磁铁矿

In silicate minerals and magnetites existed isomorph tin.

硅酸盐物和磁铁中都存在类质同象态锡。

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

山海砂以英、锆英、磁铁、砂金等为主,其次为贝壳、球、钛铁、金红等。

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

主要构成物除磁铁和铁铝外，矽卡岩尚有其他物如符山，阳起，绿帘，萤及钙铁。

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.

比为25%和50%的两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、硅酸二钙和玻璃质为主，但铁酸钙数量不多。
