磁铁矿

In silicate minerals and magnetites existed isomorph tin.

硅酸和磁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.

山东省滨海砂石英、锆英石、磁、砂金等为主,其次为贝壳、球石、钛、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).

主要构成除磁和铝榴石外，矽卡岩尚有其他如符山石，阳起石，绿帘石，萤石及钙榴石。

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%和50%的两种烧结中氧化均、磁为主，粘结相主要酸钙、硅酸二钙和玻璃质为主，但酸钙数量不多。
