1·Quartz, zircon, magnetite, gold are major constituents of littoral placers in Shandong province, while shell, ballstone, ilmenite, rutile being secondary.
山东省滨海砂矿以石英、锆英石、磁铁矿、砂金等为主，其次为贝壳、球石、钛铁矿、金红石等。
2·Its chief commercial ores are ilmenite and rutile.
有商业价值的主要矿石是钛铁矿和金红石。
3·At the same time, because of ilmenite content in the ore is relative higher, that is advantageous to recovery of titanium and high recovery could be obtained.
同时，矿石中钛铁矿含量相对较高，有利于钛的回收，可获得较高回收率。
4·The most common magnetic muds contain iron filings or magnetite. Other paramagnetic minerals such as hematite and ilmenite may contribute, although their magnetic susceptibility is considerably less.
常用的磁性泥浆含有铁磁质或磁性物质，另外还有一些低磁化率矿物也有贡献，如赤铁矿、钛铁矿。
5·This is part of the ilmenite tailings discharge as a result titanium enormous waste of resources.
这部份钛铁矿作为尾矿排放造成金属钛资源的巨大浪费。
