decision of an ore-dressing flow chart .
