磁铁矿

In silicate minerals and magnetites existed isomorph tin.

硅酸盐物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.

山东省滨海砂以英、锆英、磁、砂金为主,其次为贝壳、球、钛、金。

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

主要构成物除磁铝榴外，矽卡岩尚有其他物如符山，阳起，绿帘，萤及钙榴。

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%的两种烧结中氧化物均以赤、磁为主，粘结相主要以酸钙、硅酸二钙玻璃质为主，但酸钙数量不多。
