磁铁矿

In silicate minerals and magnetites existed isomorph tin.

硅酸盐物磁铁中都存在类质锡。

Quartz, zircon, magnetite, gold are major constituents of littoral placers in Shandong province, while shell, ballstone, ilmenite, rutile being secondary.

山东省滨海砂以石英、锆英石、磁铁、砂金等为主,其次为贝壳、球石、钛铁、金红石等。

Apart from magnetite and almandine garnet, the skarn also contains these minerals: idocrase, actinolite, epidote, fluorite and andradite (another garnet mineral).

主要构成物除磁铁铁铝榴石外，矽卡岩尚有其他物如符山石，阳起石，绿帘石，萤石及钙铁榴石。

For sinter with 25% and 50% MAC fines the iron oxides mainly consisted of hematite and magnetite, the bonding phase were mainly dicalcium silicate, glassiness, and a few amount of calcium ferrite.

配比为25%50%种烧结中铁氧化物均以赤铁、磁铁为主，粘结相主要以铁酸钙、硅酸二钙玻璃质为主，但铁酸钙数量不多。
